iii WARNING!

RF RADIATION EXPOSURE HAZARD This warning is provided by Broadcast Microwave Services (BMS) Inc. for safety purpose. The following information help to reduce the risk of RF exposure hazard. FCC Limit of RF Exposure According to Federal Communication Commission (FCC), the Maximum Permissible Exposure (MPE) for FR radiation has been set to 1.0 mW/cm2 for the 6 GHz Carry-

Coder II with 190 mW output power (OET Bulletin 65). The 6 GHz Carry-Coder II is a non-broadcast transmitter and without an antenna it will not create RF exposure (power density) exceeding the 1.0 W/cm2 FCC limit. However a high-gain antenna such as a parabolic dish will greatly enhance the 6 GHz Carry-Coder II output power density beyond the MPE limit of 1.0 mW/cm2. In this situation a minimum distance from the antenna needs to be calculated in order to keep the MPE always below the safety limit. The calculation has been done for 6 GHz Carry-Coder II based on the formula mentioned in OET Bulletin 56. The calculations have been done for different commonly used antenna in the Public Safety/ Law enforcement applications. Figure 1 shows the plot of the minimum exposure distance for 5dBi, 16dBi, and 30dBi antennas. The 6 GHz Carry-Coder II transmits the maximum power of 190 mW. The minimum exposure distances are found from the cross points of the exposure graphs

(for various antennas) with the line of maximum permissible exposure (i.e. 1 W/cm2). Notice that the numbers in Figure 1 predict the worse case scenario, which is straight in front of the antenna (exposing to the antenna main-lobe). Obviously the side-lobe exposures are well below these numbers as the radiation intensity dramatically reduces on the side lobes.

"The antenna used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter."

4 GETTING STARTED Installing the Transmitter on the Backpack Orient the CCII so that it will mount onto the backpack with the Antenna facing up. Align the three mounting pins on the back of the CCII with the receptacles on the backpack. Slide the CCII into to the receptacle until it is locked in place. No orange will show from under the latch. Use the belt to further secure the CCII in place. Carefully attach the BMS supplied antenna with integrated extension shaft to the antenna connector on the top of the CARRY-CODER II. This antenna extension shaft ensures that the transmitted signal is sent out into unobstructed space for propagation of the COFDM signal. In addition this shaft ensures the safety of the operator in accordance to FCC and CE safe emissions requirements. Connect the interface cables from the camera to the appropriate CARRY-CODER II connector(s). Installing the Battery on the Backpack Slide the battery in to the receptacle located underneath the CCII until it locks into place Connect the power cable coming from the backpack battery connector socket to the CARRY-CODER II. Switch on the power for the camera and the CARRY-CODER II. When the CARRY-CODER II is used in the camera mount or the backpack configuration the system must be used with the BMS supplied antenna that has an integrated shielded antenna extender in order to meet FCC and CE safe emissions requirements. Please note that the CARRY-CODER II can be powered from an external supply source (i.e., a battery belt or the backpack battery) instead of an attached battery. For this purpose, the CARRY-CODER II provides a separate power connector and a switch to select the docked battery or a separate DC power source. The benefit provided by using the backpack is the efficient use of individual batteries, obtaining optimal battery life. 6051412900 Rev -

5 Controlling the CARRY-CODER II Transmitter Control Unit Features The CARRY-CODER II control unit is designed for the convenience of the user. The control unit can be attached or disconnected at any time. Easily readable four line display. Operator navigation of menu with four intuitive directional buttons. Operational command entry using the <OK> button. Display includes status icons at right portion of top line. Text menu line one displays operating frequency. Text menu lines two and three are for system control functions. Text menu line four displays system status. Transmitter Operating Configuration When the CARRY-CODER II is powered up for the first time, the operator can easily review the operating parameters using the control unit. Here is a listing of the parameters, in operating menu sequence. RF Output Operating Frequency (.25 or .5 MHz Steps depending on Frequency or BAS Band Channel with Operating Frequency). Transmission Mode Robustness (LOW MID HIGH). RF Output Power (OFF LOW MID HIGH MAX). Recall Configuration (Presets 1 to 9). Save Configuration (Presets 1 to 9). Video Input (CVBS, YUV, ASI, SDI). Video Mode (PAL, NTSC). Audio Input (analog, AES, SDI). Audio Level Left Audio Level Right Data Port Baud Rate (1.2, 4.8, 9.6 Kbps) Encryption (OFF or PIN code entry). User Mode (NORMAL, EXPERT) PLEASE THOROUGHLY REVIEW SECTION 0 BEFORE USING <EXPERT> Mode. 6051412900 Rev -

