CARE AND MAINTENANCE
Your RadioShack Caller ID System 999 Telephone Big Button Caller ID 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 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 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 circuit
boards and cases and can cause the phone to work improperly.
Use only fresh batteries of the required size and type. Old batteries can
leak chemicals that damage your phone’s electronic 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 and void your FCC authorization to oper-
ate 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 solve the problem.
