TRC-485 40-Channel AM/SSB CB Transceiver (210-1577) Operation Hints Faxback Doc. # 33140 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 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, 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. 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 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. MAXIMUM RANGE The maximum range and quality of CB radio transmissions vary depending on the following 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 range The surrounding terrain - mountains and tall buildings limit the range Weather conditions The number of nearby radios operating on the same channel Standing wave ratio (SWR) between the antenna and the CB. You can check the SWR between the CB and a mobile or base station antenna using an SWR tester (such as Cat. No. 21-523). Follow the instructions supplied with the SWR tester and the mobile or base station antenna to change the SWR, if necessary. NOTE: Your CB radio's transmission range is generally line-of-sight. 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 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. USING COMMON 10-CODES Citizen's band operators and CB radio users have largely adopted the 10-codes for standard questions and answers.