6 CARRY-CODER II Transmitter <EXPERT> Operating Mode Configuration NOTE: Most users will operate the system in <NORMAL> mode. The <EXPERT> mode provides user control of certain DVB-T parameter settings. Here is a listing of those parameters in operating menu sequence:

Resolution (1/1, 3/4, 2/3, 1/2) GOP Structure (I, IP, IBP, IBBP, 422IBBP) GOP Length (6, 12, 18, 24) Constellation (QPSK, 16QAM, 64QAM) Guard Interval (1/32, 1/16, 1/8, 1/4) Code Rate (1/2, 2/3, 3/4, 5/6, 7/8) Please refer to Section 4.6 for a table describing how these DVB-T parameters are applied to the three factory presets for signal robustness. Section 0 contains operating instructions for using the EXPERT mode. Certain operating parameters are used on a repeated basis. These settings should be stored in memory as Configuration Presets 2 through 9. This provides fast restoration of parameter settings that are used most often. A good backup plan is to maintain commonly used parameter settings (i.e., high robustness and maximum power) in a known configuration preset memory. If a problem occurs that wont go away, a known good parameter setting can be recalled from memory. This should help to resolve a problem. Another method is to adjust each parameter one by one, beginning with changing the operating frequency, to ensure that the link is not being affected by another signal on your selected operating frequency. The <DEFAULT> option in the RECALL CONFIGURATION Menu will set all the parameters of the CCII to the factory defaults. 6051412900 Rev -

8 OPERATING INSTRUCTIONS Start-Up Indications The CARRY-CODER starts with display showing the status of the system During system initialization, the CARRY-CODER II goes through self-test of its MPEG-2 encoder, COFDM modulator and RF sections. System initialization 10 seconds and will display as follows:

BMS Inc. CarryCoder 2 Freq Agile 6425 6526 MHz Software Ver. 2.01 Resetting /

At the completion of the initialization process, the display should look like this:

If the self-test finds that a sub-system does not respond correctly, a status message is displayed on the fourth line of the display. For example, if the camera is not sending video to the transmitter, the display will include the appropriate message:

6431.25 MHz FREQUENCY 6431.25 MHz 6431.25 MHz FREQUENCY 6431.25 MHz NO VIDEO When the CARRY-CODER starts up, it is in the same condition as when it was powered down. This allows the user to replace the battery with no need to touch the controls. The CARRY-CODER II will not transmit with out video. If the System is powered up without video, the CARRY-

CODER II will automatically reboot once video input starts. The CARRY-CODER II will transmit with ASI. Operator Menu Summary When the control panel display shows normal system status (no Error or Warning status message) and if there is no operator use of the control panel, the display goes dark to save battery life. Pressing any key on the control unit restores the display to show the status of the system. If there is a status message, the display will remain lit (will not go dark) until the problem is resolved. The user menus can be accessed from the status screen by pressing any key. Then, the user can scroll the menus by pressing the

and keys. After 30 seconds of keypad inactivity, the display automatically returns to the status screen. Pressing the and keys simultaneously will cause the display to go to the status screen without having to wait 30 seconds. 6051412900 Rev -

RF OUTPUT POWER OFF LOW MID HIGH MAX The cursor (underscore) shows that the transmitter output is switched off. The operator can change the current condition (displayed line 3) by using the Left Arrow < > or Right Arrow < > keys, moving the cursor under the desired transmit output power level, followed by pressing the < OK > key to accept the chosen parameter. If the user doesnt confirm his choice by pressing the < OK >

key, or uses the Up Arrow < > or Down Arrow < > keys, the operating parameter change is cancelled; the current parameter is not modified. This is a convenient escape feature. Certain operating parameters are entered values (not selected values). For example, the frequency is displayed as follows:

To change the current value of this parameter, the operator presses < OK >, entering the Menu Edit mode, so the cursor appears under the first figure of the displayed frequency, as follows:

