INTRODUCTION
This chapter only describes the variants regarding the
operation of the CD MP3 player: as far as the operation
of the radio is concerned, refer to the description in
chapters “Radio” and “MP3 CD Player”.

MP3 MODE
In addition to playing regular audio CDs, the radio is also
able to play CD-ROMs on which audio files have been
recorded using the MP3 compression format. The radio
functions as described in the “CD Player” chapter when
an ordinary audio CD is inserted.
The use of good quality media burned at the slowest
possible speeds is recommended for optimum quality.
The files on an MP3 CD are structured in folders that
create lists of all the folders containing MP3 tracks
(folders or subfolders are all displayed on the same
level); the folders that do not contain MP3 tracks cannot
be selected.The specifications and operating conditions for playing
MP3 files are the following:
❒the CD-ROMs used should be mastered in
accordance with the ISO 9660 standard;
❒the music files should have the extension “.mp3”: files
with a different extension will not be reproduced;
❒The sampling frequencies that can be reproduced are:
44.1 kHz, stereo (from 96 to 320 kbit/s) – 22.05 kHz,
mono or stereo (from 32 to 80 kbit/s);
❒tracks with a variable bit-rate can be reproduced.
IMPORTANT The track names must not include the
following characters: spaces, ‘ (apostrophes), ( and )
(open and close brackets). During the mastering of a
MP3 CD, make sure that the names of the files do not
contain these characters; if not, the radio will not be able
to play the tracks involved.
SELECTING MP3 SESSIONS ON HYBRID
DISCS
If a hybrid disc is inserted (Mixed Mode, Enhanced, CD-
Extra) also containing MP3 files, the radio automatically
starts playing the audio session. It is possible to move to
the MP3 session whilst playing by keeping the MEDIA
button pressed for more than 2 seconds.
