CARE AND MAINTENANCE

Your RadioShack TRC-442 Full-Power 40-Channel Mobile CB Radio is an example of superior design and craftsmanship. The following suggestions will help you care for your CB so you can enjoy it for years.

Keep the CB dry. If it gets wet, wipe it dry immediately. Liquids might contain minerals that can corrode the electronic circuits.

Keep the CB away from dust and dirt, which can cause premature wear of parts.

Handle the CB gently and carefully. Dropping it can damage circuit boards and cases and can cause the CB to work improperly.

Wipe the CB with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the CB.

Modifying or tampering with the CB’s internal components can cause a malfunction and might invalidate the CB’s warranty and void your FCC authorization to operate it. If your CB is not performing as it should, take it to your local RadioShack store for assistance.
