ety of electret microphones used in professional appli-

cations has caused confusion and compromises in the wiring needed for wireless transmitters. To address this problem, the unique Servo Bias input circuit provides an automatically regulated voltage over a very wide range of current for compatibility with all microphones. Digital Hybrid Wireless Technology All wireless links suffer from channel noise to some de-

gree, and all wireless microphone systems seek to mini-

mize the impact of that noise on the desired signal. Con-

ventional analog systems use compandors for enhanced dynamic range, at the cost of subtle artifacts (typically pumping and breathing). Wholly digital systems defeat the noise by sending the audio information in digital form, at the cost of some combination of power, bandwidth and resistance to interference. Digital Hybrid systems overcome channel noise in a dramatically new way, digitally encoding the audio in the transmitter and decoding it in the receiver, yet still send-

ing the encoded information via an analog FM wireless link. This proprietary algorithm is not a digital imple-

mentation of an analog compandor but a technique that can be accomplished only in the digital domain, even though the inputs and outputs are analog. Because it uses an analog FM link, the Digital Hybrid system enjoys all the benefits of conventional FM wire-

less systems and it does away with the analog compan-

dor and its artifacts. No Pre-Emphasis/De-Emphasis The Digital Hybrid design results in a signal-to-noise ratio high enough to preclude the need for conventional pre-

emphasis (HF boost) in the transmitter and de-emphasis

(HF roll off) in the receiver. This eliminates the potential for distortion of signals with abundant high-frequency information. Low Frequency Roll-Off The low frequency roll-off can be set for a 3 dB down point at 35, 50, 70, 100, 120 and 150 Hz to control sub-

sonic and very low frequency audio content in the au-

dio. The actual roll-off frequency will vary slightly depend-

ing upon the low frequency response of the microphone. Excessive low frequency content can drive the transmit-

ter into limiting, or in the case of high level sound sys-

tems, can even cause damage to loudspeaker systems. The roll-off is normally adjusted by ear while listening as the system is operating. Input Limiter A DSP-controlled analog audio limiter is employed be-

fore the A-D converter. The limiter has a range of more than 30 dB for excellent overload protection. A dual re-

lease envelope makes the limiter acoustically transpar-

ent while maintaining low distortion. It can be thought of as two limiters in series, a fast attack and release limiter followed by a slow attack and release limiter. The limiter recovers quickly from brief transients, with no audible side effects, and also recovers slowly from sustained high levels to keep audio distortion low while preserving short term dynamics.

+5V 5V Regulator

+6V Variable 1.8 - 4v X1 11.289 MHz 4 X2 12.000 MHz Signal Encoding and Pilot Tone In addition to controlling the limiter, the DSP also en-

codes the digitized audio from the A/D converter and adds an ultrasonic pilot tone to control the squelch in the receiver. A pilot tone squelch system provides a reli-

able method of keeping a receiver output muted (audio mute) even in the presence of significant interference. When the system is operating in the Nu Hybrid mode

(available in US transmitters), a different pilot tone frequency is generated for each carrier frequency to prevent inadvertent squelch problems in multi-channel sytems. Microprocessor Control A microprocessor monitors user command inputs from the control panel buttons and numerous other internal signals. It works intimately with the DSP to ensure the audio is encoded according to the selected Compatibil-

ity Mode and that the correct pilot tone is added to the encoded signal. Control Panel The control panel includes four membrane switches and an LCD screen to adjust the operational settings. Multi-

color LEDs are used to indicate audio signal levels for accurate gain adjustment and for battery status. Variable Power Output This advanced feature allows the operator to optimize the transmitter for maximum battery life, or for maximum operating range. Power output is selected using the LCD in a setup mode while the RF output of the trans-

mitter is turned off. Battery Options and Operating Time Switching power supplies convert regulated battery volt-

ages to operate various circuit stages with maximum efficiency. The firmware remembers the power status when a battery fails, so the transmitter will be turned on auto-

matically when the battery is replaced and the previous settings will be enabled. Circulator/Isolator The RF output circuit includes a one way circulator/iso-

