OPERATION
Before you use your CB, you should
know how to use it effectively and cour-
teously. “Operational Hints” on Page 14
contains information that will help you
get more enjoyment from your CB.
RECEIVING
TRANSMISSIONS AND
ADJUSTING SQUELCH
1. Set
PA/MON/CB
to
CB
.
2. Turn
SQUELCH
fully counterclock-
wise.
3. Turn
RF GAIN
fully clockwise.
4. Turn on the transceiver by turning
VOLUME
clockwise until it clicks.
The channel display lights, the
channel appears, and the RX indica-
tor lights.
5. Set
OUT/CH9/CH19
to
OUT
to select
a channel other than an emergency
channel.
6. Rotate the channel selector, or
repeatedly press (or hold down)
UP
or
DOWN
on the microphone until
the display shows the desired chan-
nel.
7. Adjust
VOLUME
to a comfortable lis-
tening level.
8. To cut out background noise
between transmissions, wait until
there is no signal, then slowly turn
SQUELCH

ground noise stops.
Notes:
To receive very weak signals, turn
SQUELCH
counterclockwise. You
hear noise between transmis-
sions, but you also hear weak
transmissions (those not strong
enough to break through a higher
squelch setting).
If you experience interference
from nearby frequencies, turn
RF
GAIN
counterclockwise to reduce
the receiver’s sensitivity.