The frequency value is changed by the following steps: (1) move the cursor to the appropriate figure using the < > and < >

keys; (2) increment or decrement the selected figure using the < > and < > keys. For example:

The frequency value to the right of the decimal point is a fractional MHz value, selected in steps of 250 KHz (.25 MHz). Repeat the operation (previously described) to increment or decrement this value. To increment to a frequency of 2450.50 MHz, move the cursor to the right of the decimal point, then press the < > one time:

After modifying all of the necessary digits, the operator must validate the chosen frequency by pressing < OK > and closing the Menu Edit mode, changing the operating frequency. FREQUENCY 6434.50 MHz FREQUENCY 6434.50 MHz FREQUENCY 6434.50 MHz FREQUENCY 6454.50 MHz FREQUENCY 6454.25 MHz If you make a mistake while setting a number and you want to restore the previous value, dont validate your modifications: simply wait during 30 seconds without touching the keypad. The system will automatically exit the edit mode without saving the modifications; the display returns to the status screen. 6051412900 Rev -

12 Setting Transmitter Operating Frequency CARRY-CODER II Using Direct Frequency Entry The RF frequency is set as follows:

6454.25 MHz FREQUENCY 2454.25 MHz The frequency display is expressed in MHz with 250 kHz tuning steps. The frequency value corresponds to the center of the 8 MHz RF channel that is used for transmission. If the user tries to enter a value which is not in the operating frequency range, an Out of range message is displayed and the current frequency value is not changed. CARRY-CODER II for Broadcast The RF operating frequency is set using the channel plan with frequency offset. CH 3- 2029.25 MHz FREQUENCY 2029.25 MHz Versions of the CARRY-CODER II are available for several dedicated operating frequency ranges.

13 Setting Transmitter Output Power The RF power is set through the following menu:

RF OUTPUT POWER off low mid high max The following table gives the RF power (real average COFDM power) corresponding to each setting, accompanied by the resulting power supply consumption. (2 GHz shown) Choice OFF LOW MID HIGH MAX RF Power Muted 25 mW 50 mW 100 mW 250 W Power Consumption Low (about 30 W) Low (about 30 W) Low (about 30 W) Normal (about 40 W) Normal (about 40 W) When the CARRY-CODER II is close to the receiving antenna (< 25m) you can try to reduce the RF output power to MIN or MID level. It saves the batteries and can improve reception (avoiding receiver overload). Setting Transmission Mode and Robustness The CARRY-CODER II includes 3 pre-defined modes, characterized by defined transmission robustness. These 3 pre-defined modes have been configured to provide the best trade-off between transmission robustness, video quality and end-to-end delay for typical applications of the CARRY-CODER. These modes can be selected through the following menu:

ROBUSTNESS low mid high expert The detailed characteristics of these modes are:

Select < HIGH > mode then press < OK >

2. Wait for the system to re-initialize then press < OK > once again. Selecting EXPERT will not change any current settings. It will bring up the EXPERT Mode Menus. The following table suggests which factory defined robustness mode to use for certain applications. 6051412900 Rev -

13 Mode (TX Robustness) LOW Preferred applications Studio MID HIGH News, sports, entertainment Mobile & airborne transmission (with walls or buildings in the path) Characteristics Short transmission range. Maximum video quality. Medium transmission range. High video quality. Long and/or difficult transmission. Normal video quality. The operator can define specific operating parameters (compression and transmission) via the EXPERT mode. See section 0 Recalling and Saving Operating Configurations The CARRY-CODER II provides the operator with the ability to save and recall 8 user-defined presets configurations. These configurations are non-volatile (saved in an EEPROM) and are not lost when the system power is switched off. Each configuration contains all of the CARRY-CODER operating parameters, so that recalling a user-defined configuration will restore the system exactly in the same state as when it was saved. Preset (stored) configurations are recalled using the following menu:

RECALL CONFIGURATION 1 2 3 4 5 6 7 8 9 default To recall a configuration the user should select one of the preset memories or default then press < OK >. Selecting the <default> will reset all settings back to the factory default. Custom configurations are saved to memory using the following menu:

SAVE CONFIGURATION 1 2 3 4 5 6 7 8 9 To save a configuration the user should first set the appropriate operating parameters to the desired state, then select one of the preset (configuration) memories locations. In the following example, preset memory 2 is selected. Then, press < OK > to save the configuration to the selected preset (memory): The Menu Edit mode is completed. SAVE CONFIGURATION 1 2 3 4 5 6 7 8 9 SAVE CONFIGURATION 1 2 3 4 5 6 7 8 9

