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 min- utes before trying again.

Do not hold down the talk button when you are not talking. (This is called dead keying.)

Assist callers with directions, information about road conditions, and any other reasonable requests.

MAXIMUM RANGE

The maximum range and quality of CB transceiver transmissions vary depending on the following condi- tions:

The type and quality of antenna used

The height of the antenna’s mounting location — the higher the antenna, the better the signal’s range

The surrounding terrain — mountains and tall buildings limit the range

Weather conditions

The number of nearby CBs operating on the same channel

Note: Your transceiver’s transmission range is gen- erally line-of-sight. To ensure maximum range, al- ways keep fresh or fully-charged batteries in your CB.

USING COMMON 10-CODES

Citizen’s band operators and CB users have largely adopted the 10-codes for standard questions and an- swers. These codes permit faster communication and better intelligibility in noisy areas.
