INSTALLATION INSTALLATION A A IGNITION NOISE INTERFERENCE TUNING THE ANTENNA FOR OPTIMUM S.W.R. 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.

INSTALLATION A OPERATION FRONT PANEL A 4. If you’re having difficulties in adjusting your antenna, check the following: a. b. c. d. e. f. All doors must be closed when adjusting the antenna. Make sure the base of the antenna 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.

OPERATION OPERATION A A 7. PLAY/STOP SWITCH `/■: This Push Switch controls the play and stop function for the MP3 Player. 8. NEXT/FORWARD SWITCH ``|: This Push Switch has dual function; it is used for selecting or to skip to the next track from the Music List. In addition, this switch is used to scroll forward pictures from the USB stick or SD card. 9. ON/OFF VOLUME CONTROL: This knob controls the volume and power to the radio. To turn radio on, rotate the knob clockwise.

OPERATION OPERATION A A ALTERNATE MICROPHONES AND INSTALLATION PROCEDURE TO RECEIVE AND TRANSMIT A. MICROPHONE The receiver and transmitter are controlled by the push-to-talk switch on the microphone. Press the PTT switch, transmitter will be activated, release switch to receive. When transmitting, hold the microphone two inches from the mouth and speak clearly in a normal voice. This transceiver comes complete with a low impedance dynamic microphone. B. PROCEDURE TO RECEIVE 1.
PAGE 8
OPERATION A Before beginning the actual wiring, read carefully the circuit and wiring information provided with the microphone you select. Use the minimum heat required in soldering the connections. Keep the exposed wire lengths to a minimum to avoid shorting when the microphone plug is reassembled. OPERATION A 5. The wires must now be soldered to the pins as indicated in the above wiring tables.
PAGE 9
OPERATION OPERATION A 9. The two cable clamp retainer screws should now be tightened to secure the housing to the microphone cord. If the cutting directions have been carefully followed, the cable clamp should secure to the insulation jacket of the microphone cable. 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.
