fidelity, full-duplex communications. The BTR-800 system includes the BTR-800 frequency agile base station, working with up to four TR-800 or TR-825 frequency agile beltpacks. The BTR-800 base station provides full-duplex communications with the beltpacks. The BTR system incorporates two audio channel operation, permitting the beltpack operator to choose between two separate audio channels of communications, with the base station tracking the beltpack selection. This allows the user the flexibility to create a party-line and a private line within the same beltpack. The BTR-800 system is perfectly suited for stand-alone operation and also can interface with Audiocom (Telex), RTS TW, Clear-Com, as well as RTS Matrix systems and other 4-

wire communications systems. In addition to the external intercom systems interfaces listed above, the system provides connections for auxiliary balanced audio input and output, as well as wireless talk-around (WTA) and stage announce (SA) features. The RTS BTR series has been designed for reliable, efficient operation. Operating in the 470 to 722 MHz range, the units operate reliably at line-of-sight distances of 1,000 feet. With available antenna systems, from Bosch, the effective operating range can be extended. The high efficiency beltpacks provide up to 12 hours of uninterrupted operation using standard alkaline batteries. Frequency-agile base station and beltpacks. No external computer/device required to select frequencies.

Backlit base-station LCD allows the user to easily monitor the beltpacks status as well as change base station frequencies.

ClearScan function on base station and beltpack to automatically find the best channels on which to operate.

Full-duplex (simultaneous talk and listen) operation.

Compatible with Audiocom, RTS TW, Matrix, Clear-

Com, and other wired intercom types.

Two channels of intercom audio.

WTA (Wire less Talk Around) beltpack control. This feature allows beltpacks to talk to each other, but their audio is lifted from any wired system connected to the base station.

SA (Stage Announce) beltpack control. Allows the user to direct their audio to a jack on the back of the base for P.A. systems or other external audio systems.

Relay contact closure on the base when the SA button is pressed.

TR-825 features two audio channel binaural operation in either stereo or mono mode.

Beltpack units contained in a weather and shock resistant die-cast magnesium case.

Convenient IEC power connector on the base station so the unit can plug directly to outlets. No in-line or wall plug power supply.

Base station comes with rack ears for easy rack mounting. 8 Introduction BTR-800, TR-800, TR-825 FIGURE 1. BTR-800 Block Diagram CHAPTER 2 BTR-800 Base Station Controls and Connections Front Panel 2. 4. 5. 6. 7. 1. Power Switch

One 1/2-

wave antenna for Transmit and one 1/2-wave for Receive. The antennas have TNC male connectors. The frequency range of the antennas should match the receiver and transmitter of the base station. Match the color code on the antenna with the color code on the base station. Attach the transmit 1/2-wave antenna to the antenna input receptacle labeled Transmit on the right side of the rear panel. The antenna should be vertically aligned. Attaching Transmit 1/2-Wave Antenna FIGURE 10. Attach the receive 1/2-wave antenna input receptacle labeled Receive on the left side of the rear panel. The antenna should be vertically aligned. Antenna Placement BTR-800, TR-800, TR-825 ANTENNAS SHOULD BE VERTICAL FIGURE 12. Vertically Polarized Antennas Distance between Antennas The distance between the base stations receive and transmit antennas is not adjustable when the antennas are connected directly on the back of the unit. The antennas can be remoted for better signal path. An RTS coax assembly with remote antennas may be required. See Accessories and Replacement Parts on page 83 for ordering information. NOTE:

If your base station is to be located in a shielded rack mount enclosure or other poor RF location, you must remove the 1/2-wave antennas with coax assemblies. See Accessories and Replacement Parts on page 83 for remote mounting hardware. Proper antenna placement probably has the most effect on your RTS Wireless Intercom Systems overall performance. The following suggestions will result in optimum performance. Proper placement of the beltpack can be critical. The antennas should be in the open. Bending the antennas up and placing the beltpack in a pocket, etc., will reduce system distance. It is suggested that the unit be worn on the belt with both antennas vertical for best operating range and performance. Attaching Receive 1/2-Wave Antenna FIGURE 11. Antenna Polarization The RTS Wireless Intercom System is Vertically Polarized. This means both the transmitting and receiving antennas should operate in the vertical position. FIGURE 13. Proper Dressing of the Antennas BTR-800, TR-800, TR-825 Initial Equipment Setup 23 Keep the distance between the base station and the beltpacks as short as possible. The greater the distance, the weaker the signal. Make sure the signal paths between the base station and beltpacks are unobstructed. You should be able to visibly locate the base station antennas at all times for best performance. FIGURE 15. Keeping Site Clear to Antenna Attempting to operate the wireless intercom system through or around walls, ceilings, metal objects, etc will reduce system range and performance. FIGURE 14. Distance Between base station and beltpack Operating System Near Obstructions FIGURE 16. IMPORTANT:

Do not mount the base station 1/2-wave antennas on, or next to metal, such as beams, walls with metal studs, equipment racks, etc. This also applies to the antennas when assembled directly to the Base Station. This will detune the antennas which can result in noise or loss of RF signal at the Base Station, see Figure 17. 24 Initial Equipment Setup BTR-800, TR-800, TR-825 FIGURE 17. Antenna Placement Improving Reception and Increasing Range Keeping the distance from the base station and beltpack as short, and unobstructed as possible will produce the most reliable performance. The base station is supplied with two antennas. This should provide satisfactory system performance in most applications. System range can be enhanced by remoting the 1/2-wave antennas. The 1/2-wave antennas are ground plane independent. so a ground plane is not required for good performance. BTR-800, TR-800, TR-825 Base Station Set-up Initial Equipment Setup 25 FIGURE 18. Base Station Rear Panel Location Transmit Switches Locate the base station with the front and rear of the unit accessible so that switches may be set and connections made. Place the transmit and receive antennas on the base station. Make sure the color band match the color dot near each antenna. See Antenna Placement on page 22 for more information on choosing a proper operating location. Power Connection Plug the supplied power cord into the unit. The base station has an IEC power receptacle that accepts 100-240 VAC, 50-60 Hz. The specific receptacle type is an IEC 60320/C14. The cord it accepts is an IEC 60320/C13. These cords are common and available through many retail hardware/electronic stores if the cord is lost. On/Off There are two switches located on the lower left side of the rear panel. The upper switch sets the transmit power levels to high or normal. The lower switch turns the transmitters on or off. Transmit Power Set the power level to normal if using the beltpacks at close to medium distances (<200 feet, 161m, line-of-sight) from the base station. Set the power level to high if using the beltpacks at a distance (>200 feet, 161m, line-of-sight) from the base station. Set the transmitter switch to on for normal use. In the off position both base station transmitters are disabled. Setting the switch to off will disable all the beltpacks from hearing anyone else or even their own sidetone. 26 Initial Equipment Setup BTR-800, TR-800, TR-825 Internal Transmit Switches Intercom Switch Internal to the BTR-800 are two transmit switches which enable a user to turn on or off the two transmitters individually. See Figure 19 for the location. The top cover of the base station must be removed for access. The switch closest to the front panel controls transmitter 1 (audio channel A). The switch behind that is transmitter 2 (audio channel B). The default switch position is to the left if you are facing the front of the base station. This is the ON position of the transmitters. The RTS wireless system can be interfaced to RTS, TW, Audiocom (TELEX), Clear-Com, RTS matrix and other intercom (I/C) systems. Set the Intercom switch on the rear of the unit to the appropriate system and connect the system to the base station. The two intercom channels on the rear of the base station have loop-thru male and female XLR connections for two-wire systems and RJ-11 type jacks for four-wire systems. In the normal use of the BTR-800, there is no need to access these switches. They are used to test the transmitters individually at the factory. This switch only affects the two-wire intercom systems. The function of the I/C XLRs change depending on the intercom selected. Please see Intercom Systems Specifications on page 81 for pinout information of the different two-wire intercom systems. Intercom Interface Audiocom (TELEX) and ClearCom intercom systems require one cable for intercom A and one cable for intercom B in order to interface two channels of intercom to the base station. This interfacing is done through the I/C A and B 3-pin XLR connectors on the rear of the unit. RTS TW intercoms only need to connect one 3-pin cable to one of the four intercom XLR connectors since two channels of audio are carried on one cable. The intercom switch parallels the four XLR connectors when in RTS mode. RTS channel 1 is place on intercom A and RTS channel 2 is placed on intercom B as long as the RTS TW input to the base station is wired as in Intercom Systems Specifications on page 81. Four-wire intercom systems require one cable for intercom A and one cable for intercom B in order to interface two channels of four-wire intercom to the base station. This interfacing is done through the I/C A and B RJ-11 type jacks on the rear of the unit. See Figure 20 for the pinout of the RJ-11 jacks. FIGURE 19. Internal Transmit Switches FIGURE 20. RJ-11 Type/Four-wire Pinout BTR-800, TR-800, TR-825 Initial Equipment Setup 27 Example Interface to an RTS TW System FIGURE 21. 28 Initial Equipment Setup Dual Listen Functionality The base stations main audio board has the option of placing additional parts to enable dual listen. Dual listen allows the mixing of the intercom channels. The mixing will occur locally, within the base station, and is only heard on that base stations beltpacks. The user will have the ability to enable/disable the mix of I/C A into I/C B or vise versa. If you have TR-825 beltpacks, there is no need to install this base option. The level BTR-800, TR-800, TR-825 of the mix can be controlled at the TR-825 via the two volume controls. They will also have the ability to control the level of the mix (-

