CARE AND MAINTENANCE
Your RadioShack ET-550 25-Channel Dual Keypad Cordless Telephone is an ex-
ample of superior design and craftsmanship. The following suggestions will help you
care for your cordless telephone 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.
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.
Handle the phone gently and carefully. Dropping it can damage cir-
cuit boards and cases and can cause the phone to work improperly.
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 telephone’s internal components can cause a mal-
function and might invalidate your telephone’s warranty and void your FCC authori-
zation to operate it. If your phone is not performing as it should, take it to your local
RadioShack 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
problem.
