CB COURTESY
• Wait for a pause in someone
else’s transmission before you
ask for a break.
• If you do not receive an answer
to your call after a second
attempt, sign off and wait sev-
eral minutes before trying again.
• Do not hold down the PUSH TO
TALK button when you are not
talking. (This is called dead key-
ing.)
• Assist callers with directions,
road conditions, and any other
reasonable requests.
MAXIMUM RANGE
The maximum range and quality of
CB transmissions vary depending on
these conditions:
• The type and quality of antenna
used
• The height of the antenna’s
mounting location — the higher
the antenna, the better the sig-
nal’s range
• The surrounding terrain —
mountains and tall buildings limit
the range
• Weather conditions
• The current setting of RANGE on
your CB
• The number of nearby CBs
operating on the same channel
• Standing Wave Ratio (SWR)
between the antenna and the
CB. You can check the SWR
between the CB and a mobile
antenna using an SWR tester
(Cat. No. 21-523). Follow the
instructions supplied with the
SWR tester and the mobile
antenna to change the SWR, if
necessary.