4dB to -24dB down from the main channel). Removing two surface mount resistors and installing two SPDT switches and two potentiometer enables dual listen. The parts to be installed are shown in Table 1. The two resistors on the bard to be removed are in Table 2.

Board part number 750541does not have locations to place components, however, modification documents may be obtained from Bosch Security Systems, Inc. for those who wish to modify older audio boards for dual listen. Audio Board Part Number and Dual Listen Component Locations FIGURE 22. BTR-800, TR-800, TR-825 Auxiliary Input/Output The input and output 3-pin XLR auxiliary connections are for supplying additional balanced audio into and receiving balanced audio from the base station. The output auxiliary connection only interfaces to intercom B. However, there is an internal switch to control the routing of the input auxiliary audio. See Internal Auxiliary Input Routing Switch on page 29. The input and output auxiliary audio is global. This means the input auxiliary audio is placed on the base local headset, beltpack(s), headsets, and any wired intercom system interfaced to the base station. The intercom channel(s) the input auxiliary audio is placed on depends on the position of the input routing switch. The output auxiliary audio is also taken from the intercom B base local headset, beltpack(s), headsets, Initial Equipment Setup 29 and any wired intercom connected to the base station. A modification document is available from Bosch Security System, Inc. for those who wish to modify the base station so that auxiliary input audio is heard only locally; base local headset and beltpack(s) headsets. Internal Auxiliary Input Routing Switch This switch controls the routing of the input auxiliary audio. This switch has two positions. The B position places auxiliary input audio onto intercom B only (default from factory). The A

& B position places auxiliary input audio onto intercom A and B. See Figure 23 for the locations of this internal auxiliary input routing switch. FIGURE 23. Auxiliary Input Routing Switch 30 Initial Equipment Setup BTR-800, TR-800, TR-825 FIGURE 24. Base Station Rear Panel A relay contact closure is also activated when a beltpack user presses the [SA] button. The contacts are normal open (N.O.). Rating: 1 Amp at 24 volts AC/DC maximum. A Phoenix type connector (supplied) plugs into the relay contact port on the rear of the base station. This connector provides a screw-type closure for an easy connection to wires. Stage Announce / Relay Contacts The stage announce output connector is where the audio exits the base when any of the beltpacks press the [SA] button. The output is balanced audio though a male 3-pin XLR. The state announce output level is set at the factory for 2 Vrms typical output at rated deviation into 600 Ohms. This should be adequate for most applications. There is an internal level adjustment for this output too. See Figure 27 for the location of the small level trimmer. The top cover of the base station must be removed for access. FIGURE 25. Relay Output Schematic Internal Stage Announce Level Control FIGURE 27. FIGURE 26. Relay Contact Jack Adapter (Screw Terminal Adapter) BTR-800, TR-800, TR-825 Initial Equipment Setup 31 FIGURE 28. Base Station Rear Panel Base Station Link This RJ-45 type jack allows the connection of wireless talk around (WTA) to two base station of the same frequency bands. This allows WTA on I/C channel A and WTA on I/C channel B to be the carried through to the other base station attached together via this jack. WTA channel A and channel B is contained within a base station unless the transmit power is off. If it is off, the WTA audio is routed through the base station link cable to the other base that has its transmitter on. A cable to accomplish this task is NOT supplied, but can easily be made with common category 5 (CAT-5) or later wiring. In fact, the most common 10BaseT Ethernet patch cables, 568-B wired cables, can be used to connect bases together. The required cable is shown below. The regular two-wire intercom channels are passed from base to base via the wired intercom cables and do not require the base station link cable. Two Stand Alone Base Stations Connected Together FIGURE 29. FIGURE 30. Base Station Link Cable 32 Initial Equipment Setup BTR-800, TR-800, TR-825 6.

