Audio DVDs differ from recordable DVD-
R and DVD-RW discs.
Data on audio DVDs are stored either in
uncompressed format or in lossless
compressed format. The sound quality on
audio DVDs is therefore better than on
recordable DVDs that contain MP3 data
because the MP3 format uses a lossy type of
compression.
You cannot delete data from or record
additional data to commercially available,
prerecorded audio DVDs.
Please note the following information about
CDs/DVDs and pay special attention to the
notes on copied and/or self-written CDs/
DVDs.
i
The last track on many audio DVDs does
not contain audio data. COMAND will then
change to the next medium. This behavior
is system-induced and does not indicate a
system malfunction.
Notes about CDs/DVDs
i
Audio CDs with copy protection are not
compatible with the CD audio standard and
therefore may not be able to be played by
COMAND.
There may be playback problems when
playing copied discs.
There is a large variety of discs, disc-writing
software and writers available. This variety
means that there is no guarantee that the
system will be able to play discs that you
have written/copied yourself.
There may be playback problems if you use
CD-R or CD-RW type discs you have copied
yourself with a storage capacity of more
than 700 MB. These CDs are not
compatible with currently applicable
standards.
!
Do not affix stickers or labels to the discs.
These could peel away and damage
COMAND. COMAND is designed to hold
discs which comply with the IEC 60908
standard. You can therefore only use discs
with a maximum thickness of 1.3 mm.
If you insert thicker discs, e.g. those that
contain data on both sides (DVD on one
side and audio data on the other), they
cannot be ejected and can damage
COMAND.
Do not use CDs with a diameter of 8 cm.
Attempting to play discs with a diameter of
8 cm or playing such discs with an adapter
may cause damage COMAND.
Such damages are not covered by the
Mercedes-Benz Limited Warranty.
Only use round discs with a diameter of
12 cm.
Notes about handling CDs/DVDs
R
Only hold discs by the edge.
R
Handle discs carefully to prevent playback
problems.
R
Avoid getting scratches, fingerprints and
dust on discs.
R
Clean discs from time to time with a
commercially-available cleaning cloth. Do
not wipe them with a circular motion, but
only in straight lines from the center
outwards.
R
Only use a pen designed for such a purpose
to label discs.
R
Place discs back in their boxes after use.
R
Protect discs from heat and direct sunlight.
Inserting/ejecting CDs and DVD
G
Observe Safety notes, see page 162.
i
If the CD/DVD has a printed side, this
must face upwards when the CD/DVD is
inserted. If neither side is printed, the side
to be played should face downwards.
