Correct Handling

Do not drop the disc while handling. Hold the disc so you will
not leave fingerprints on the surface. Do not affix tape, paper, or
gummed labels to the disc. Do not write on the disc.

Disc Cleaning

Fingerprints, dust, or soil on the surface of the disc could cause
the CD player to skip. For routine cleaning, wipe the playing
surface with a clean, soft cloth from the center of the disc to the
outer edge. If the surface is heavily soiled, dampen a clean, soft
cloth in a solution of mild neutral detergent before cleaning the
disc.

Disc Accessories

There are various accessories available on the market for
protecting the disc surface and improving sound quality.
However, most of them will influence the thickness and/or
diameter of the disc. Using such accessories can cause the disc to
be out of standard specifications and may create operational
problems. We recommend not using these accessories on discs
played in Alpine CD players.

PRECAUTIONS

Never Attempt the Following

Do not grip or pull out the disc while it is being pulled back into
the player by the automatic reloading mechanism.
Do not attempt to insert a disc into the unit when the unit power
is off.

Inserting Discs

Your player accepts only one disc at a time for playback. Do not
attempt to load more than one disc.
Make sure the label side is facing up when you insert the disc.
Your player will automatically eject any disc that is inserted
incorrectly. If the player continues to eject a correctly inserted
disc, push the RESET switch with a pointed object such as a
ballpoint pen.
Playing a disc while driving on a very bumpy road may result in
skips, but this will not scratch the disc or damage the player.

New Discs

As a protective measure to prevent the CD from jamming, the CD
player will automatically eject discs with irregular surfaces or
inserted incorrectly. When a new disc is inserted into the player
and ejected after initial loading, using your finger, feel around the
inside of the center hole and outside edge of the disc. If you feel
any small bumps or irregularities, this could inhibit proper
loading of the disc. To remove the bumps, rub the inside edge of
the hole and outside edge of the disc with a ballpoint pen or other
such instrument, then insert the disc again.

Irregular Shaped Discs

Be sure to use round shape discs only for this unit and never use
any special shape discs.
Use of special shape discs may cause damage to the mechanism.
