FRONT PANEL DRAWING
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 be 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 (wtih car engine running). Any signal to be
received must now be slightly stronger than the average received noise.
Further clockwise rotation will increase the threshold level which a signal
must overcome in order to be heard. Only strong signals will be heard at a
maximum clockwise setting.
3. MIC BUTTON: Adjusts the microphone power in the transmit mode.
This is a push on-push off switch. When the MIC symbol is visible in the
LCD screen it indicates a reduced microphone power level. This mode is
useful when operating in a high noise enviroment.
4. LOC BUTTON. To be used to reduce the gain of the RF amplifier under
strong signal conditions. This is a push-push switch. When the “LOC”
indicator is visible in the LCD screen the receiver is in the local mode (short
range). Normally the unit would be operated in the distant mode (long range)
with the “LOC” disabled.
5. CH 19 BUTTON. Press this button for instant selection of highway
channel 19. The channel or frequency display flashes channel 19 when
instant channel 19 is selected. The rotary channel selector is bypassed when
the CH19 button is activated. Press the CH 19 button again to return to
normal channel selection.
