Your Optimus CD-3328 Portable Triple Compact Disc Player with AM/FM Stereo
Cassette Recorder 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-3328 dry.  If it gets wet, wipe it dry immediately. Liquids
  might contain minerals that can corrode the electronic circuits.
  
  Use and store the CD-3328 only in normal temperature environments.
  Temperature extremes can shorten the life of electronic devices, damage
  batteries, and distort or melt plastic parts.

  Handle the CD-3328 gently and carefully.  Dropping it can damage the
  circuit boards and can cause the system to work improperly.

  Keep the CD-3328 away from dust and dirt, which can cause premature wear
  of parts.

  Wipe the CD-3328 with a damp cloth occasionally to keep it looking new.
  Do not use harsh chemicals, cleaning solvents, or strong detergents to
  clean the system.

Modifying or tampering with the CD-3328's internal components can cause a
malfunction and might invalidate its warranty and void your FCC
authorization to operate it.  If the CD-3328 is not performing as it
should, take it to your local RadioShack store for assistance.

CD Care Tips

Even though a compact disc is 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
   beam's 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 (RadioShack Cat. No. 42-127) to repair the disc.

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 or TAPE 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 place 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 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 about every 20 hours of tape player operation.

1.  Disconnect all power sources.

2.  Open the cassette compartment door.

3.  With the eraser end of a pencil, gently press down on the erase
    protection tab sensor.

4.  While holding down the erase protection tab sensor, press RECORD to
    expose all the tape-handling parts.

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

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

Your local RadioShack 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.  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.
