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 4 GHz Carry-Coder II with 1Watt Power Amp equipment (OET Bulletin 65). The 4 GHz Carry-Coder II with Power Amp 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 4 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 4 GHz Carry-Coder II with Power Amp 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 4 GHz Carry-
Coder II with Power Amp transmits the maximum power of 1Watt. 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.

Figure 3 Typical system of 4GHz Carry-Coder II with Power Amplifier Mobile and Fixed Platforms The system of Figure 3 can demonstrate both mobile and fixed applications. The transmitter part including the Carry-Coder II Transmitter, Power Amplifier and the video camera are all mounted inside a truck. An omni-directional antenna placed on the vehicle roof-top (without any obstruction) transmit uniformly in all azimuth directions. This allows the mobile transmitter to communicate with the Receive Site while the vehicle is moving freely. In the Receive Site the omni-directional antenna on the mast will receive the transmitter signal without any need for tracking. Because of low antenna gain (both on transmit and receive ends) the Power Amplifier will be crucial in order to boost the transmitter power and ensure the minimum practical range. When the Transmitter Unit is stationary (i.e. the vehicle is stalled for a while) then the tracking dish antenna in the Receive site will be able to track the transmitter and establish a line of site transmission. This is considered a fixed situation and the high gain of the dish antenna will increase the minimum range. In the fixed platform the transmitter antenna can be changed from omni to a tracking dish antenna.

Installation Procedure The 4GHz Carry-Coder II with Power Amplifier can be installed inside a vehicle such as a truck. The symbolic diagram of the installation is given in Figure 3. The installation procedure is as follows:
1. Install the omni-directional antenna on the vehicle roof-top using the brackets and instructions that are supplied in the accessory kit. Secure the Carry-Coder II transmitter and the Power Amplifier inside the truck. The two units may be one or 2 feet apart. To ensure sufficient ventilation, at least 3 clearance is recommended from each side of the units. 2. 3. Using N-type coaxial cable (about 3 feet long) connect the output of the Carry-Coder II transmitter to the input of the Power Amplifier. Using Coaxial cable and N to SMA adaptor, connect the output of the Power Amplifier to the SMA input port of the omni antenna. Using the special power cords connect the Transmitter and the Power Amplifier to the 12V DC voltage. Connect the interface cables from the camera to the appropriate CARRY-CODER II connector(s). Using the supplied Remote Control Display, set the Transmitter frequency, power, modulation scheme etc. as will be explained in the next section. Installing the Battery on the Carry-Coder II The Carry-Coder II can be run by its own battery as well. The procedure for battery installation is as follows:
Slide the battery in to the receptacle located underneath the CCII until it locks into place Connect the power cable coming from the battery connector socket to the CARRY-CODER II. Switch on the power for the camera and the CARRY-CODER II.

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.

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

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.

This power amplifier is used in conjunction with 4 GHz Carry-Coder II. Application Because the internal amplifier of the 4 GHz Carry-Coder II is only capable to provide 400 mW max. RF power, an external amplifier is needed to boost the transmitter power in order to compensate the path loss and ensure the acceptable Received Signal Level (RSL) at the destination. The BPA-1CC-4 will increase the RF power to the maximum 1W, without adding spurious and distortions to the transmitter output. The output of the power amplifier is directly connected to the 4 GHz transmitting antenna. Specification:
