Compatible file systems and compres-

The following compression methods are
compatible:

MP3

WMA
Permissible bit and sampling rates

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 you know the applicable copy-
right regulations and that you comply with
these.
If you own these rights yourself, e.g. for
your own compositions and recordings, or
the copyright holder has granted you per-
mission, these restrictions do not apply.
iThe audio system does not support ID3 tags.
iThis format is generally known as “MP3”.
iIf music files, created with different com-
pression methods, in addition to MP3 files, are
stored together on a disc, the loading process
may take longer before the first track is played.
iOnly use MP3 tracks with a bit rate of at
least 128 kbit/s or higher and a sampling rate of
at least 44.1 kHz or higher. Smaller rates can
cause a noticeable deterioration in sound quali-
ty. This is especially the case if you have activat-
ed the surround sound* function.
