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 (located
behind the detachable front panel) with a pointed object
such as a ball-point 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 centre 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 ball-point 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.
Installation Location
Make sure the CDM-7857/CDM-7854/CDE-7853 will not
be installed in a location subjected to:
• Direct sun and heat
• High humidity and water
• Excessive dust
• Excessive vibrations
Handling the Detachable Front Panel
• Do not expose to rain or water.
• Do not drop or apply shock.
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 centre
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.