lator using a magnetically polarized ferrite. This device greatly reduces RF intermodulation produced when multiple transmitters are used in close proximity to one another (several feet apart). The isolator also provides additional RF output stage protection against static shock. 5 Controls and Functions Modulation LEDs LCD Battery Compartment Cover Plate UP Arrow Antenna Jack Audio Input Jack DOWN Arrow Battery Compartment Thumb Screw LCD Screen PWR LED AUDIO Button FREQ Button The LCD is a numeric-type Liquid Crystal Display with screens for adjusting power, frequency, audio level and low frequency audio roll-off. The transmitter can be powered up with or without the RF output turned on. A countdown appears in the LCD when powering on and off, allowing the transmitter to be turned on without RF for adjustments, and to prevent accidentally turning it off with momentary button presses. Power LED The PWR LED glows green when the battery is good. The color changes to red when there is about 30 min-

utes of operation left with the recommended lithium bat-

tery. When the LED begins to blink red, there are only a few minutes of life. The exact point at which the LED turns red will vary with battery brand and condition, temperature and cur-

rent drain. The LED is intended to simply catch your attention, not to be an exact indicator of remaining time. Varies Green Red Blink e g a t l o V 1.6 1.4 1.2 1.0

.8 6 Hours 2 4 6 8 A weak battery will sometimes cause the PWR LED to glow green immediately after the transmitter is turned on, but will soon discharge to the point where the LED will turn red or the unit will turn off completely. Power LED Off Feature In normal operating mode, the DOWN and UP Arrow buttons may be used to turn the PWR LED indica-

tors off and on. This setting does not persist through a power cycle nor does it affect the LCD backlight. Antenna Audio Input Jack The Servo Bias input circuitry accommodates virtually every lavaliere, handheld or shotgun microphone avail-

able, plus line level signals. Battery Compartment and Thumb Screw The large knurled thumbscrew is used to release or secure the Battery Compartment Cover Plate. Modulation LEDs Proper input gain adjustment is critical to ensure the best audio quality. Two bicolor LEDs will glow either red or green to accurately indicate modulation levels. The input circuitry includes a wide range DSP controlled limiter to prevent distortion at high input levels. It is important to set the gain (audio level) high enough to achieve full modulation during louder peaks in the audio. The limiter can handle over 30 dB of level above full modulation, so with an optimum setting, the LEDs will flash red during use. If the LEDs never flash red, the gain is too low. In the table below, +0 dB indicates full modulation. Signal Level

-10 LED Less than -20 dB

-20 dB to -10 dB

-10 dB to +0 dB

+0 dB to +10 dB Greater than +10 db AUDIO Button Off Green Green Red Red Off Off Green Green Red The AUDIO button is used to display the audio level and low frequency roll-off settings. The UP and DOWN ar-

rows adjust the values. The AUDIO button is also used with the FREQ button to enter standby mode and to power the transmitter on or off. FREQ Button The FREQ Button displays the selected operating frequency and toggles the LCD between displaying the actual operating frequency in MHz and a two-digit hexadecimal number that corresponds to the equivalent Lectrosonics Frequency Switch Setting. Up/Down Arrows The Up and Down arrow buttons are used to select the values on the various setup screens and to lock out the control panel. The transmitter uses a whip antenna with a flexible wo-

ven, galvanized steel mesh cable and a standard SMA connector. Battery and Battery Eliminator Installation Note: Standard zinc-carbon batteries marked heavy-duty or long-lasting are not adequate. The battery status circuitry is designed for the voltage drop over the life of lithium batteries. To install new batteries:

1. Turn the Battery Cover Plate Thumbscrew counter-

clockwise a few turns until the door will rotate. 2. Insert the new batteries into the housing. The posi-

tive (+) battery terminal goes into the transmit-

ter first. Attaching and Removing the Microphone The flexible sleeve over the 5-pin plug on the micro-

phone helps prevent dust and moisture from getting into the input jack. The flange around the rim of the connec-

tor on the transmitter helps retain the sleeve after it is installed and The following procedure simplifies the attachment and removal of the microphone to assure the sleeve is seated securely. Align the pins on the plug and jack and insert the con-

nector. 3. Align the Battery Cover Plate and tighten the Bat-

tery Cover Plate Thumbscrew. 1 Gore-Tex covered vent Do Not Cover Vent If the sleeve is pulled down and covering the connector, squeeze the end of the sleeve so you can feel the connector inside and press it into the jack until it latches. Pinch and squeeze the sleeve near the flange and work it down with a kneading motion over the flange all the way around until it stays in place flush with the housing. Pull on the connector to make sure it is firmly latched. To remove the connec-

tor, pull the sleeve back to expose the black release button. Press the button to unlatch the plug. Two battery compartments

