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
