Caller ID System 40  (430-0961)  Care and Maintenance  Faxback Doc. # 7369

Your Radio Shack Caller ID System 40 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.

              Use only fresh batteries of the required size and type.
              Always remove 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 the system's internal components can cause a
malfunction and might invalidate the system's warranty and void your FCC
authorization to use it.  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 the system until you have resolved the problem.

THE FCC WANTS YOU TO KNOW

In the unlikely event that your system causes problems on the telephone
line, the telephone company can disconnect your service.  Normally, the
telephone company attempts to notify you in advance.  However, if advance
notice is not practical, the telephone company notifies you as soon as
possible and advises you of your right to file a complaint with the FCC.

The telephone company can also make changes to its lines, equipment,
operations, or procedures that could affect the operation of this system.
Normally, the telephone company notifies you of these changes in advance
to allow you to take the necessary steps to prevent interruption of your
telephone service.

If the system is not performing as it should, check the connection to the
telephone line.  Calls are automatically switched and routed through
complex equipment, so you might occasionally hear noise on the line.  When
a call is too noisy, hang up and redial the number.  If you still have
problems, immediately disconnect the system.  If a telephone on the same
line works properly, the fault is in the system or its installation.  If
you are unable to locate the problem, take the system to your local
Radio Shack store for assistance.

LIGHTNING

Your 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, lightning striking the telephone
lines can damage your system.

Lightning 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.
