INSTALLATION
If you're having difficulties in adjusting your antenna, check the following:
a.
All doors must be closed when adjusting the antenna
b. Make sure the antenna base is grounded.
c.
Check your coaxial cable routing (it may be pinched when routed into the car)
d. Try a different location in your car (keeping in mind the radiation pattern you wish.)
e.
Is the antenna perfectly vertical?
f.
Try a different location in your neighborhood. Stay away from large metal objects
when adjusting (metal telephone polls or light post, fences, etc.)
The transceiver will operate into an SWR of 2 to 1
indefinitely and sustain an SWR of 20 : 1 for a maximum
of 5 minutes at rated operating conditions.
EXTERNAL SPEAKER
The external speaker jack (EXT SP.) on the rear panel is used for remote receiver
monitoring. The external speaker should have 8 ohms impedance and be able to handle at
least 4 watts. When the external speaker is plugged in, the internal speaker is disconnected.
PUBLIC ADDRESS
To use the transceiver as a public address system, connect an external 8 ohms speaker (4
watts minimum) to the PA. SP. jack located on the rear panel. Direct speaker away from
the microphone to prevent acoustic feedback. Physical separation or isolation of the
microphone and speaker is important when operating the PA at high output levels.

OPERATION
A
FRONT PANEL
1. MICROPHONE JACK: Used to connect microphone for voice source.
2. MIC GAIN CONTROL: Adjust 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 function as
the volume control.
3. ON/OFF VOLUME CONTROL: This knob controls the volume and power to the
radio. To turn radio on, rotate the knob clockwise. Turning the knob further will
increase the volume of the receiver.
4. SQUELCH CONTROL: This switch is used to eliminate background noise being
heard through the receiver, which can be disturbing when no transmission is 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. Further
clockwise rotation will increase the threshold level, which a signal must overcome in
order to be heard. Only strong signal will be heard at a maximum clockwise setting.
