CHAPTER 2 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 automobiles, the transceiver is usually mounted below the dash panel with the microphone bracket beside it. MOUNTING THE RADIO The transceiver is supplied with a universal mounting bracket. When mounting the bracket and radio to your car, make sure it is mechanically strong.
Before installing the transceiver in a boat, consult your dealer for information regarding an adequate grounding system and prevention of electrolysis between fittings in the hull and water. TUNING THE ANTENNA FOR OPTIMUM SWR Since there is such a wide variety of base and mobile antennas, this section will strictly concern itself to the various types of mobile adjustable antennas.
CHAPTER 3 OPERATION FRONT PANEL 5. TALKBACK CONTROL : This control is used to adjust the desired volume of Talkback. This is used to monitor your own voice. For example, you could use this feature to compare different microphone. 6. MIC GAIN CONTROL : Adjusts the microphone gain in the transmit and PA modes. This controls the gain to the extent that full talk power is available several inches away from the microphone. In the Public Address (PA) mode, the control functions as the volume control. 7.
14. CB/PA SWITCH : Selects the mode of operation. In the PA position, the transceiver acts as a public address amplifier. Before operating in the PA mode, you must first connect an external PA speaker to the PA jack on the rear panel. In the CB mode, the PA function is disabled. REAR PANEL 15. TONE HI/LO SWITCH : This switch shapes audio response. In the LO position, the base is increased and in the HI position, the treble is increased. 16.

3. If the channel is clear, depress the push-to-talk switch on the microphone and speak in a normal voice. RECEIVING SSB SIGNALS There are three types of signals presently used for communications in the Citizens Band : AM, USB, LSB. When the MODE switch on your unit is placed in the AM position, only standard double-sideband, full carrier signals will be detected.
ALTERNATE MICROPHONES AND INSTALLATION For best results, the user should select a low-impedance dynamic type microphone or a transistorized microphone. Transistorized type microphones have a low output impedance characteristics. The microphones must be provided with a five-lead cable. The audio conductor and its shielded lead comprise two of the leads. The third lead is for receive control, the forth is for grounding and fifth is for transmit control. 2. All leads should be cut to the same length.
5. The wires must now be soldered to the pins as indicated in the above wiring tables. If a vise or clamping tool is available it should be used to hold the pin receptacle body during the soldering operation, so that both hands are free to perform the soldering. If a vise or clamping tool is not available, the pin receptacle body can be held in a stationary position by inserting it into the microphone jack on the front panel.
8. Provide "local information" to find your destination. 9. Help law enforcement officers by reporting drunk and reckless drivers. A FEW RULES THAT SHOULD BE OBEYED 1. 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. 2. You are not allowed to blast others off the air by over-powering them with illegally amplified transmitter power, or illegally high antennas.
