Controls and operation
Front Panel
1. Microphone Connector
Connect the microphone to this connector and turn the connector ring to lock it.
2. Up Button
This button allows you to change the operating channel upwards.
3. Down Button
This button allows you to change the operating channel downwards.
4. SQUELCH Control
The SQUELCH control allows you to silence the receiver by cutting out the background noise when no
signals are being received. Turn the knob clockwise until the background noise is cut. Turn the knob counter
clockwise (SQUELCH opening) in order to listen to the weakest signals.
5. RF GAIN knob
The receiver gain is adjustable with the RF GAIN knob. This control should be fully clockwise most of the
time, however in the case of very strong signals from local stations the receiver sensitivity can be reduced by
turning the knob anti-clockwise.
6. ON/OFF/VOLUME Control
Use this knob to switch radio ON and OFF, as well as to adjust the receiver volume to the desired level. To
adjust the receiver volume when no signals are being received on the operating channel, open the
SQUELCH and then adjust the receiver volume using the background noise as a reference.