TR-800 and TR-825 Rear Panel Antenna Connection Headset Connection Insert the headset plug into the XLR connector. See the headset pinout in the TR-800/TR-825 beltpack controls and connections section if this is not a Telex headset. A dynamic or electret headset microphone is automatically detected by the beltpack and a bias voltage supplied, if needed. The beltpack comes with two detachable, screw-type, 1/4-wave antennas. To attach the two antennas, screw into the receptacles at the bottom of the beltpack. The color dot on the screw end of the antenna must match the color dot on antenna receptacle. The receive antenna screws into the left receptacle if the beltpack is laying flat with the battery compartment face up and the antenna receptacles facing you. The other antenna is the transmit antenna. New antennas can be ordered if desired, see Accessories and Replacement Parts on page 83. Transmit Mode The rear panel located transmit switch has the following two modes:

Push-to-Talk (PT TALK) Recommended position - The transmitter is always on. No audio is sent unless the talk switch, WTA or SA button is pressed. Push-to-Transmit (PT TX) The transmitter and audio path are off except when the talk switch, WTA or SA button is pressed. 34 Initial Equipment Setup BTR-800, TR-800, TR-825 Pre-Walk-Thru Checklist CHAPTER 6 Connected the base station to any auxiliary audio, intercom, external P.A. system, or relay contact detect circuit, if needed. Installed batteries in the beltpack. If you massed any of the above instructions, go back and complete that instruction before going on. Following the instructions fully to this point you have successfully completed the following checklist:

Located the base station properly. Connected power to base station Connected the 1/2-wave antennas to the base station. Checked frequency range of the antennas with the frequency of the base station by correctly matching color codes. Connected 1/4-wave antenna to the beltpack. Checked frequency range of the antennas with the frequency of the beltpack by correctly matching color codes. Base station transmit power switches in the correct positions. Transmit mode switch on beltpack set correctly. Set wired intercom type correctly. Connected headsets to base stations (if needed) and all beltpacks. 36 Pre-Walk-Thru Checklist BTR-800, TR-800, TR-825 CHAPTER 7 System Operation Frequency Plan Overview The BTR/TR-8XX has 36 factory defined frequency groups and 12 user-programmable frequency groups. A Group defines the two-base station transmit frequencies and thus the two receive frequencies on all the beltpacks. A Channel defines a base station receive frequency and thus a beltpack transmit frequency. A base station receive channel that does not have a frequency set for it will have a dash to the right of it on the Group/Channel select screen. Details on setting frequencies may be found in the BTR 800 Menu Structure on page 40 and TR-

8XX Menu Structure on page 49. Factory-Defined Groups The 36 factory-defined groups were carefully chosen to avoid certain intermod products and various other possible sources of interference. The Groups are set and cannot be changed. There is a limited number of channels which can be chosen from within these groups. The first 24 factory-defined groups (01A 12B) are pair groups that can be used for single (up to four beltpacks) and dual (up to eight beltpacks) BTR-800 systems. They are arranged 01A, 01B, 02A, 02B...011B, 12A, 12B. A pair group, like 1A and 1B, have different base station transmit frequencies, however, they both have the same eight base station receive channels from which to choose. Each channel represents a unique frequency. For example, one BTR-800 could be set on Group 02A and channels 01, 02, 03, and 04. The other BTR-800 could set on Group 02B channels 05, 06, 07, and 08. As long as the channels are different, everything should be fine. The next 12 groups (1324) are single groups that primarily are used for single (up to four beltpacks) BTR-800 systems. The number of channels from which to choose from in these groups will vary from group to group. Three band base stations and beltpacks used in the US have a reduced channel map offering due to regulatory changes that reduced the size of the three band. Please see Section 16 for more information. User-Programmable Groups The 12 user-programmable group are initially empty. The transmit and receive frequencies are fully editable within these groups. In fact, factory-defined groups may be copied to user-

programmable groups and then edited, if desired. See the BTR-

800 Menu Structure on page 40 and TR-8XX Menu Structure on page 49 for details on how to copy and edit frequencies. System Quick Start Follow the list below to quickly get a base station and beltpack(s) operating. When completed the user should have a base station and 1 to 4 beltpacks up and running with full operational ability. The base station will be on Group 01A with its four receivers on channels 01, 02, 03, and 04. Each beltpack will be on Group 01A with a unique transmit channel number matching one of the base station receive channels. 1. Plug-in the base station via the supplied power cord and connect the antennas. The color dots on the base should match the color rings on the antennas. 2. Base station rear panel switches: Transmit power set to High and on. 3. Ensure base station rear panel IC switch matches attached wired intercom system. If used stand alone or connected to a 4-wire system then IC switch position is not applicable. 4. 5. Press [MENU] as powering-up the base station. This will place it on group 01A and set the receives on channels: 01, 02, 03, and 04. Place the front panel IC A and IC B IN and OUT level controls in the 12:00 oclock position. Check that front panel IC A and B is in 2-wired for AudioCom (Telex), RTS-

