(420-5080)                 Care and Maintenance       Faxback Doc. # 49638

Your Optimus CD-3790 Portable Compact Disc Player is an example of
superior design and craftsmanship.  The following suggestions will help
you care for your CD player so you can enjoy it for years.

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

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

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

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

  Use only fresh batteries of the required size and recommended type.
  Batteries can leak chemicals that damage your CD player's electronic
  parts.

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

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

REPLACING THE DC ADAPTER'S FUSE

If the CD player stops operating, check the fuse in the DC adapter's
cigarette-lighter plug.  If it has blown, follow these steps to replace it
with a 3-amp, 5 x 20 mm, fast-acting fuse such as Cat. No. 270-1054 (not
supplied).

CAUTION:  Using a fuse that does not meet these ratings can damage your CD
          player or the vehicle's electrical system.

1.  Carefully unscrew the tip of the cigarette-lighter plug.

2.  Remove the old fuse and replace it with the new fuse.

3.  Screw the cigarette-lighter plug's tip back onto the body.

CD CARE TIPS

Even though a CD is very durable, you should handle it with care.

  Keep the CD inside the CD player or in its protective case or sleeve
  when you are not playing it.

  Handle a CD by its edges to avoid fingerprints that can prevent the CD
  player's laser beam from accurately reading the CD.  Your local
  RadioShack store sells a suitable CD cleaner kit.

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

  Keep the CD dry.  A water drop can act as a lens and affect the laser
  beam's focus.

  Never use chemicals such as record cleaning sprays, anti-static sprays
  or fluids, benzene or thinner to clean CD's.  These chemicals will
  permanently damage the plastic surface of the CD.

  If a CD skips when you try to play it, the CD might be scratched.  Your
  local RadioShack store sells a Scratch 'n Fix kit (Cat. No. 42-127) that
  might stop the skip.  Also see "Troubleshooting" in Faxback Doc.
