Before you use your CB, you should know
how to use it effectively and courteously.
“Transmission Courtesy” on Page 10
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 counterclockwise.
3. Turn
RF GAIN
fully clockwise.
4. Turn on the transceiver by turning
VOLUME
clockwise until it clicks. All LCD
segments appear briefly. Then the
channel and
HN
appear.
5. Rotate the channel selector, or
repeatedly press (or hold down)
UP

DOWN
on the microphone until the
desired channel appears.

hear noise between transmissions,