TW and ClearCom wired systems, and 4-wired for RTS Matrix and stand-alone operation. 6. Pace batteries in the beltpacks. 7. Remove the rear switch cover on the beltpacks. Set the beltpack rear panel slide switch to push-to-talk (PT TALK). 8. Press [MENU] as powering-up each beltpack. This will place the beltpack on group 01A with the channel 01 flashing. 9. Use the [UP] and [DOWN] arrow buttons to change the channel to match a channel on the base station. Then press

[SET]. If leaving on channel, just press [MENU]. Each beltpack should have a unique channel number. 10. The group/channel on the beltpack should now match the group and receive channel on the base station. Nothing should be flashing on the beltpack screens. 11. Plug headsets into the beltpacks and set the microphone gain so the BAT/OM LED will flash at the beginning of most words at normal speech levels. 12. DONE. 38 System Operation Base Station Operation BTR-800, TR-800, TR-825 FIGURE 34. Base Station Rear Panel Power If you have followed the instructions in Section 4, Initial Equipment Setup, you should now be ready to turn the base station on. Set the base station power switch to the on position, by pushing the top of the switch. The internal cooling fan will start immediately and the LCD display and front panel indicator lights will come on in five or six seconds. Local Headset Talk Button Press to enable the audio path from the local headset. The TALK/O.M. LED will turn green when audio is enabled. A quick press and release latches on the button. If the talk function is latched on, pressing the talk button again will turn it off. If the local headset is not being used, the talk button should be off. This keeps additional noise out of the system. Microphone Gain Adjusts the headsets microphone gain. Adjust so the TALK/O.M. LED flashes from green to red on loudest speech. Headset Intercom Select Button Select the intercom system to connect to the local headset. Each press of the [SELECT]

button changes the connection; Channel A, Channel B, and Both. The cycle will then repeat. The LEDs above the

[SELECT] button light to indicate the current selection. Volume Adjust the volume to the headset by rotating the volume control as required for a comfortable listening volume. Portable Station Connect Select the audio paths from the base stations four receivers that you wish to enable. The corresponding LED above the select button is on when the audio path is enabled. If a beltpack user has their portable station connect path off at the base, that user will no longer hear their sidetone and their audio will not be passed to anyone. The user will still be able to hear everyone. The selection is retained in non-volatile memory, so it will come up where last left if the unit is power cycled. Always disable unused audio receive paths. This reduces the chances that external RF noise can get onto the audio buses via an open receiver. Intercom A and B Intercom Select Button Press the [SELECT] button to choose between 2-wire or 4-wire intercom systems. The green LED will indicate the current mode of the intercom channel. If the base station is connected to a 2-wire system, such as Audiocom (Telex), RTS TW or Clear-Com, set the intercom to 2-wire. If it is connected to a 4-wire system, such as RTS Matrix, set the intercom to 4-wire. It is also possible to have intercom A connected to a 2-wire system and intercom B connected to a 4-wire system or vice versa. The selection is retained in non-volatile memory, so it will come up where last left if the unit is power cycled. In Level Control Adjusts the audio level of the wired intercom systems input to the base station. Out Level Control Adjusts the audio level of the base stations output to the wired intercom system. If the base station is used stand-alone, no wired intercom system connected, it must be set in the 4-wire mode. The 2-wire mode requires a wired intercom system or appropriate load be connected to the intercom A or B XLRs. If not loaded, a large gain increase will take place in the unload intercom channel which may be high enough to produce a loud howling sound. Auxiliary Auxiliary Input Select Button Press the [SELECT] button to turn on or off the auxiliary input to the base station. The selection is retained in non-volatile memory, so it will come up where last left if the unit is power cycled. In Level Control Adjusts the audio level of the wired auxiliary systems input to the base station. Out Level Control Adjusts the audio level of the base stations output to the auxiliary XLR plug. The auxiliary output connects only to intercom B. It does not interface to intercom A. The auxiliary input may be switched to B intercom (default) or A and B intercom. SeeInitial Equipment Setup on page 21 for the location of this internally located input routing switch. The auxiliary output is always available at the back panel output XLR. It cannot be switched on or off like the input. Both the input and output are balanced audio ports. Auxiliary input and output audio is global. See Initial Equipment Setup on page 21for more details. BTR-800, TR-800, TR-825 System Operation 39 Display Contrast The LCDs (Liquid Crystal Display) contrast is set from the factory to a standard level. However it is possible for the user to adjust the contrast, if desired. The contrast control is internal to the BTR-800 unit near the front panel.

