This table lists the code meanings in the form of a 
statement. They can also be phrased as questions. For 
example, “10-6: Are you busy?”, “10-20: What is your 
location?”.

TIPS FOR USING YOUR CB 

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

• Truck drivers and delivery personnel can learn road 

and traffic conditions and get assistance in locating 
destinations. A CB is also good company on long road 
trips.

• On construction crews, a CB quickly pays for itself 

when you are calling for additional materials or 
coordinating the activities of different work crews.

• For security officers, a CB is more than a convenience 

— it is a must for both safety and efficiency.

• Keep in touch with home while 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.

• If you are a two-car (or more) family, CBs 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 call for assistance!

• Camping, fishing, and other sports are more fun with a 

CB. Locate a buddy or find out “what’s cooking” back at 
camp.

• 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.