This setting is accessed by holding Down arrow button while powering the transmitter on. Use the arrow keys to toggle be- tween rc on (remote con-

trol on) and rc oFF (remote control off). The default setting is rc on. Remote Control Screens If a remote control signal is detected but the transmitter is set to rc oFF, the message rc oFF will be dis-

played briefly on the transmitters LCD, to confirm that a valid signal was received, but that the transmitter is not configured to respond to it. Remote functions available are:

The Audio screen is used to adjust input gain from 0 to

+44 dB, and the low frequen-

cy roll-off from 35 to 150 Hz. Repeatedly pressing the AUDIO button toggles back and forth between the two Tx Input Gain Sleep/Unsleep Lock/Unlock Frequency displays. Press and hold the AUDIO button and use the Up and Down arrows to make adjustments.

Repeat-

Changing the low frequency roll-off setting Turning on/off the PWR and Audio LEDs Gain up/down functions In sleep mode, the transmitter uses only 20% of the normal amount of battery drain. Sleep mode can only be invoked with the remote control, and can only be revoked with the remote control or by removing the battery. When in the sleep mode, the PWR LED blinks green every few seconds to indicate that the transmitter is asleep and not turned off. edly pressing the FREQ button toggles between the two displays. Press and hold the FREQ button and use the Up and Down arrows to select the frequency. Lock/Unlock Screen Simultaneously pressing and holding both the Up and Down arrow buttons during normal operation starts the Lock timer. The timer starts at three and counts down to zero. When the timer reaches zero, the transmitters controls are locked. With the controls locked, the AUDIO and FREQ buttons can still be used to display current settings. Any attempt to change a setting by pressing either the Up or Down arrow button will result in an on-screen Loc reminder that the controls are locked. Remove the batteries to unlock the control panel. Important: Once the transmitter is locked, it cannot be unlocked or powered off using the buttons. The only ways to unlock a locked transmitter are to remove the battery or unlock it via the RM remote control. 9 NOTE: See LectroRM for more information. Configuring for Power Restore Set Up in 100 kHz Mode When using external power source through a battery eliminator, Power Restore will return your transmitter to settings it had before it was powered off. This eliminates the need to power on through the unit itself. Power Restore Screens 1) Press and hold the Down Arrow Button then power on the transmitter by pressing the Audio and Freq buttons simultaneously. 2) The LCD will display the status, either rc ON or rc OFF. Press AUDIO or FREQ key to scroll to the PbAc setup screen PbAc 1 for power restore ON PbAc 0 for power restore OFF 3) When power restore is set to ON, the unit will turn on whenever power is present at the battery termi-

nals until the power is manually turned off with the control panel switches. NOTE: The firmware remembers the power status when a battery fails, so the transmitter will be turned on automatically when the battery is replaced and the previous settings will be enabled. Power Up and Boot Sequence Setting Transmitter Operating Frequency Frequency displayed in MHz Frequency displayed as two-digit hexadecimal number The frequency can be displayed either in MHz or as a two-digit hexadeci-

mal number and can be set in the Standby Mode or when the transmitter is powered up. The hexa-

decimal numbering system is unique to Lectrosonics where two alphanumeric characters correspond to the left and right switch settings on earlier analog transmitters that had mechanical rotary switches to adjust frequency. 1) Press the FREQ button to select either the MHZ screen or the hexadecimal screen. 2) While holding the FREQ button, use the Up or Down arrow buttons to move the operating fre-

quency up or down in 100 kHz increments from the current setting. Note: The operating frequency displayed on the LCD wraps as it reaches the upper or lower end of its range. Most Lectrosonics receivers with an LCD interface indicate the operating frequency both in MHz and as a two digit hexadecimal number. In many cases, it is more convenient to use the two character hexadecimal num-

