System 420 Caller ID
(430-0971)                 Care and Maintenance       Faxback Doc. # 39665


Your Radio Shack System 420 Call Waiting Caller ID is an example of
superior design and craftsmanship.  The following suggestions will help
you care for your 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 the electronic circuits.

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

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

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

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

Modifying or tampering with the system's internal components can cause a
malfunction and might invalidate its warranty and void your FCC
authorization to operate it.  If your system is not performing as it
should, take it to your local Radio Shack store for assistance.  If the
trouble is affecting the phone lines, the phone company might ask you to
disconnect your system until you have resolved the problem.

THE FCC WANTS YOU TO KNOW

In the unlikely event that your system causes problems on the phone line,
the phone company can temporarily disconnect your service.  If this
happens, the phone company attempts to notify you as soon as possible and
advises you of your right to file a complaint with the FCC.

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

LIGHTNING

Your system has built-in protection circuits to reduce the risk of damage
from surges in phone line or power line current.  These protection
circuits meet or exceed FCC requirements.  However, lightning striking the
phone line can damage your system.

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