OPERATIONAL HINTS

Like most activities, CB radio has its
customs and courtesies. The following
tips will help you get the most enjoyment
from your CB.

COMMON USES FOR A CB

Personal Uses

• Keep in touch with home while driv-

ing to work, to the store, or to a
social activity. Let your family know
you are tied up in traffic or that you
will stop by the store on the way
home.

• If you are a two-car (or more) family,

CB radios are great for communicat-
ing with family members while they
are in their cars.

• Contact friends or neighbors — find

out “what’s happening” or plan a
get-together.

• Ever have car trouble or run out of

gas on the highway? What an assur-
ance it is to be able to radio for
assistance!

• Camping, fishing, and other sports

are more fun with a CB radio. Locate
a buddy or find out “what’s cooking”
back at camp.

Business Uses

• For security officers, a CB is more

than a convenience — it is a must
for both safety and efficiency.

• Truck drivers and delivery personnel

can learn road and traffic conditions
and get assistance in locating desti-
nations. A CB radio is also good
company on those “long hauls.”

• On construction crews, a CB radio

quickly pays for itself when you are
calling for additional materials or
coordinating the activities of differ-
ent work crews.

TRANSMISSION 
COURTESY

Please follow these guidelines of radio
courtesy when using your CB.

• 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 hold down 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.
