‘album’, which can be divided into a maxi-
mum of nine groups. A group may contain,
for example, music of different sound qual-
ities (stereo and multi-channel formats) or
bonus tracks. Each group can include up to
99 tracks. If a DVD audio only comprises
one audio format, the “Group” menu
item(s) cannot be selected.

proximately 3 MPH, the picture will switch
off automatically in DVD video mode.

the display: “In order not to distract you
from the traffic situation, the picture is fad-
ed out while the vehicle is in motion.”.

mately 3 MPH, the picture switches back

i When playing copied discs, problems may
occur with the playback.
A wide variety of disc-writing software and writ-
ers are available. Due to this variety we cannot
guarantee that the system will be able to play
discs that you have written/copied yourself
! Do not attach stickers or labels of any kind
to discs. They may come loose and damage
COMAND. Labels may also cause the disc to
bend, which may result in reading errors and
problems with disc recognition.
! COMAND has been designed for discs meet-
ing the requirements of standard EN 60908.
Therefore, only discs with a maximum thickness
of 1.3 mm can be used.
If a thicker disc is inserted, e. g. one which stores
data on both sides, (DVD on one side, audio data
on the other side), this cannot be ejected and
COMAND will be damaged.
Do not use 8 cm diameter discs, not even with an
adapter.
Only use round, 12 cm diameter discs.

Only touch the discs at the edges.

Handle discs with care in order to pre-
vent malfunctions during playback.

Avoid scratching, leaving fingerprints
and dust on the discs.

Clean the discs occasionally with a
commercially available cleaning cloth.
Always wipe in a straight line from the
inside outwards, never in a circular mo-
tion.

The discs must only be labelled using
pens specially designed for this pur-
pose.

lems may occur when you play such DVDs.

ed that they have been made to the PAL or NTSC
TV standard.
