CARE AND MAINTENANCE

Your RadioShack CT-400 Handheld Cellular Phone is an example of superior design and craftsmanship and should be treated with care. These suggestions allow you to enjoy this phone for many years.

Keep the phone and all its parts and accessories out of the reach of children.

Keep the phone dry. Precipitation, humidity and liq- uids might contain minerals that corrode electronic circuits.

Do not use or store the phone in dusty, dirty areas. Its moving parts can be damaged.

Do not store the phone in hot areas. Temperature extremes can shorten the life of electronic devices, damage batteries, and warp or melt plastic parts.

Do not store the phone in cold areas. When the phone warms up (to its normal operating tempera- ture), moisture can form inside the phone, which could damage the phone’s electronic circuits.

Do not attempt to open the phone. Non-expert han- dling of the phone can damage it.

Do not drop, knock, or shake the phone. Rough han- dling can break internal circuit boards.

Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the phone. Wipe it with a soft cloth slightly dampened in a mild soap and wa- ter solution.

Modifying or tampering with your phone’s internal compo- nents could violate its warranty and void your FCC autho- rization to use it. If the phone or any of its accessories are not working properly, take them to your local RadioShack store for assistance.