bers rather than the six character frequency in MHz. 10 The Frequency Screen displays the operating frequency in MHz or as a two-digit hexadecimal number that corresponds to the equivalent Lectroson-

ics Frequency Switch Setting. The example of the two-digit display shown here indicates CH (channel) and 2C as the frequency. Repeatedly pressing the FREQ button toggles between the two displays. Press and hold the FREQ button and use the Up and Down arrows to select the frequency. Set Up in 25 kHz Mode The hexidecimal display in the 25 kHz mode will appear with a decimal suffix to indicate the 25 kHz steps. 471.800 MHz 472.025 MHz 472.650 MHz 473.175 MHz Adjusting the Low Frequency Roll-off Repeatedly press the AUDIO button until the LF roll-

off adjustment screen appears. Then press and hold the AUDIO button while selecting the desired roll-off frequency with the UP and DOWN arrows. The roll-off frequency can be set to 35, 50, 70, 100, 120 and 150 Hz. Adjusting Audio Level (Gain) The control panel Modulation LEDs indicate the audio level and limiter activity. Once set, the transmitters audio level setting should not be used to control the volume of your sound system or recorder levels. This gain adjustment matches the transmitter gain with the microphones output level, the users voice level and the position of the microphone. The audio input level (gain) is adjusted with the unit in the Standby Mode or while powered up while observing the LEDs. It is desirable to to set the gain so that some limiting occurs on louder peaks. The limiter is very transparent and its effect is not audible until the system is close to overload. In other words, dont be shy about turning up the gain. It is actually a good idea to turn the gain up to maxi-

mum and listen for distortion or compression to get a feel for how much headroom is available. Signal Level

-10 LED Less than -20 dB

-20 dB to -10 dB

-10 dB to +0 dB

+0 dB to +10 dB Greater than +10 db Off Green Green Red Red Off Off Green Green Red Note: Different voices will usually require different gain set-

tings, so check this adjustment as each new person uses the system. If several different people will be using the transmitter and there is not time to make the adjustment for each indi-

vidual, adjust it for the loudest voice. 1) With the transmitter powered off, plug in the mi-

crophone and make sure the connector is firmly seated. Warning: If the systems is powered up while connected to a live sound system, be careful to turn the sound system level down first or severe feedback can occur. 2) Place the transmitter in Standby Mode or turn it on for normal use. 3) Position the microphone in the location where it will be used in actual operation. 4) Observe the Modulation LEDs while speaking or singing into the microphone at the same voice level that will be used during operation. While holding the AUDIO button, press the UP or DOWN arrow buttons until the both the -20 and -10 LEDs glow green, with the -20 LED occasionally flickering red. This will maximize the signal to noise ratio of the system with full modulation and provide subtle limit-

ing to prevent overload and audible compression. 5) If the unit was set up in Standby Mode, it will be necessary to turn the transmitter off, then power it up again in normal operation so the RF output will be on. Then the other components in the sound or recording system can be adjusted. The Lock mode protects the transmitter from acciden-

tal changes to its settings. Simultaneously press both the Up and Down arrow Control Panel Locked buttons to start the countdown timer. When the timer reaches zero, Loc is displayed and the controls are locked. Settings can be reviewed but not changed. Once the transmitter is locked, it cannot be unlocked or powered off using the buttons. The only ways to unlock a locked transmitter are to remove the battery or unlock it using the remote control. The remote control will work only if the transmitter was previously configured to respond to the remote control. The unit will always power up in unlocked mode. 5-Pin Input Jack Wiring The wiring diagrams included in this section represent the basic wiring necessary for the most common types of microphones and other audio inputs. Some micro-

phones may require extra jumpers or a slight variation on the diagrams shown. It is virtually impossible to keep completely up to date on changes that other manufacturers make to their products, thus you may encounter a microphone that differs from these instructions.

Line Level Signals The normal hookup for line level signals is: Signal Hot to pin 5, Signal Gnd to pin 1 and pin 4 jumped to pin 1. This allows signal levels up to 3V RMS to be applied without limiting. If more headroom is needed, insert a 20 k resistor in series with pin 5. Put this resistor inside the TA5F con-

nector to minimize noise pickup. 1) If necessary, remove old connector from microphone cable. 2) Slide Rubber Boot onto microphone cable with the large end facing away from the microphone. (See illus-

tration above.) 3) If necessary, slide the 1/8-inch black shrink tubing onto the mircrophone cable. (This tubing is needed for some cables to ensure the cable fits snugly in the rubber boot.) 4) Use the resistors and connector included with this kit to configure the TA5F to your particular microphone.

(See Wiring Diagrams below.) A length of .065 OD clear tubing is included if insulating the resistor leads or shield wire is necessary. (Remove rubber strain relief from connector backshell by pulling it out of the backshell.) 5) Slide the Strain Relief over the TA5F Insert and crimp as shown to the right. Then insert the TA5F Insert and Strain Relief in the TA5F Latchlock. Screw the TA5F Flex Relief onto the TA5F Latchlock. 6) If needed, position and shrink the 1/8-inch shrink tub-

Microphone RF Bypassing When used on a wireless transmitter, the microphone element is in the proximity of the RF coming from the transmitter. The nature of electret microphones makes them sensitive to RF, which can cause problems with the microphone/transmitter compatibility. If the electret microphone is not designed properly for use with wire-

less transmitters, it may be necessary to install a chip capacitor in the mic capsule or connector to block the RF from entering the electret capsule. Some mics require RF protection to keep the radio signal from affecting the capsule, even though the transmitter input circuitry is already RF bypassed (see schematic diagram). If the mic is wired as directed, and you are having dif-

ficulty with squealing, high noise, or poor frequency response, RF is likely to be the cause. The best RF protection is accomplished by installing RF bypass capacitors at the mic capsule. If this is not pos-

sible, or if you are still having problems, capacitors can be installed on the mic pins inside the TA5F connector housing. 12 2 WIRE MIC 3 WIRE MIC Preferred locations for bypass capacitors SHIELD AUDIO SHIELD AUDIO BIAS CAPSULE TA5F CONNECTOR CAPSULE Alternate locations for bypass capacitors TA5F CONNECTOR Install the capacitors as follows: Use 330 pF capaci-

Silver Paste on SM Series Transmitter Thumbscrews Silver paste is applied to thumbscrew threads on new units at the factory to improve the electrical connection from the battery compartment through the housing on any SM Series transmitter. This applies to the standard battery door and the battery eliminator. Simply hold the cloth around the threads and turn the thumbscrew. Move to a new spot on the cloth and do it again. Do this until the cloth remains clean. Now, clean the threads in the case by using a dry cotton swab (Q-

tip) or equivalent. Again, clean the case threads until a fresh cotton swab comes away clean. Open the vial, and transfer a pinhead speck of silver paste to the second thread from the end of the thumb-

screw. A easy way to pickup a speck of paste is to partially unfold a paper clip and use the end of the wire to acquire a tiny bit of paste. A toothpick will also work. An amount that covers the end of the wire is sufficient. Apply paste to second thread from end of thumbscrew Threads provide electrical contact The small enclosed vial contains a tiny amount (25 mg) of silver conductive paste. A small speck of this paste will improve the conductivity between the battery cover plate thumbscrew and the case of the SM. The tiny vial is about 1/2 inch tall and contains 25 mg of silver paste. It is not necessary to spread the paste more than a little bit on the thread as the paste will spread itself every time the thumbscrew is screwed in and out of the case during battery changes. Do not apply the paste to any other surfaces. The cover plate itself can be cleaned with a clean cloth by rubbing the slightly raised rings on the plate where it contacts the battery terminal. All you want to do is to remove any oils or dirt on the rings. Do not abrade these surfaces with a harsh material such as a pencil eraser, emery paper, etc., as this will remove the conductive nickel plating and expose the underlying aluminum, which is a poor contact conductor. With improved conductivity (lower resistance), more of the battery voltage can get to the internal power sup-

plies causing reduced current drain and longer battery life. Though the amount seems very small, it is enough for years of use. It is, in fact, 25 times the amount that we use on the thumbscrews at the factory. To apply the silver paste, first completely remove the cover plate from the SM housing by backing the thumb-

screw completely out of the case. Use a clean, soft cloth to clean the threads of the thumbscrew. NOTE: Do NOT use alcohol or a liquid cleaner. 15 Android LectroRM is a mobile application for iOS and Android operating systems. Its purpose is to remotely control Lectrosonics Transmitters, including:

