Fixed and variable bit rates up to
320 kbit/s


Sampling rates of 24 kHz – 48 kHzNotes on copyright
The music tracks that you create for MP3
mode and can play back in MP3 mode are
generally subject to copyright protection in
accordance with the applicable interna-
tional and national regulations.
In many countries, reproductions are not
permitted without the prior consent of the
copyright holder, not even for private use.
Make sure that you know 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

Notes about audio DVD operation
COMAND can playback commercially

i
This format is generally known as “MP3”.
i
Only use MP3 tracks with a bit rate of at
least 128 kbit/s and a sampling rate of at least
44.1 kHz. Smaller rates can cause a noticeable
deterioration in sound quality. This is especially
the case if you have activated a surround sound

and DVD-RW discs.

Only hold discs by the edge.


Handle discs carefully to prevent play-
back problems.


Avoid getting scratches, fingerprints
and dust on discs.


Clean discs from time to time with a
commercially-available cleaning cloth.
Do not wipe them with a circular mo-
tion, but only in straight lines from the
center outwards.


Only use a pen designed for such a pur-
pose to label discs.


Place discs back in their boxes after
