Installation Location Plan the location of the transceiver and microphone bracket before starting the installation. Select a location that is convenient for operation and does not interfere with the driver or passengers in the vehicle. In automobiles, the transceiver is usually mounted to the underneath of the dash panel, with the microphone bracket beside it.
Installation (Cont.) Installation(Cont.) CB Antenna Since the maximum allowable power output of the transmitter is limited by the FCC, the antenna is one important factor affecting transmission distance. Only a properly matched antenna system will allow maximum power transfer from the 50-ohm transmission line to the radiating element. In mobile installations (cars, trucks, boats, etc.), an antenna system that is non-directional should be used.
Operation Operation (Cont.) Controls and Indicators Refer to controls, indicators and connectors as illustrated below: 5. CB/PA Switch. Selects mode of operation. In the CB position, the PA function is disabled and the unit will transmit and receive on the selected channel. The PA function should not be used unless a PA speaker is connected. 6. S-RF/Power Meter. Shows relative transmitter RF output power and input signal strength when receiving.
Operation (Cont.) 2 Operation (Cont.) 1. 3 Operating Procedure to Receive Be sure that the power, antenna and microphone are properly connected before proceeding further. The CB/PA switch should be in the CB mode. The Channel 9/NOR Switch should be in the NOR mode. 2. Turn the radio ON by rotating the VOLUME CONTROL clockwise. 3.

Maintenance and Adjustment Appendix Your COBRA CB transceiver is specifically designed for the environment encountered in mobile installations. The use of all solid state circuitry and its light weight result in high reliability. Should a failure occur, however, review the following, then if necessary replace parts only with identical parts. Do not substitute. Refer to the schematic diagram and parts list.
Appendix (Cont.) 1. 2. 3. 4. 5. 6. • • • • • • • • • A Few Rules That Should Be Obeyed You are not allowed to carry on a conversation with another station for more than five minutes at a time without taking a one-minute break, to give others a chance to use the channel. You are not allowed to blast others off the air by overpowering them with illegally amplified transmitter power, or illegally high antennas. You can't use CB to promote illegal activities. You are not allowed to use profanity.