LectroRM By New Endian LLC SM Series WM L Series The app remotely changes settings on the transmitter through the use of encoded audio tones, which when received by the attached microphone, will alter the configured setting. The app was released by New En-

dian, LLC in September 2011. The app is available for download and sells for $25 on the Apple App Store and Google Play Store. LectroRMs remote control mechanism is the use of an audio sequence of tones (dweedles) that are inter-

preted by the transmitter as a configuration change. The settings available in LectroRM are:

Audio Level Frequency Sleep Mode Lock Mode User Interface The user interface involves selecting the audio se-

quence related to the desired change. Each version has an interface for selecting the desired setting and the desired option for that setting. Each version also has a mechanism to prevent accidental activation of the tone. iOS The Android version keeps all settings on the same page and allows the user to toggle between the activa-

tion buttons for each setting. The activation button must be long pressed to activate. The Android version also allows users to keep a configurable list of full sets of settings. Activation For a transmitter to respond to remote control audio tones, the transmitter must meet certain requirements:

The transmitter must not be turned off; it can however be in sleep mode. The transmitter must have firmware version 1.5 or later for Audio, Frequency, Sleep and Lock changes. The transmitter microphone must be within range. The transmitter must be configured to enable remote control activation. Please be aware this app is not a Lectrosonics product. It is privately owned and operated by New Endian LLC, www.newendian.com. The iPhone version keeps each available setting on a separate page with the list of options for that setting. On iOS, the Activate toggle switch must be enabled to show the button which will then activate the audio. The iOS versions default orientation is upside-down but can be configured to orient right-side up. The purpose for this is to orient the devices speaker, which is at the bot-

tom of the device, closer to the transmitter microphone. 16 Straight Whip Antennas This is a full size cutting template used to cut the length of the whip for a particular frequency. Lay the uncut antenna on top of this drawing and trim the whip length to the desired frequency. After cutting the antenna to the desired length, mark the antenna by installing a color cap or sleeve to indicate the color listed in the table below Whip Length The supplied caps can be used several different ways:

1) A color cap on the end of the whip 2) A color sleeve next to the connector with a black cap on the end of the whip (trim the closed end of the colored cap off with scissors to make a sleeve). 3) A color sleeve and color cap (cut the cap in half with scissors). 4 4 9 9 2 8 2 7 2 6 2 5 2 4 2 3 2 2 2 1 2 0 2 9 1 0 7 4 Note: Check the scale of your printout.

