CARE AND MAINTENANCE

Your RadioShack ET-551 25-Channel Cordless Phone with 10-Number Memory is an example of superior design and craftsmanship. The following suggestions will help you care for your cordless phone so you can enjoy it for years.

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

Handle the phone gently and carefully. Dropping it can damage cir- cuit boards and cases and can cause the phone to work improperly.

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.

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 deter- gents to clean the phone.

Modifying or tampering with the phone’s internal components can cause a malfunc- tion and might invalidate your phone’s warranty and void your FCC authorization to operate it. If your phone is not performing as it should, take it to your local Ra- dioShack store for assistance. If the trouble is affecting the phone lines, the phone company might ask you to disconnect your phone until you have resolved the prob- lem.