After about 20-30 seconds, the group with the highest number of clear receive channels will be displayed. The next best group and so forth may be accessed with the [DOWN] and [UP] arrow buttons.

Press and hold [MENU] + [SET] for three seconds to enter ClearScan. The base station will now start searching all groups for the ones with the greatest number of receiver channels clear of interference.

ClearScan will display the group that has the most interference free receive channels. These clear channels are displayed on the right half of the screen. Press [SET] to place the base station on this group and return to the operating screen. The first four receive channels displayed will be the ones set for the group. The [UP]/[DOWN]

buttons may be used to select the next best group and so forth. To achieve the best results quickly when using ClearScan, please complete the following for setting up a sing BTR-800 system:

Turn off all wireless intercom and wireless microphone equipment.

Turn on all wireless microphones and wireless monitor transmitters. Make sure that this equipment is distributed at least 3 to 5 feet apart from each other to minimize any frequency intermodulation effects.

Turn on one TR-700/800/825 and perform the ClearScan function as described on page 55 and page 66 of this manual.

When the first result is displayed on the TR, write this down along with the next 6 or 7 results. This number represents the specific BTR transmitter that should provide the best results for operation. This is referred to as the Group.

Once you have recorded the first 6 or 7 results from the TR, turn off the TR unit.

Turn on the BTR-700 or BTR-800 and perform the ClearScan function as described above. The results of the BTR will provide the number of Channels or TR transmitters that can operate in a given group.

Since you have already established the best BTR Group

(base station transmit frequency) to operate on, selection of the operating channels is now much easier.

Simply match the number of TRs to operate on your system with the first and best Group number that you have recorded.

When you have scrolled to the appropriate Group number that displays the number of beltpacks to be used on the system, simply press [SET] on the BTR to place the BTR on the selected Group and Channel.

Finally, go back to the TRs and program to the appropriate Group and Channel. BTR-800, TR-800, TR-825 System Operation 47 Special Key Sequences Lockout

Adjust the volume to the headset by rotating the volume control as required for a comfortable listening volume. Battery Check When the beltpack power is turned on by rotating the knob, the BAT/OM LED will flash once if the battery is good. If the LED stays on, the battery is low. If the LED does not flash, the battery is dead. Talk Button Press the talk button to enable the audio path from the headset microphone. The TALK/OM LED will turn red when audio is enabled. A quick press and release latches the talk function unless latching has been disabled. Holding the button for over 1/

2 a second will cause the audio path to be enabled only for as long as the button is held. If the talk function is latched on, pressing the talk button again will turn it off. See Talk Button Latch on/Latch off on page 57 to learn how to enable/disable latching of the talk button. Microphone Gain Adjusts the headsets microphone gain. Adjust so the TALK/

OM LED flashes red at the beginning of most words at normal speech levels. If the input is too large, the LED will be red during the complete word at normal speech level. The peak-

responding audio limiter in the beltpack is very tolerant of high input audio levels. Even when the microphone gain is maximized, and headset volume reduced to make up for the louder audio, the audio will still sound good and not clipped. Audio Channel Select Button Selects the intercom system to which the headset is connected. The LED near the channel button indicates the current selection. See the Audio Channel A or B Disable/Enable on page 57 to learn how to enable only channel A, channel B, or both. Stage Announce (SA) When pressed the audio from the beltpack is routed directly to the stage announce connector on the back of the base station. The base stations SA relay is also closed. The beltpack sidetone is lost as an indication that stage announce is activated. The other beltpacks and wired users do not hear this beltpacks audio when SA is pressed. The button is non-latching and activates the nearby red LED when pressed. See Stage Announce Enable/

Disable on page 56 to learn how to enable/disable the SA button. Wireless Talk Around (WTA) When pressed, the audio from the beltpack is disconnected from the wired intercom, auxiliary input/output and the base stations local headset. Other beltpack users, on that audio channel, can hear the user as normal. The button activates the nearby red LED as well as the appropriate talk LED when pressed. See the Wireless Talk Around Enable/Disable on page 56 to learn how to enable/disable the WTA button as well as other features.

