Safety instructions
WarningG
In order to avoid distraction which could
lead to an accident, the driver should insert
CDs with the vehicle at a standstill and
operate the audio system only if permitted
by road, weather and traffic conditions.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your car covers a
distance of 44 feet (approximately 14 m)
every second.
WarningG
The CD drive is a Class 1 laser product.
There is a danger of invisible laser radiation
when you open or damage the cover.
Do not remove the cover. The CD drive does
not contain any parts which can be serviced
by the user. For safety reasons, have any ne-
cessary service work performed by qualified
personnel.
Tips on data storage media
!
Do not attach labels of any type to the
CD. They may become detached and
damage the drive.
!
Your CD drive has been designed to
play CDs which correspond to the IEC
60908 standard. Therefore only CDs
not exceeeding a thickness of 1.3 mm
can be used.
If you insert thicker data carriers, e.g.
ones that have data on both sides (one
side with DVD data, the other side with
audio data), they will become stuck and
damage the drive.
Do not play single CDs (80mm) with an
adapter. An adapter could become
stuck and damage the drive. Only use
12 cm diameter CDs.

66 Audio
MP3 CD operation
Only touch the CD on the edges.
Clean the CD with a dry, lint-free cloth.
Wipe the CD a straight line from the
center. Never wipe the CD in a circular
motion.
Do not use rubbing alcohol or solvents
to clean CDs.
Do not expose the CDs to cold, heat or
direct sunlight.
Do not write or put labels on CDs.Permissible MP3 CDs
In MP3 mode COMAND can read CD-R and
CD-RW CDs.
Permissible file systems
The permitted file system for COMAND is
ISO9660/Joliet for CD-R and CD-RW.
Multi session CDs
Multi session CDs include mixed file types
(e.g. MP3 and audio CD) in either
successive or random order on the disc. In
MP3 mode, COMAND will integrate audio
CD tracks into the disc’s folder structure.
The CD audio track folder will appear first
followed by folders containing MP3 tracks.

i
CDs, software and hardware for writing
audio data to CDs vary widely.
Therefore, we cannot guarantee that
COMAND will be able to play every
user-written CD. Problems may also be
encountered during playback of user-
written CDs with a storage capacity of
more than 700 MB.
