Caller ID System 400  (430-0958) Care and Maintenance  Faxback Doc. # 15766

The Radio Shack Caller ID System 400 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 old 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.  If the 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.

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
so you can take the necessary steps to prevent interruption of your
telephone service.

This system complies with the limits for a Class B device as specified in
Part 15 of FCC Rules.  These limits provide reasonable protection against
radio and TV interference in a residential area.

However, your system might cause TV or radio interference even when it is
operating properly.  To eliminate interference, you can try one or more of
the following corrective measures.

    Reorient or relocate the receiving antenna

    Increase the distance between the system and the radio or TV.

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 your
system to your local Radio Shack store for assistance.

LIGHTNING

The 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 the 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.
