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 for-
mat used, up to 128 characters are possi-

i
CD media, CD burning software and
CD writers are available in great vari-
ety. 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 re-
sult 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 m ay not b e a bl e to pl ay them a t al l.
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.
