Caller ID System 320  (430-0957) Care and Maintenance  Faxback Doc. # 7021

Your Radio Shack Caller ID System 320 is an example of superior design
and craftsmanship.  The following suggestions will help you care for the
system so you can enjoy it for years.

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

-Handle the system gently and carefully.  Dropping it can damage its
 circuit boards and case and can cause it to work improperly.

-Use and store the system only in normal temperature environments.
 Temperature extremes can shorten the life of electronic devices, and
 distort or melt plastic parts.

-Keep the system away from dust and dirt, which can cause premature wear
 of parts.

-Use only fresh batteries of the recommended size and type.  Always remove
 an old or weak batteries.  They can leak chemicals which can destroy
 electronic circuits.

-Occasionally wipe the system with a damp cloth to keep it looking new.
 Do not use harsh chemicals, cleaning solvents or strong detergents to
 clean the system.

-Modifying or tampering with your system's internal components can cause
 a malfunction and might invalidate the system's warranty.  IF your system
 is not operating as it should, take it to your local radio Shack store
 for assistance.  If the trouble is harming the telephone lines, the
 telephone company might ask you to disconnect your system until you have
 resolved the problem.

LIGHTENING

You system has built-in protection circuits to reduce the risk of damage
from surges in telephone line current.  These protection circuits meet or
exceed the FCC requirements.  However, lightening striking the telephone
lines can damage your system.

Lightening damage is not common.  However, if you live in an area that has
severe electrical storms, we suggest you unplug your system during storms
to reduce the possibility of damage.