Poor antenna location

Wrong antenna for receiver and/or transmitter

RF trouble spots

Operating distance beyond system capability

Old or used batteries in the TR-8XX Under normal conditions, the base stations display will indicate a beltpack status. Weak Signal condition will result in no tx being displayed on the base stations receiver for that beltpack. In 99% of all instances you will set up you RTS Wireless Intercom System, walk it through the area of interest and achieve error-free performance. If in the rare instance, your RTS system does not pass during your walk-thru evaluation, refer to the section of this manual which deals with System Troubleshooting. Now that you have successfully set up your RTS Wireless Intercom System and turned on any auxiliary equipment, you are ready to test the overall performance by walking the RTS system through the areas in which you will be using it. Before you begin your walk-thru, check the following:

Beltpack Battery Check. Set microphone gain in both the beltpack(s) and the base station. The base station and beltpack(s) are on the same group and the beltpack(s) are on their own unique transport channels that match the base station receive channels. Check that the talk button is engaged. The talk LED will be illuminated. Intercom Level IN and OUT are set to an appropriate level. Auxiliary Level IN and OUT are set to an appropriate level (if used). 74 System Walk-Thru BTR-800, TR-800, TR-825 CHAPTER 9 Troubleshooting Reread the sections of this manual to make sure you have completed system set up properly If you are unable to solve the problem, contact the dealer from whom you purchased the system for assistance. PROBLEM SOLUTION DISTORTION - Systems audio quality seems distorted at medium to high input levels. Reduce microphone gain by adjusting microphone gain control. HISS - System seems to produce a hiss which is undesirable. LOW OUTPUT - System produces a low output level. Check the gain setting on all beltpacks and the base. They may be too low or too high. Check to make sure you are still well within range of the base station. Check the gain setting on both the beltpacks and the base. They may be too low. FEEDBACK - Moving around area of use produces squeal or howl in various locations using ext. speakers. Reduce the gain settings on both the beltpacks and the base. They may be too high. DROPOUTS - When moving around the area of use there seems to be locations where the signal swooshes or completely disappears INTERFERENCE - System picks up signals other than wireless intercoms. NO AUDIO from BASE or BELTPACK headsets. BASE and BELTPACKS Frequencies Dont Match - In the display frequencies screen of the base and the menu of the beltpack the frequencies dont match. Make sure both antennas on the base and beltpack are connected and follow the location suggestions. Change the location of the base unit and antennas or avoid the bad areas with the remote beltpacks. Make sure that all the RTS beltpack(s) are on. If there are any unused receivers at the base, turn the audio off from those receivers by deselecting the appropriate Portable Station Connect button. If problems persist with the beltpack on, you will probably need to change the group. Make sure the base and beltpack match after any Group/Channel change. Check Transmitter switch on base and beltpack. Check talk LED to make sure it is on. Make sure beltpack batteries are OK. Ensure the units are on the correct Group and Channels. If three band base and beltpack units and in the US make sure you have switched the base station to the US channel map, see Troubleshooting on page 75. 76 Troubleshooting BTR-800, TR-800, TR-825 CHAPTER 10 Tech Tips system is distortion on louder speech. The microphone gain must be reduced. The same applies to a user with a powerful voice. If someone sets the system mic gain to their voice and user has a much stronger voice, then the gain will need to be reduced, even if the background noise is the same. Always remember to set the microphone gain based on the situation and location in which the equipment will be used. If the equipment is used on the field during a football game, set the gain based upon a loud stadium, NOT a quiet stadium 2 hours before a game. If a production studio users has a quiet voice, set the gain to their voice and NOT the stage hands loud voice who helped set up the system. Frequency Interaction Unfortunately, radio frequency (RF) channels cannot be randomly selected for use in radio devices. They must be selected to avoid know frequencies in use, FCC restrictions on the location of devices, and even interference between your own RF devices. The factory defined frequencies (Groups 01A-24) selected by RTS for this wireless system are chosen to minimize possible interference. Microphone Gain Adjustment The microphone gain controls on the base station and beltpack are set to mid-levels by the factory. In most cases this setting will work fine and only on loud speech will the over-modulation

(OM) indicator light. However, in environments where the background noise is loud or the user has a strong/quiet voice, the gain control will need to be adjusted. In Figure 40 the gain is set correctly. The users root-mean-square (RMS) sound level is well below the OM threshold and only on peaks does his or her voice flash the OM indicator light. FIGURE 41. High Noise Environment Microphone Gain Set Too High FIGURE 40. Low Noise Environment Microphone Gain Set Correctly Figure 41 displays the same gain setting as in Figure 40 but brought into a high noise environment. The users voice now lights the OM indicator all the time he or she speaks due to the higher noise plus the user speaking louder. The result on the 78 Tech Tips BTR-800, TR-800, TR-825 CHAPTER 11 Battery Information Improper battery selection, use, installation and care are the cause of numerous wireless system failures. Battery Life:

