EXTERNAL SPEAKER

The external speaker jack (EXT. SPK.) on the rear panel is used for remote receiver
monitoring. The external speaker should have 8 ohms impedance and be able to
handle 4 watts at least. When the external speaker is plugged in, the internal speaker is
disconnected.

OPERATION

CONTROLS AND INDICATORS

There are 8 controls and 4 indicators on the front panel of your transceiver.

FRONT PANEL

1. ON/OFF VOLUME (inner dual concentric). Turn clockwise to apply power to the
unit and to set the desired listening level. During normal CB operation, the VOLUME
control is used to adjust the output level obtained either at the transceiver speaker or
the external speaker, if used.
2. SQUELCH (outer dual concentric). This control is used to cut off or eliminate receiver
background noise in absence of an incoming signal. For maximum receiver sensitivity
it is desired that the control is adjusted only to the point where the receiver background
noise or ambient background noise is eliminated. Turn fully counterclock-wise then
slowly clockwise until the receiver noise disappears. Any signal to be received must
now be slightly stronger than the average received noise. Further clockwise rotation
will increase the threshold level which must be overcome by a signal in order to be
heard. Only strong signals will be heard at a maximum clockwise setting.
3. MIC GAIN (inner dual concentric). Adjust the microphone gain in the transmit
mode.
4. RF GAIN CONTROL (outer dual concentric). It reduces the gain of the RF amplifier
under strong signal conditions.
5. SWR CAL CONTROL (inner dual concentric). In order to achieve maximum radiated
power and the longest range, it is important that your antenna is in good conditions,
