General notes on MP3
The music that can be played when your
unit is in MP3 mode is generally copy-
right-protected under applicable interna-
tional and national laws. In several
countries, the reproduction of copy-
righted material is not permitted, even if
only for personal use, without the
express prior consent of the copyright
holder. Please check the current copy-
right laws for your country and comply
with them. These restrictions naturally
do not apply to your own compositions
and recordings, or for recordings for
which authorisation has been obtained
from the copyright holder.
Creating an MP3 storage
medium
A maximum of 63 folders, each of
which can contain up to 50 tracks, can
be stored on a storage medium. How-
ever, a maximum of 1000 tracks per
medium are supported. If a folder con-
tains more than 50 tracks, a second
folder will be created automatically
which can also contain up to 50 tracks.
Only folder names with 45 characters
or fewer can be displayed. Only track
names with 63 characters or fewer can
be displayed.
Only MP3 tracks stored on a storage
medium in compliance with ISO 9660
can be played.
If the artist’s name and track title are
to be displayed, an ID3 tag must be
added to the MP3 file. This unit sup-
ports versions ID3v1 and ID3v2.
The ID3 tag can only be displayed if
the corresponding track is being
played. The file name appears first
(trackname.MP3).
The display of artist’s name and track
title is restricted to a total maximum
length of 63 characters.
The MP3 formats MPEG1 and MPEG2
Layer3 are supported by the unit.
Fixed and variable bit rates of 8 - 320
kbps and scan rates of 16-48 kHz are
supported. We recommend the use of
the Fraunhofer MP3 Encoder when
creating MP3 files.
We recommend a bit rate of at least
160 kbps for compressing MP3 files.
It should be noted that with MP3 files
having a variable bit rate, the display
of the elapsed playing time may
deviate from real time.
In the case of a mixed-mode medium
(partly conventional audio tracks and
partly data), only the audio tracks are
played back. The data part is not
played back, even if MP3 tracks are
included.
