Controls and Indicators
Refer to controls, indicators and connectors as illustrated below:

A. Front Panel
1.
Off/On/Volume . Turn clockwise to turn power on and set the
desired listening volume.
2.
Squelch . This control is used to cut off or eliminate receiver
background noise in the 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. Adjust until the receiver
noise disappears. This will require the incoming signal to be
slightly stronger than the average receiver 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.
Microphone Connector . This front mounted, screw-on connector
allows for convenient removal of the microphone plug when
storage is required. The microphone MUST be connected to the
unit at all times when in use, for proper operation. The screw-on
connection enhances the life of the microphone cord as well.
4.
Channel 9/Normal Switch . Used for instant selection of
emergency channel 9 (CH 9 position). In NOR position, all 40 CB
channels are selected by the UP/DOWN CHANNEL BUTTONS.

selected channel. The PA function should not be used unless a PA
speaker is connected.

S-RF/Power Meter . Shows relative transmitter RF output power
and input signal strength when receiving. The five LED (Light
Emitting Diode) segments glow to indicate receive or transmit
activity.
7.

transmit mode.

9.
Channel Selector Switch . When turned, this knob is used to
select any one of the forty citizens band channels desired.
For a “RAPID” change of channels, depress and hold the desired
button (up and down). This allows all 40 channels to be covered
in about 6 seconds.