It is important that you follow these steps in the sequence listed. SYMPTOM POSSIBLE CAUSE TRANSMITTER PWR LED OFF 1) Battery is inserted backwards or dead. 2) Transmitter not powered up. (See Operating Instructions, Power UP and Boot Sequence.) TRANSMITTER PWR LED BLINKS GREEN EVERY FEW SECONDS, TRANSMITTER DOES NOT RESPOND OTHERWISE 1) Transmitter has been put to sleep by the remote control. Either use the remote control to wake it up again or remove and reinsert the transmitters battery. AUDIO LEVEL LEDs NOT LIGHTING 1) Gain control set to minimum. 2) Battery is dead or installed backwards. Check PWR LED. 3) Mic capsule is damaged or malfunctioning. 4) Mic cable damaged or mis-wired. RECEIVER RF INDICATOR OFF 1) Transmitter not turned on, or is in Standby Mode. 2) Transmitter battery is dead. NO SOUND (OR LOW SOUND LEVEL), RECEIVER INDICATES PROPER AUDIO MODULATION DISTORTED SOUND 3) Receiver antenna missing or improperly positioned. 4) Transmitter and receiver not on same frequency. Check switches/display on transmitter and receiver. 5) Transmitter and receiver not on same frequency block. 6) Operating range is too great. 7) Defective transmitter antenna. 1) Receiver output level set too low. 2) Receiver output disconnected, or cable defective or mis-wired. 3) Sound system or recorder input is turned down. 1) Transmitter gain (audio level) is far too high. Check audio level LEDs and receiver audio levels during use. 2) Receiver output may be mismatched with the sound system or recorder input. Adjust output level on receiver to the correct level for the recorder, mixer or sound system. (Use the receivers Tone function to check level.) 3) Transmitter is not set to same frequency as receiver. Check that operating frequency on receiver and transmitter match. 4) Receiver/Transmitter Compatibility Mode mismatched. EXCESSIVE FEEDBACK 1) Transmitter gain (audio level) too high. Check gain adjustment and/or reduce receiver output level. 2) Talent standing too close to speaker system. 3) Mic is too far from users mouth. 20 SYMPTOM POSSIBLE CAUSE HISS AND NOISE -- AUDIBLE DROPOUTS 1) Transmitter gain (audio level) far too low. 2) Receiver antenna missing or obstructed. 3) Transmitter antenna broken or missing. 4) Operating range too great. 5) Signal interference. Turn off transmitter. If receivers signal strength indicator does not drop to nearly zero, this indicates an interfering signal may be the problem. Try a different operating frequency. Loc APPEARS IN DISPLAY WHEN ANY BUTTON IS PRESSED 1) Control Panel is locked. (See Operating Instructions, Locking and Unlocking the Control Panel.) Hold APPEARS IN DISPLAY WHEN ARROW BUTTONS ARE PRESSED 1) Reminder that it is necessary to hold down the AUDIO or FREQ button to make adjustments to the audio gain or frequency settings. PLL APPEARS IN DISPLAY 1) Indication that the PLL is not locked. This is a serious condition that requires factory repair. It may be possible to operate on another frequency far removed from the one that was selected when the condition was indicated. TRANSMITTER WONT RESPOND TO REMOTE CONTROL 1) If LCD blinks rc oFF, transmitter has not been configured to respond to the remote control. See Remote Control Operation on page 7 for instructions on how to configure. 2) If LCD blinks - - - - - -, transmitter is already set as requested by the remote control. 3) If transmitter does not respond at all, try moving the remote control closer to the microphone or increasing the remote controls loudness setting, or increasing the audio level on the transmitter. 4) Make sure volume of RM and proximity of microphone are sufficient to engage transmitter. 5) Make sure transmitter is not in Sleep mode. 21 Specifications and Features Operating frequencies:

22 Service and Repair If your system malfunctions, you should attempt to correct or isolate the trouble before concluding that the equipment needs repair. Make sure you have followed the setup procedure and operating instructions. Check the interconnecting cables and then go through the Troubleshooting section in this manual. We strongly recommend that you do not try to repair the equipment yourself and do not have the local repair shop at-

tempt anything other than the simplest repair. If the repair is more complicated than a broken wire or loose connection, send the unit to the factory for repair and service. Dont attempt to adjust any controls inside the units. Once set at the factory, the various controls and trimmers do not drift with age or vibration and never require readjustment. There are no adjustments inside that will make a malfunctioning unit start working. LECTROSONICS Service Department is equipped and staffed to quickly repair your equipment. In warranty repairs are made at no charge in accordance with the terms of the warranty. Out-of-warranty repairs are charged at a modest flat rate plus parts and shipping. Since it takes almost as much time and effort to determine what is wrong as it does to make the repair, there is a charge for an exact quotation. We will be happy to quote approximate charges by phone for out-of-warranty repairs. Returning Units for Repair For timely service, please follow the steps below:

A. DO NOT return equipment to the factory for repair without first contacting us by email or by phone. We need to know the nature of the problem, the model number and the serial number of the equipment. We also need a phone number where you can be reached 8 A.M. to 4 P.M. (U.S. Mountain Standard Time). B. After receiving your request, we will issue you a return authorization number (R.A.). This number will help speed your repair through our receiving and repair departments. The return authorization number must be clearly shown on the outside of the shipping container. C. Pack the equipment carefully and ship to us, shipping costs prepaid. If necessary, we can provide you with the proper packing materials. UPS is usually the best way to ship the units. Heavy units should be double-boxed for safe transport. D. We also strongly recommend that you insure the equipment, since we cannot be responsible for loss of or dam-

age to equipment that you ship. Of course, we insure the equipment when we ship it back to you. Lectrosonics USA:
