Handling discs
When holding discs of any type, take care not to leave
fi ngerprints, dirt or scratches on the disc surface. Hold
the disc by its edge or by the center hole and edge.
Damaged or dirty discs can affect playback per for mance.
Take care also not to scratch the label side of the disc.
Although not as fragile as the recorded side, scratches
can still result in a disc becoming unusable.
Should a disc become marked with fi ngerprints, dust,
etc., clean using a soft, dry cloth, wiping the disc lightly
from the center to the outside edge as shown in the
diagram below.
Wipe lightly from the
center of the disc using
straight strokes. Don’t wipe the disc surface
using circular strokes.
If necessary, use a cloth moistened in alcohol, or a
commercially available CD/DVD cleaning kit to clean a
disc more thor ough ly. Never use benzene, thinner or
other cleaning agents, including products designed for
cleaning vinyl records.
Storing discs
Although CDs and DVD discs are more durable than
vinyl records, you should still take care to handle and
store discs correctly. When you're not using a disc,
return it to its case and store upright. Avoid leaving discs
in excessively cold, humid, or hot environments (including
under direct sun light).
Don't glue paper or put stickers onto the disc, or use
a pencil, ball-point pen or other sharp-tipped writing
in stru ment. These could all damage the disc.
For more detailed care information, see the in struc tions
that come with discs.
Do not load more than one disc into the player.
Discs to avoid
Discs spin at high speed inside the player. If you can see
that a disc is cracked, chipped, warped, or otherwise
damaged, don't risk using it in your play er. You could
end up dam ag ing the unit.
This unit is designed for use with conventional,
fully circular discs only. Use of shaped discs is not
rec om mend ed for this product.
Cleaning the pickup lens
The DVD player’s lens should not become dirty in normal
use, but if for some reason it should mal func tion due to
dust or dirt, consult your nearest MARANTZ-authorized
service center. Al though lens cleaners for CD players
are com mer cial ly available, we do not recommend using
them since some may damage the lens.
Problems with condensation
Condensation may form inside the player if it is brought
into a warm room from outside, or if the temperature of
the room rises quickly. Although the condensation won’
t damage the player, it may tem po rari ly impair its per-
for mance. For this reason you should leave it to adjust
to the warmer tem per a ture for about an hour before
switching on and using it.
