(120-2108)                 Care and Maintenance       Faxback Doc. # 32411

Your Optimus In-Dash High-Power AM/FM Stereo Cassette with Auto Reverse is
an example of superior design and craftsmanship.  The following suggestions
will help you care for the stereo so you can enjoy it for years.

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

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

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

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

Modifying or tampering with the stereo's internal components can cause a
malfunction and might invalidate your stereo's warranty and void your FCC
authorization to operate it. If your stereo is not performing as it should,
take it to your local Radio Shack store for assistance.

THE FCC WANTS YOU TO KNOW

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

     Moving your stereo away from the receiver.

     Contacting your local Radio Shack store for help.

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

CLEANING THE TAPE-HANDLING PARTS

Clean the tape head after about every 20 hours of playing time.  Insert a
special head-cleaning cassette (such as Cat. No. 44-1202), and follow the
cleaning cassette's direction to clean the tape head.

RESTORING TAPE TENSION AND SOUND QUALITY

After you play a cassette tape a few times, the tape might become tightly
wound on the reels.  This can cause playback sound quality to deteriorate.

To restore the sound quality, fast-forward the tape from the beginning to
the end of one side, then completely rewind it.  Then loosen the tape reels
by gently tapping each side of the cassette's outer shell on a flat
surface.

CAUTION:  Be careful not to damage the cassette when tapping it.  Do not
          touch the exposed tape or allow any sharp objects near the
          cassette.

REPLACING FUSES

If the stereo does not operate, you might need to replace the red power
wire's fuse with the supplied spare fuse.  If the clock resets or stored
stations are lost when the ignition is off, you might need to replace the
yellow power/memory wire's fuse with the supplied spare fuse.  Check both
fuses.

1.  Disconnect the cable from the vehicle battery's negative (-) terminal.

2.  Push together and twist the fuse holder's parts until they spring open.

3.  If either fuse is blown, replace it.  Use only standard 1 1/4 inch fast
    acting fuses with the proper rating.  The red power wire's fuse must be
    6.0 amps, and the yellow power/memory wire's fuse must be 0.5 amps.

    CAUTION:  The supplied spare fuses have the proper ratings.  Make sure
              you replace a fuse only with another fuse of the same rating.

4.  Reassemble both fuse holders by pushing together and twisting the two
    parts back together.

5.  Reconnect the cable to the vehicle battery's negative (-) terminal.

RESETTING THE STEREO

If information on the stereo's display disappears and your stereo does not
work at all, you might have to reset it.

To reset your stereo, simply turn your vehicle's ignition off, wait about 3
minutes, then turn your vehicle's ignition on again.
