Handling Compact Discs - Kenwood KDC-7090R Instruction Manual

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
(i.e., 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 above the
fascia panel (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 whilst, and put them
back in their cases. Do not stack CDs that
have been removed from their cases or prop
them against something.
Cleaning CDs
If a CD has become dirty, wipe it off gently
using a commercially available cleaning cloth
or a soft cotton cloth, starting from the
centre 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 whilst playing.
Remove burrs using a ballpoint pen or a
similar utensil.