. Be careful when recalling configurations: If a preset configuration includes RF OUTPUT POWER active, the CARRY-

CODER II finishes its initialization and transmits on the RF frequency that is saved in memory! In order to follow accepted practice and to avoid unwanted transmission, good practice recommends that the preset configurations are saved with the <RF Output Power> setting in the < OFF > condition. Setting Video Input Parameters and Video Mode The video input type is set through the following menu. VIDEO INPUT CVBS YUV SDI ASI 6051412900 Rev -

14 If there is no signal on the selected input, the CARRY-CODER II displays a No video warning message and will not transmit. The operator can choose:

CVBS : Composite Video Baseband Signal YUV : Component video SDI: Serial Digital Video ASI: Transport The video input standard is set through the following menu. VIDEO MODE PAL NTSC The user can choose between:

PAL (625 lines, 50 Hz) NTSC (525 lines, 60 Hz) Setting Audio Input Parameters and Audio Level The audio input mode is set through the following menu:

AUDIO INPUT analog SDI Operator choice includes:

ANALOG: analog audio (line level) SDI:

AUDIO LEVEL LEFT

+ 3 dBu AUDIO LEVEL RIGHT

- 6 dBu The Operator can adjust the left and right audio level from 10 dBu to +4 dBu, via the following menus:

For instance, setting a value of 6 dBu means that the CARRY-CODER II is adjusted for a nominal input level of -6 dBu. This ensures headroom for A:D (analog-to-digital) conversion of approximately 18 dBFs (relative to full scale). When the nominal audio input level is below the value that is set, the system will operate correctly, but the signal-to-noise ratio will be degraded and the nominal audio output level on the receiving side will, in like manner, be low. If the nominal audio input level exceeds the set value, expect digital clipping to occur. If the nominal audio input level exceeds the absolute maximum value of +4 dBu, the audio signal will be heavily clipped and there will be significant loss of audio quality. Configuring Data Input (RS-232) The CARRY-CODER II provides an RS-232 input port that can be used for asynchronous user data transmission (i.e. for sending the transmitters GPS-derived location data to a receiver tracking antenna system). The RS-232 input is configured through the following menu:

DATA PORT BAUD RATE 1.2 4.8 9.6 6051412900 Rev -

15 Configuring Transmission Privacy The CARRY-CODER II offers the choice of encrypting the transmitted signal in order to ensure the privacy of the link. This feature is controlled through the following menu:

ENCRYPTION OFF ENTER PIN This operation uses a 6 digit encryption code. Both the transmitter and the receiver must have the same PIN encryption code in memory. If not, the DC II receiver will indicate <BAD ENCRYPTION>. The receiver will demodulate the signal, but it will not provide valid audio, video or data outputs. Once an encryption code is stored, the operator cannot read the setting of the code: if the code is not on record, the operator must change to a new encryption code or set Encryption to < OFF >. To activate signal encryption, the operator selects this menu function then presses < OK > to enter the Menu Edit mode. Move the cursor to ENTER PIN. Press < OK >. The digits available for the CARRY-CODER II encryption code are 0-9, and A-F. The PIN code is only visible when you enter it. If you forget the PIN code of one device, the simplest solution is to enter a new PIN code for both the transmitter and the receiver. All six digits set to < 0 > result in no encryption. The (first generation) CARRY-CODER I (CC I) and the DE-CODER I (DC I) receiver use four digit PIN encryption of 0-9. When the CARRY-CODER II transmitter is used with the DE-CODER I receiver, the CARRY-CODER II encryption is compatible if the PIN encryption setting has the first two PIN digits set to <0> (i.e., PIN setting <001234> on the CC II or DC II will work with PIN setting

<1234> on the CC I or the DC I>. Any letters used in a CCII encryption code will be interpreted as 0 by the CCI or DCI systems. 6051412900 Rev -

16 USING EXPERT MODE The CARRY-CODER II has two modes of operation. transmission parameters. The expert mode is activated through the following menu:

USER MODE normal expert 1. The NORMAL mode provides the operator with control of system functions that are needed in routine portable camera situations. Section 3 of this manual describes these functions, including three factory preset configurations. 2. The EXPERT mode enables the operator to selectively adjust key (audio and video) compression and COFDM The EXPERT mode should be used carefully because specific parameter settings are required to ensure proper operation of the system. This mode should be reserved to advanced users. The Expert Mode gives access to the expert audio-video and COFDM parameters that are described in the next sections. Expert Video Parameters Recommendations The video quality mainly depends upon the allocated video bit rate and is closely linked to picture resolution and Group Of Picture

(GOP) structure. The following table describes recommendations for realistic combinations for video encoding parameters. Video Bit Rate GOP structure Video quality 2-3 Mb/s 3-5 Mb/s 5-8 Mb/s 8-11 Mb/s 11-15 Mb/s IBBP IBBP IBBP IP I Poor Medium High High Maximum Typical end-to-end Delay Approximately 260 ms. Approximately 260 ms. Approximately 260 ms. Approximately 130 ms. Approximately 80 ms. Other combinations can be derived by the operator using the expert video parameters that are described below:

If the video bit rate selected exceeds the current available bit rate, the CCII will automatically scaled down the bit rate. Video Bitrate Video bitrate 4.35 Mbps This parameter controls digital picture resolution (pixels per line) used for MPEG-2 encoding. A high MPEG-2 encoding Bit rate provides greater resolution for the best video quality. A low MPEG-2 encoding Bit rate provides lower resolution, reducing the quality of the picture. Decreasing the resolution setting is useful for a low encoding Bit rate in order to reduce Pixelization when dealing with highly detailed fast moving scenes. 6051412900 Rev -

17 GOP Structure GOP STRUCTURE I IP IBP IBBP 422IBBP GOP Length GOP LENGTH 6 12 18 24 This parameter controls the structure of picture groups used in the MPEG-2 encoding process. These groups are based on three possible picture types:

I: Intra-frames (completely encoded). P: Predicted-frames (using motion estimation). B: Bi-directionally estimated frames (using motion estimation). This parameter has a direct affect on video encoding delay. For a given Bit rate:

IBBP and IBP frame modes offer good video quality in difficult transmission conditions. IP frame mode offers a good compromise between video quality and near-line-of-sight conditions. I-frame mode offers the same encoding delay as IP mode, with high Bit rates to ensure the greatest video quality. This is a secondary parameter involving a trade-off between video encoding efficiency and transmission error tolerance. A high value slightly improves the video quality at the expense of an increased worst-case recovery time required by the MPEG2 decoder when a transmission error occurs. The value is expressed in terms of full frame pictures. The typical value is 12. Expert COFDM Parameters You can find some information about COFDM modes characteristics in Annex A. The COFDM mode is controlled by adjusting certain COFDM parameters, described below. Constellation CONSTELLATION QPSK 16QAM 64QAM This represents the constellation scheme that is used to individually modulate each sub-carrier of the COFDM signal. The Constellation can be set to optimize robustness but also affects the data transmission rates. QPSK will provide the greatest robustness but lowest data rates. 16QAM is somewhat robust with a faster data rate. 64QAM will provide the least robust signal, but at the fastest data rate. The characteristics corresponding to the 3 possible choices are summarized in this table:

18 Guard Interval GUARD INTERVAL 1/32 1/16 1/8 1/4 CODE RATE 1/2 2/3 3/4 5/6 7/8 The Guard Interval corresponds to the idle time that exists between each COFDM symbols, in order to avoid inter-symbol interference in a Multipath environment. The Guard Interval helps prevent the receiver from being affected by signal echo interference by allowing time for echoes to settle before the active symbol is sent. Guard Interval is expressed as the ratio of the idle time divided by the useful part of the COFDM symbol. Code Rate The Code Rate represents the ratio of signal to error correction. The Code Rate is related to the quantity of redundancy bits that are added for error correction. The code rate is expressed as the ratio of the useful bitrate divided by the total bitrate (including redundancy bits). Channel Bandwidth Channel Bandwidth 8 7 6 Mhz The CCII is capable of 3 channel bandwidth settings. Serial Address Serial Address 6 Encryption Type Encryption Type A B For the typical application, the CCII is controlled by the Handheld Controller (BMS P/N 8014154000) and there is no reason to configure the serial address. However, It is possible to control the CCII with another external device via the DB15 connector. In that case, the serial address will need to be configured to match the device used. When used in an BMS HCII system, the CCII Serial Address must be set to 5 CCII uses a proprietary encryption scheme that will only work with BMS recieivers. The Encryption Type only matters when Encryption is in use. To use Encryption, a PIN must be set (see section 0). This PIN must match the Receiver PIN in order for the signal to be descrambled. Select the Encryption type based on the application. Type A is recommended encryption type and can be used for both Telecom or RF broadcast applications. Type B is for RF broadcast only under certain circumstances. 19 PMT PID PMT PID 200 PCR PID 101 Video PID 300 Audio PID 301 PIDs You can find some information about Tables and PIDs in Annex B. The contents of the Transport Stream are defined by information tables that describe the organization of the transmitted data in addition to the video and audio content. These tables along with video, audio and private user data are transmitted in packets. A Packet Identifier (PID) number is used to distinguish between packets. PIDs may have values from 0 to 8191. The CCII allows the following PIDs to be changed:

PMT (Program Map Table) PID PCR (Program Clock Recovery) PID Video PID Audio PID The PID value set on the CCII must match the PID value on the DCII or CDCII. Mismatched PIDs will result in no video or audio outputs. Program Map Table Packet Identifier yields information about the Program, Video PID, Audio PID, and PCR PID. The PMT PID default is 200 for BMS systems. PCR PID Program Clock Reference Packet Identifier default is 101 for BMS systems. Video PID The Video Packet Identifier default for the BMS systems is 300. Audio PID The Audio Packet Identifier default for the BMS systems set to 301. 6051412900 Rev -

25 ANNEX A: COFDM Modes Characteristics The main COFDM modulation parameters are:

Number of sub-carriers (1705) Guard interval (GI) duration between COFDM symbols Constellation scheme used for individual sub-carrier modulation Data redundancy code rate used for error correction The transmission robustness mainly depends on constellation scheme and code rate. The following table gives the useful transmission bit rate for each COFDM mode. It also specifies the Carrier-to-Noise operation limit in the case of a perfect line-of-sight (Gaussian) channel and in the case of a typical multipath terrestrial (Raylegh) channel. Useful Bitrate (Mb/s) GI=1/16 GI=1/32 C/N for perfect channel (dB) C/N for typical channel (dB) Constellation Scheme QPSK 16-QAM 64-QAM Code Rate 1/2 2/3 3/4 5/6 7/8 1/2 2/3 3/4 5/6 7/8 1/2 2/3 3/4 5/6 7/8 GI=1/4 4,98 6,64 7,46 8,29 8,71 9,95 13,27 14,93 16,59 17,42 14,93 19,91 22,39 24,88 26,13 GI=1/8 5,53 7,37 8,29 9,22 9,68 11,06 14,75 16,59 18,43 19,35 16,59 22,12 24,88 27,65 29,03 6,03 8,04 9,05 10,05 10,56 12,06 16,09 17,10 20,11 21,11 18,10 24,13 27,14 30,16 31,67 5,85 7,81 8,78 9,76 10,25 11,71 15,61 17,56 19,52 20,49 17,56 23,42 26,35 29,27 30,74 3.1 4.9 5.9 6.9 7.7 8.8 11.1 12.5 13.5 13.9 14.4 16.5 18.0 19.3 20.1 5.4 8.4 10.7 13.1 16.3 11.2 14.2 16.7 19.3 22.8 16.0 19.3 21.7 25.3 27.9 Selection may be compromised due to the distance between the transmitter and receiver sites. We can notice that a low code rate (= high data redundancy) is necessary to insure a good efficiency in multipath environment. The guard interval determines the maximum echoes length dispersion that the system can tolerate. From this figure, we can estimate the maximum transmission range that the system might offer for a typical terrestrial channel (with adequate RF power). The following table summarizes the results that come out from the 4 possible guard interval values:

Guard Interval Guard Interval Duration (us) Maximum echoes dispersion (km) Maximum transmission distance (km) Ratio 1/32 1/16 1/8 1/4 7 14 28 56 2.1 4.2 8.4 16.8 2-6 4-12 8-24 16-48 Maximum transmission distances can be increased when using directive antennas, but signal break-ups can nevertheless occur when long echoes occasionally enter the receiving antenna. 6051412900 Rev -
