Band" antenna designed for
CB only.
Tu rning on
Tu rn volume co nt rol cloc kwise to turn power on
and set the desired listening vo l u m e.
CB Ante n n a
Only a pro pe rly matched antenna sys tem will
a l l ow maximum power output.
In mobile installations (ca r s,t ru c k s,bo at s,e tc. ) ,
an antenna sys tem that is non-dire ctional should
be used.
When installed in a bo at,the tra n s ce i ver will not
o pe rate at maximum efficiency without a gro u n d
p l ate unless the vessel has a steel hull.Be fo re
installing the tra n s ce i ver in a bo at,consult yo u r

Sq u e l c h
This co nt rol is used to cut off or eliminate re ce i ve r
b a c kg round noise in the absence of an inco m i n g
s i g n a l . Adjust until the re ce i ver noise disappe a r s.
This will re q u i re the incoming signal to be slight l y
s t ronger than ave rage re ce i ver noise.Fu rther cloc kwise ro t ation will increase the threshold leve l
which a signal must ove rcome in order to be heard.
Only strong signals will be heard at a maximum
c l oc kwise setting.

Squelch is the “control gate”for incoming signals.
1 . Fullclockwise rotation closes the gate
allowing only very strong signals to enter.
2 . Fullcounterclockwise rotation opens the “gate”
allowing all signals in.
