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 several minutes before
trying again.
• Do not press and hold 
PUSH TO
TALK
 when you are not talking. (This
is called 
dead keying
.)
• Assist callers with directions, infor-
mation about road conditions, and
any other reasonable requests.
MAXIMUM RANGE
The maximum range and quality of CB
transmissions vary depending on these
conditions:
• Amount of power in the batteries
• The surrounding terrain — moun-
tains and tall buildings limit the range
• Weather conditions
• The number of nearby CBs operating
on the same channel
To ensure maximum range, always keep
fresh alkaline batteries or fully charged
nickel-cadmium batteries in your TRC-
237 when using battery power.
