Notes on copyright
MP3 or WMA tracks that you create or play
back are generally subject to copyright
protection 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
Discs with copy protection are not
compatible with the audio CD standard and
therefore may not be able to be played by
COMAND.
There may be playback problems when
playing copied discs. There is a wide range of
data carriers, burning software and burners
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
storage 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. In such cases,
COMAND then switches to the next disc.
This is normal system behavior and does
not mean that there is a malfunction.
! Do not affix stickers or labels to the discs.
They could peel off and damage the drive.
The drive is designed to hold discs which
comply with the EN 60908 standard.
Therefore, you can only use discs with a
maximum thickness of 1.3 mm.
