STA-825 DIGITAL SYNTHESIZED AM/FM STEREO RECEIVER
(310-2105)                 Care and Maintenance       Faxback Doc. # 32772

Your Optimus STA-825 AM/FM Stereo Receiver is an example of superior design
and craftsmanship.

The following suggestions will help you care for your receiver so you can
enjoy it for years.

    Keep the receiver dry.  If it does get wet, wipe it dry immediately.
    Liquids can contain minerals that can corrode the electronic circuits.

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

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

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

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

Modifying or tampering with the receiver's internal components can cause a
malfunction and might invalidate its warranty and void your FCC author-
ization to operate the receiver.  If your receiver is not performing as it
should, take it to your local Radio Shack store.  Our Personnel can assist
you and arrange for service if needed.

THE FCC WANTS YOU TO KNOW

Your receiver might cause interference on other radio/TV devices even when
it is operating properly.  To determine whether your receiver is causing
the interference, turn off your receiver.  If the interference goes away,
your receiver is causing the interference.  Try to eliminate the
interference by:

    Moving your receiver away from the other device.

    Connecting your receiver to an outlet that is on a different electrical
    circuit from the other device.

    Contacting your local Radio Shack store for help.

If you cannot eliminate the interference, the FCC requires that you stop
using your receiver.

CAUTION:  Any changes or modifications in construction of this device which
          are not expressly approved by the party responsible for
          compliance could void the user's authority to operate the
          equipment.

REPLACING THE FUSE

The receiver's fuse protects it from short circuits and AC power surges. If
the receiver stops working and the PROTECTION indicator is not on, replace
the fuse.  Use a fuse rated at 2.5 amps and at least 125 volts.

CAUTION:  To protect the receiver, use only the recommended type of fuse.

If the receiver stops working and the PROTECTION indicator comes on, or if
you replace the fuse and the receiver still does not work, see "Built-in
Protection Circuits", on Faxback Doc. # 19451.

Follow these steps to replace the fuse.

WARNING:  To avoid a shock hazard, turn off the POWER and unplug the
          receiver's power cord before you replace the fuse.

1.  Use a screwdriver to unscrew the fuse compartment cap on the back of
    the receiver.

2.  Remove the old fuse and place the new fuse in the fuse compartment cap.
    Then, replace the cap and use a screwdriver to screw it back into the
    fuse compartment.
