Page 4: Chapter 2 Installation
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 drive or passengers in the automobiles, the transceiver is usually mounted the dash panel with the microphone bracket beside it. -
Page 5: Ignition Noise Interference
IGNITION NOISE INTERFERENCE Use of a mobile receiver at low signal levels is normally limited by the presence of electrical noise. The primary source of noise in automobile installation is from the generator and ignition system in the vehicle. Under most operating conditions, when signal level is adequate, the background noise does not present a serious problem. -
Page 6: Tuning The Antenna For Optimum Swr
TUNING THE ANTENNA FOR OPTIMUM S.W.R 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. Because the antenna length is directly related to the channel frequency, it must be tuned to resonate optimally on all channels of the transceiver. -
Page 7: External Speaker
If you’re having difficulties in adjusting your antenna, check the following: All doors must be closed when adjusting the antenna Make sure the antenna base is grounded. Check your coaxial cable routing (it may be pinched when routed into the car) Try a different location in your car (keeping in mind the radiation pattern you wish.) Is the antenna perfectly vertical? Try a different location in your neighborhood. -
Page 8: Chapter 3 Operation
CHAPTER 3 OPERATION FRONT PANEL 1. SQUELCH CONTROL : This switch is used to eliminate background noise being heard through the receiver which can be disturbing when no transmission are being heard through the received. To use this feature, turn the switch fully counterclockwise and then turn clockwise slowly until the background noise is just eliminated. - Page 9 6. TALKBACK/OFF CONTROL: Adjust this knob for desired volume of Talkback. This is used to monitor your own voice. Or example, you could use this feature to compare different microphones. 7. BAND SELECTOR : This band selector allow the user to select the desired band. 8.
- Page 10 18. ROGER BEEP : When this switch is placed in the ROGER BEEP position, the radio automatically transmits an audio tone at the end of your transmission. This indicates the end of your transmission so that people who are having trouble hearing you will know that you are done speaking.

REAR PANEL 1. ANTENNA : This jack accepts 50 ohms coaxial cable with a PL-259 type plug. 2. DC POWER : This accepts 13.8V DC power cable with built-in fuse. The power cord provided with the radio consist of a blue wire (negative) and a red wire (positive). -
Page 12: Procedure To Receive And Transmit
PROCEDURE TO RECEIVE AND TRANSMIT A. MICROPHONE The receiver and transmitter are controlled by the push-to-talk switch on the microphone. Press the switch and the transmitter is activated, release switch to receive. When transmitting, hold the microphone two inches from the mouth and speak clearly in a normal voice. -
Page 13: Receiving Ssb Signals
RECEIVING SSB SIGNALS There are four types of signals presently used for communications in the Citizens Band : FM, AM, USB and LSB. When the MODE switch on your unit is placed in the AM position, only standard double-side band and in FM position, only frequency deviation, full carrier signals will be detected. - Page 14 Once the desired SSB mode has been selected, frequency adjustment may be necessary in order to make the incoming signal intelligible. The FINE/COARSE control allows the operator to vary frequency above or below the exact frequency of the channel. If the sound of the incoming signal is high or low pitched, adjust the operation of the FINE/COARSE.

Page 15: Alternate Microphone And Installation
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 low output impedance characteristics. The microphones must be provided with a four-lead cable. The audio conductor and its shielded lead comprise two of the leads. The third lead is for transmit control and fourth is for receiving control. - Page 16 the connections. Keep the exposed wire lengths to a minimum to avoid shorting when the microphone plug is reassembled. Fig. 2 Microphone plug wiring To wire the microphone cable to the plug provided, proceed as follows : 1. Remove the retaining screw. 2.
- Page 17 back of the plug. Before soldering the wire to the pins, pre-tin the wire receptacle of each pin of the plug. Fig. 3 Microphone plug pin numbers viewed from rear of pin receptacle. 6. Be sure that the housing and the knurled ring of Figure 2 are pushed back onto the microphone cable before starting to solder.
