CARE AND MAINTENANCE

Your Optimus CD-3320 Portable AM/FM Stereo Cassette Recorder with CD
Player 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 CD-3320 dry.  If it gets wet, wipe it dry immediately.
    Liquids might contain minerals that can corrode the electronic circuits

    Use and store the CD-3320 only in normal temperature environments.
    Temperature extremes can shorten the life of electronic devices and
    distort or melt plastic parts.

    Keep the CD-3320 away from dust and dirt, which can cause premature
    wear of parts.

    Handle the CD-3320 gently and carefully. Dropping it can damage circuit
    boards and cases and can cause the CD-3320 to work improperly.

    Use only fresh batteries of the required size and type.  Old batteries
    can leak chemicals that damage your CD-3320's electronic parts.

    Wipe the CD-3320 with a damp cloth occasionally to keep it looking new.
    Do not use harsh chemicals, cleaning solvents, or strong detergents to
    clean the CD-3320.

Modifying or tampering with the CD-3320's internal components can cause a
malfunction and might invalidate its warranty and void your FCC
authorization to operate it.  If the CD-3320 is not performing as it
should, take it to your local Radio Shack store for assistance.

CD CARE TIPS

Even though a compact disc is very durable, treat the CD surface with care.

    Do not write on either side of the CD, particularly the non-label side
    (signals are read from the non-label side).

    Do not store CDs in high temperature, high-humidity locations.  They
    might warp.

    Keep CDs dry.  A water drop can act as a lens and affect the laser
    beams focus.

    Always handle a CD by the edges to avoid fingerprints and always keep
    it in its protective case or sleeve when it is not in use. Fingerprints
    and scratches on the CD's surface can prevent the laser beam from
    correctly reading the digital information.  If the CD gets scratched,
    use Scratch 'n Fix (Radio Shack Cat. No. 42-127) to repair it.

TAPE TIPS

ERASING A CASSETTE TAPE

To erase a previously recorded tape, simply record over it.  To erase the
entire cassette tape, set FUNCTION to CD and do not load a CD, then start
recording and let the tape record to the end.

To quickly erase both sides of a cassette tape, use a bulk tape eraser
(such as Cat. No. 44-232, not supplied).

PREVENTING ACCIDENTAL ERASURE

Cassette tapes have two erase-protection tabs, one for each side.  To
protect a recording from being accidentally recorded over or erased, use a
screwdriver to remove one or both erase-protection tabs.

To record on a tape side after you remove the erase-protection tab, place
a piece of strong plastic tape over that side's erase-protection hole.  Be
sure you cover only the hole originally covered by the tab.

NOTE:  Removing the erase-protection tabs does not prevent a bulk eraser
       from erasing a cassette tape.

CLEANING THE TAPE-HANDLING PARTS

Dirt, dust or particles of the tape's coating can accumulate on the tape
heads and other parts that the tape touches.  This can greatly reduce the
performance of the cassette player.  Use the following cleaning procedure
after every 20 hours of tape player operation.

1.  Disconnect all power sources.

2.  Press STOP/EJECT to open the cassette compartment door.

3.  Press RECORD while pushing in the lever at the top left hand side.

4.  Use a cotton swab dipped in denatured alcohol or tape head cleaning
    solution to clean the record/play head, pinch roller, capstan, tape
    guides, and erase head.

5.  When you finish cleaning, press STOP/EJECT and close the cassette
    compartment door.  Then reconnect power.

Your local Radio Shack store sells a complete line of cassette deck
cleaning products.

RESTORING TAPE TENSION AND SOUND QUALITY

After you play a cassette tape several 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.
