Only use tracks with a bit rate of at least
128 kbit/s and a sampling rate of at least
44.1 kHz. Lower rates may cause a notice-
able deterioration in quality. This is espe-
cially the case if you have activated a sur-
round sound function.
Notes on copyright
MP3 or WMA tracks that you create or play
back are generally subject to copyright pro-
tection in accordance with the applicable
international and national regulations.
In many countries, reproductions, even for
private use, are not permitted without the
prior consent of the copyright holder.
Make sure that you know about the applicable
copyright regulations and that you comply
with these.
If you own these rights yourself, e.g. for your
own compositions and recordings, or if the
copyright holder has granted you permission,
these restrictions do not apply.
Notes on CDs/DVDs
! COMAND Online is designed to play discs
which comply with the EN 60908 standard.
Therefore, you can 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 can-
not be ejected and can damage the device.
Only use round discs with a diameter of
12 cm. Do not use discs with a diameter of
8 cm, even with an adapter.
Discs with copy protection are not compati-
ble with the CD standard and therefore may
not be able to be played by COMAND Online.
You may encounter playback problems when
playing copied discs. There is a wide range of
data carriers, disc-writing software and writ-
ers available. This variety means that there is
no guarantee that the system will be able to
play discs that you have copied yourself.
There may be playback problems if you play
CDs that you have copied yourself with a stor-
age capacity of more than 700 MB. CDs of
this type do not conform to the currently
applicable standards.
i
On many DVD audio discs, the last track
does not contain any music. If
COMAND Online therefore switches to the
next disc, it is normal system behaviour and
does not mean that there is a malfunction.
i
COMAND Online is able to play back
audio CDs in multichannel audio format.
