i The volume of external audio sources is ex-
tremely variable. It is possible that a device con-
nected as an external audio source will sound
quieter or louder in the vehicle or that the usual
maximum volume cannot be achieved. On cer-
tain devices the volume can be set separately. In
this case, start at a moderate volume and in-
crease it slowly. In this way, you can determine
whether the system is capable of playback with-
out distortion, even at high volume.

i When playing copied discs, problems may
occur with the playback.

ers are available. Due to this variety we cannot
guarantee that the system will be able to play

! 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.
