Handling Compact Discs
Playing a CD that is dirty, scratched or
warped can cause the sound to skip and
the unit to operate incorrectly, resulting in
worsened sound quality. Take the
following precautions to prevent your CDs
from getting scratched or damaged.
Handling CDs
• Do not touch the recorded side of the CD (the
side opposite the label) when holding it.
• The reflective film on a CD-R or a CD-RW is more
fragile than that on an ordinary music CD, and may
peel off if scratched. Fingerprints on a CD-R or CD-
RW are also more likely to cause skipping when
the disc is played. For these reasons, handle the
disc very carefully. Detailed handling instructions
will appear on the CD-R or CD-RW package: read
this information carefully before using the disc.
• Do not stick tape on either side of the CD.
Storing CDs
• Do not store CDs in areas exposed to direct
sunlight (such as a car seat or the dashboard) or
other hot places.
• A CD-R or CD-RW is more susceptible than a
music CD to damage from high temperatures and
humidity, and in some cases, may become
unusable if left in the car for long periods of time.
• Remove CDs from the unit when not listening to
them for a while, and put them back in their
cases. Do not pile up CDs that are removed from
their cases or prop them against something.
Cleaning CDs
I
f a CD has gotten dirty, wipe it off gently using a
commercially available cleaning cloth or a soft
cotton cloth, starting from the center of the disc
and moving outward. Do not clean CDs with
conventional record cleaners, anti-static formulas,
or chemicals such as paint thinner or benzene.
Checking New CDs for Burrs
When playing a new CD for the first time, check
that there are not any burrs stuck to the perimeter
of the disc or in the central hole. CDs with burrs
stuck on them may not load properly or may skip
while playing. Remove burrs using a ballpoint pen
or a similar utensil.
Do Not Load CD Accessories
Do not use commercially available CD accessories
that can be loaded into the CD slot, such as
stabilizers, protective sheets, or CD cleaning discs,
since they can cause the unit to malfunction.
Do Not Use Special Shape CDs
• Be sure to use round shape CDs only for this unit
and do not use any special shape CDs. Use of
special shape CDs may cause the unit to
malfunction.
• This unit can only play the CDs with
.
It may not correctly play disks which do not have
the mark.
• CD-Rs and CD-RWs which have not undergone
finalization processing cannot be played. (For
more information on finalization processing, refer
to the manual for your CD-R/CD-RW writing
software or CD-R/CD-RW recorder.) Additionally,
depending on the recording status, it may prove
impossible to play certain CDs recorded on CD-R
or CD-RW.
Do Not Use CDs with Sticker on the
Labeled Side
Do not use the CD with the label sticker stuck on
it.
Using such a CD may cause the CD to be
deformed and the sticker to peel off, resulting in
malfunction of the unit.
