ALPINE DHA-S690 68-09359Z17-A (EN)
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
operational problems. We recommend not using these accessories
on discs played in Alpine DVD changers.

Installation Location
Make sure the DHA-S690 will not be installed in a location
subjected to:
• Direct sun and heat
• High humidity and water
• Excessive dust
• Excessive vibrations
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 DVD changer 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.
PRECAUTIONS
Product Cleaning
Use a soft dry cloth for periodic cleaning of the product. For
more severe stains, please dampen the cloth with water only.
Anything else has the chance of dissolving the paint or damaging
the plastic.
Temperature
Do not operate your unit in ambient temperature above +60°C
(+140°F) or below -10°C (+14°F).
Moisture Condensation
You may notice the disc playback sound wavering due to
condensation. If this happens, remove the disc from the player
and wait about an hour for the moisture to evaporate.
Damaged Disc
Do not attempt to play cracked, warped, or damaged discs.
Playing a bad disc could severely damage the playback
mechanism.
Maintenance
If you have problems, do not attempt to repair the unit yourself.
Return it to your Alpine dealer or the nearest Alpine Service
Station for servicing.
New Discs
When a newly purchased disc is inserted into the changer
magazine, the disc may fail to play after initial loading.
This is caused by small bumps around the centre hole and outside
of the disc, which prevent stable loading into the correct position.
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.
•The mechanism automatically prevents this type of disc from
playing as a protective measure. This is not an indication of faulty
operation.
Irregular Shaped Discs
Be sure to use round shaped discs only for this unit and never use
any special shaped discs.
Use of special shaped discs may cause damage to the mechanism.
