get more enjoyment from your CB.
RECEIVING
TRANSMISSIONS AND
ADJUSTING SQUELCH
1. Turn
SQUELCH
fully counterclock-
wise.
2. Turn on the transceiver by turning
VOLUME
clockwise until it clicks. The
channel display lights and the chan-
nel appears, and the RX indicator
lights.
3. Set
OUT CH9 CH19
to
OUT
to select
a channel other than an emergency
channel.
4. Rotate the channel selector until the
display shows the desired channel.
5. Adjust
VOLUME
to a comfortable lis-
tening level.
6. To cut out background noise be-
tween transmissions, wait until there
is no signal, then slowly turn
SQUELCH
clockwise until the back-
ground noise stops.
Note:
To receive very weak signals,
turn
SQUELCH
counterclockwise.
You hear noise between transmis-
sions, but you also hear weak trans-
missions (those not strong enough
to break through a higher squelch
setting).
7. To turn off the CB, turn
VOLUME
counterclockwise until you hear it
click. The display and indicators turn
off.
