Tips on handling CDs

Handle CDs carefully to prevent
interference during playback.

Avoid scratches, fingerprints and dust
on the CDs.

Do not write on CDs or apply any labels
or other material to them.

Clean CDs from time to time with a
commercially available cleaning cloth.
Never wipe the CD in a circular motion;
instead, wipe it in a straight line start-
ing in the center and moving outward.
Do not use solvents, anti-static sprays,
etc. for cleaning.

Replace the CD in its case after use.

Protect CDs from heat and direct
sunlight.MP3 notes
The CD changer* can play audio CDs as
well as CDs with MP3 files.
Information on MP3 data carriersCompatible MP3 data carriers
The CD changer can read the following
data carriers in MP3 mode:

CD-DA

CD-R

CD-RW
Compatible file systems and compres-
sion methods
Use Romeo or Joliet. Depending on file
format used, up to 128 characters are
possible
The following compression methods are
compatible:

MP3

WMA

WAV
iCD media, CD burning software and
CD writers are available in great variety. Due to
this variety, it cannot be guaranteed that the CD
changer will be able to play every user-written
CD.
The burning process can lead to data errors and
aging of the medium may result in data loss.
Therefore, the CD changer may be restricted in
its ability to play MP3 data carriers; it may play
them with reduced sound quality, or it may not
be able to play them at all.
Problems may be encountered during playback
of user-written CDs with a storage capacity of
more than 700 MB. These CDs do not meet valid
standards as of this printing.
