OPERATION
SETTING SQUELCH
Caution: Do not attempt to use your
CB without first connecting it to an an-
tenna.
1. Turn VOLUME clockwise until it
clicks to turn on the CB, then set it
to about halfway between the min-
imum and maximum settings. The
CB tunes to the last-selected
channel.
2. Turn SQUELCH fully counterclock-
wise. You hear background noise
and the green BUSY LED lights.
3. Adjust VOLUME to a comfortable
setting.
4. Turn SQUELCH clockwise just until
the background noise stops.
Note: To receive weaker transmis-
sions, turn
SQUELCH counter-
clockwise.
USING AUTOMATIC
NOISE LIMITING
If you hear low-level popping noises
while receiving transmissions, slide
ANL/OFF to ANL to turn on the auto-
matic noise limiting circuit. Otherwise,
leave
ANL/OFF set to OFF (see “Re-
ducing Noise” on Page 16).
