Caller ID System 1000 Telephone (430-0965) Care and Maintenance Faxback Doc. # 17222 Your Radio Shack Caller ID System 1000 Telephone with 3-Memory Speed- Dialing is an example of superior design and craftsmanship. The following suggestions will help you care for your phone so you can enjoy it for years. Keep the phone dry. If the phone gets wet, wipe it dry immediately. Liquids might contain minerals that can corrode the electronic circuits. Use and store the phone only in normal temperature environments. Temperature extremes can shorten the life of electronic devices, damage batteries, and distort or melt plastic parts. Handle the phone gently and carefully. Dropping it can damage the circuit boards and case, and can cause the phone to work improperly. Keep the phone away from dust and dirt, which can cause premature wear of parts. Wipe the phone with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the phone. Modifying or tampering with the phone's internal components can cause a malfunction and might invalidate your phone's warranty. If your phone is not performing as it should, take it to your local Radio Shack store for assistance.
