CONTROLS AND FUNCTIONS
CD (D
1. SQUELCH — The squelch control is used to eliminate background noise during
the absence of a transmission. Turn the control fully counterclockwise, then
slowly rotate it back clockwise until all noise disappears. At this setting any
transmission must be slightly stronger than the background noise to “Break
Squelch" or to be heard. Further clockwise rotation will increase the threshold at
which a signal will be heard. You can select any level to “Break Squelch",
2. S/RF METER — This LED meter shows the relative strength of the received signal
or transmit power.
3. CHANNEL INDICATOR — Displays the channel currently in use.
4. CHANNEL SELECTOR — This switch selects the desired channel for transmission
and reception. All channels, except channel 9, may be used for communications
between stations operating under different license. Channel 9 has been reserved by
the D.O.C. for emergency communications involving the immediate safety of
individuals or the immediate protection of property. Channel 9 also may be used
to render assistance to a motorist. This is the D.O.C. rule and applies to all opera­
tors of CB radios,
5. TX INDICATOR — An LED lights to indicate when the radio is transmitting.
6. MICROPHONE — The operational mode of the CB is controlled by the push-to­
talk switch on the microphone. Press the switch to activate the transmitter and
disable the receiver. Release the switch to enable the receiver and disable the
transmitter. When transmitting, hold the microphone about 2 inches from your
mouth and speak clearly in a normal voice. The microphone included with the
