Precautions

PRECAUTIONS
Temperature
Be sure the temperature inside the vehicle is between
+60°C (+140°F) and –10°C (+14°F) before turning your
unit on.
Proper Handling
Handle your disc as shown. Do not drop the disc while
handling. Hold the disc so you will not leave fingerprints
on the surface. If the surface is scratched, it may cause the
pickup to skip. Do not affix tape, paper, or gummed labels
on the disc. Do not write on the disc.
Keep Your Discs Clean
Fingerprints, dust, or soil on the surface could cause the
pickup 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
Various disc accessories for protecting the surface of the
disc and improving sound quality are available on the
market.
However, many of them will increase the thickness and/or
diameter of the disc. Using such accessories may place the
disc beyond the specified size limitations and cause the
changer to malfunction. Because of the high precision
electronics of the DHA-S680 and the highly stable
mechanism, these accessories are not necessary and
therefore not recommended for use with discs placed in
the DHA-S680.
Caution for 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 center 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.
NOTE
The mechanism automatically prevents this type of disc from
playing as a protective measure. This is not an indication of
faulty operation.

Damaged Disc
Do not attempt to play cracked, warped, or otherwise
damaged discs.
Playing a bad disc could severely damage the playback
mechanism.
Storage
When not in use, place your discs in their individual cases
and store them in a cool place away from the sun, heat,
and dust.
Irregular Shaped Discs
Make sure the discs you use in this unit do not have any
irregularities. The outer and inner edges should be round
and smooth. Use of irregularly shaped discs may cause
damage to the mechanism.
