Operation

USING THE PA AMPLIFIER

Your CB has a built-in PA (public address) 
amplifier. With an optional PA speaker (see 
“Connecting a PA Speaker” on Page 5), you 
can turn your radio into a mobile public 
address system.

1. Turn on the transceiver. Set 

PA

/

MON

/

CB

 

to 

PA

F7

 appears.

2. To transmit, hold down 

PUSH

 

TO

 

TALK

 

on the microphone. Hold the 
microphone 2–3 inches from your mouth 
and speak in a normal tone of voice.

3. Turn 

VOLUME

 for the desired volume 

level. If you hear high-pitched squeal, 
turn 

VOLUME

 counterclockwise until the 

squeal stops.

Note: To avoid acoustic feedback, the 
speaker should be at least 6 feet from 
the CB. If you experience feedback, 
avoid keying the microphone until you 
have moved the speaker away from the 
CB.

To turn off the PA amplifier, turn the 
transceiver off. Or, set 

PA

/

MON

/

CB

 to 

CB

 for 

CB communication.

USING MONITOR

You can use your CB as a receiver to listen 
to transmissions on an optional PA speaker. 
With a PA speaker connected, set 

PA

/

MON

/

CB

 to 

MON

. Your CB cannot transmit and you 

hear sound only from the external PA 
speaker.

USING THE COMPASS

You can easily view your current heading at 
a glance. There are eight cardinal points on 
the display — north, northeast, east, 
southeast, south, southwest, west, 
northwest. Calibration helps the compass 
better separate the earth’s magnetic field 

from the magnetic field generated by 
external influences (such as your vehicle), 
providing more accurate heading 
information.

Calibrate the compass anytime you move it, 
or whenever distortion continuously appears. 
Before calibration, peel off the backing on 
one side of the tape and attach the tape to 
the back of the compass, then mount the 
compass by peeling off the backing on the 
other side of the tape, then press the 
compass onto the level mounting surface.

Notes:

• Before calibration, end CB transmission 

and make sure the CB is not tuned to 
the Emergency channel 9 or 19 or in PA 
mode.

• Do not calibrate the compass near metal 

or a strong magnetic field.

• The compass is not available in TX 

mode.

1. Hold down 

CAL

 for a second. All eight 

cardinal points flash.

2. Drive your vehicle in two complete 

circles. Be sure your vehicle is on level 
ground, in an open area, such as a 
parking lot.

3. Press 

CAL

 to confirm calibration

After calibration, the current compass 
heading displays. For example, if the 
compass heading is south, the south cardinal 
point appears. Or, if the compass heading is 
northeast-north, the northeast cardinal point 
appears and the north cardinal point flashes.

USING MEMORY

You can store three channels in the memory. 
The preset channel stored in 

MEM1

MEM2

and 

MEM3

 is Channel 1. Press the memory
