Care of Your CDs
If playing a CD-R, the sound quality can be reduced due
to CD-R or CD-RW quality, the method of recording, the
quality of the music that has been recorded, and the way
the CD-R or CD-RW has been handled. Handle them
carefully. Store CD-R(s) or CD-RW(s) in their original
cases or other protective cases and away from direct
sunlight and dust. The CD or DVD player scans the
bottom surface of the disc. If the surface of a CD is
damaged, such as cracked, broken, or scratched, the CD
does not play properly or not at all. Do not touch the
bottom side of a CD while handling it; this could damage
the surface. Pick up CDs by grasping the outer edges or
the edge of the hole and the outer edge.
3-92

If the surface of a CD is soiled, take a soft, lint free
cloth or dampen a clean, soft cloth in a mild, neutral
detergent solution mixed with water, and clean it.
Make sure the wiping process starts from the center
to the edge.
Care of Your CD and DVD Player
Do not add any label to a CD, it could get caught in the
CD or DVD player. If a CD is recorded on a personal
computer and a description label is needed, try labeling
the top of the recorded CD with a marking pen
instead.
The use of CD lens cleaners for CDs is not advised,
due to the risk of contaminating the lens of the CD optics
with lubricants internal to the CD and DVD player
mechanism.
Notice:If a label is added to a CD, or more than
one CD is inserted into the slot at a time, or an
attempt is made to play scratched or damaged CDs,
the CD player could be damaged. While using the
CD player, use only CDs in good condition without
any label, load one CD at a time, and keep the
CD player and the loading slot free of foreign
materials, liquids, and debris.
If an error displays, see “CD Messages” later in this
