OPERATIONAL HINTS
Like most activities, CB radio has its customs and courtesies.
The follo wing t ips wi ll help y ou get t he mos t enjoyment fr om you r
walkie-talkie.
COMMON USES FOR A CB RADIO
Business Uses
• Truck drivers and delivery personnel can learn road and
traffic conditions and get assistance in locating destinations. 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 different work crews.
• For security officers, a CB radio is more than a convenience — it is a must for both safety and efficiency.
Personal Uses
• Keep in touch with home whi le driving 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.
27
21-1672.fm Page 28 Thursday, August 5, 1999 12:04 PM
• If you are a two-car (or more) family, CB radios are great
for communicating 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 assurance 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.
TRANSMISSION 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 hold down the
(This is called dead keying.)
• Assist callers with directions, information about road conditions, and any other reasonable requests.

21-1672.fm Page 29 Thursday, August 5, 1999 12:04 PM
MAXIMUM RANGE
The maximum range and quality of CB radio t ransmissions vary
depending on the fol lowing conditions:
• The type and quality of antenna used
• The height of the antenna’ s mounting location — the higher
the antenna, the better the signal’s r ange
• The surrounding terrain — mountains and tall buildings
limit range
• Weather co nditions
• The number of nearby radios operating on the same chan-
nel
Note:
Your CB radio’s transmission range is generally line-ofsight. To ensure maximum range, always keep fresh or fullycharged batter ies in your CB radio.