Alkaline Batteries: Alkaline batteries such as Evereadys ENERGIZER1 and ENERGIZER INDUSTRIAL provide the most reliable operation in wireless transceivers. The use of low cost carbon-zinc batteries is NOT recommended. TR-800 Alkaline, 11-13 hours, typical Nickel Metal Hydride, 10-12 hours, typical TR-825 Alkaline, 8-10 hours, typical Nickel Metal Hydride, 7-9hours, typical Nickel-Metal Hydride Batteries - These batteries can save you money in the long run, as they can be recharged. Typical battery life is a little less than the length of time alkaline batteries last. Battery Warnings Cold Temperatures and Batteries The battery life times listed in this section are at room temperature. Alkaline and Nickel-Metal Hydride battery service hours fall off significantly at low temperature due to battery chemistry. Alkaline batteries typically have less than half their room temperature service life if used at freezing 32 F (0 C). If you use Alkaline and Nickel-Metal Hybrid batteries at low temperatures, you need to change them more often. Another solution is using Lithium AA cells if beltpacks are to be used in very cold temperatures. Lithium batteries, like the Energizer Ultimate Lithium AA cells, are excellent batteries for cold temperatures. At 15 F (-9 C), Lithium AA cells will last about seven times longer than Alkaline batteries. This equates to two hours for Alkaline vs. 14 hours for Lithium. However, the trade off is Lithium batteries cost more and are less environmentally-friendly than Alkaline batteries. 1. Energizer is a registered trade mark of Union Carbide Corpora-

tion.

Do not place alkaline battery packs in any battery charger. Severe charger and battery pack damage may occur.

Batteries that have been dropped, or otherwise damaged, should not be used and should be discarded properly.

Dropping batteries can crack the internal casing causing leakage or rupture resulting in personal injury or property damage!

Insert batteries properly, with the plus (+) and minus (-) terminals aligned correctly!

Do not mix old and new batteries, batteries of different types, or batteries of different brands. This can cause leakage or rupture, resulting in personal injury or property damage!

Immediately remove exhausted batteries from the battery pack and dispose of properly.

Replace all used batteries in your device at the same time.

Do not put batteries or battery-powered devices in very warm places. Extreme temperatures reduce battery performance and may also lead to leakage.

Use only high quality AA-sized batteries in the battery packs.

When not in use, disconnect battery pack, remove and store batteries in a cool, dry place at normal room temperature until ready to use.

Keep battery contact surfaces clean by gently rubbing with a clean pencil eraser or cloth. 80 Battery Information BTR-800, TR-800, TR-825 Intercom Systems Specifications CHAPTER 12 RTS Input Impedance:

Three Band Base Stations CHAPTER 15 Identifying a Three Band Unit Changing Channel Maps Three band base stations normally have a 18 MHz wide receive range of 650-668 MHz. These three band base stations are designated by having a 3 in the second digit of the two digit band code that is on a label on the rear panel of the unit. A three band base station may be changed from a normal channel map to a US channel map and back again with the press of a couple buttons. The current channel map setting is remembered by the unit even if power is removed. 1. At the base stations main operating screen, press and hold the [SET]+[UP] buttons until the switching band text is displayed. The three band map the unit is switch to is displayed. 2. Release the buttons when the switching three band text is displayed. The unit reboots and displays one of the following channel map versions. x30001 = Normal three band channel map x3U001= US three band channel map

(where x is the current transmit band of the base station. Regulatory Changes and the Three Band There are two channel map configurations in a three band base station. One for the US/Canada and one for the rest of the world. At one time (before October, 2018) there was only one channel map for a three band unit, but due to regulatory changes in the US/Canada an additional map was produced and installed in three band base stations. The result of the FCC incentive auction in regard to wireless intercom was the following:

Only 10 MHz (653-663 MHz) may be used for wireless intercom in the range 616 MHz to 698 MHz.

Three band beltpack transmit power must be reduced to 20 mW EiRP for US/Canadian units. Since the three band units are made for worldwide customers the 18 MHz range is the default shipped, therefore a US/

Canadian user must set a base station to the new US channel map in order for the bases channel map to match the US three band beltpacks channel map. The US three band beltpacks only have the new US channel map in them. NOTE:

Only US/Canadian users of a three band base station need to change the channel map of the base station to the US channel map!
