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.
To guarantee optimal playback quality it is
advisable to use good quality CDs mastered at the
lowest speed possible.
The files on an MP3 CD are structured in folders
that create lists of all the folders containing MP3
tracks (folders and subfolders are all displayed on
the same level); the folders that do not contain
MP3 tracks cannot be selected.The operating conditions and specifications for
playing MP3 files are as follows:
❒the CD-ROMs used should be burnt according to
ISO 9660 standard;
❒the music files must have an ".mp3" extension:
files with a different extension cannot be played;
❒the following sampling frequencies can be
played: 44.1 kHz, stereo (96 to 320 kbit) -
22.05 kHz, mono or stereo (32 to 80 kbit);
❒tracks with a variable bit-rate can be
reproduced.

Note
The names of tracks must not contain 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.
Note
When the function is activated the radio may take
a few seconds to start playing. Whilst checking the
disc the display will show "CD Reading". If no
MP3 files are detected, the radio will resume
playing the audio session from the point where it
was interrupted.

DISPLAY INFORMATION
ID3-TAG information display
In addition to the information relating to the time
elapsed, the name of the folder and the name of
the file, the radio is also capable of display ID3-
TAG information relating to the Track Title, Artist
and Author.
The name of the MP3 folder shown on the display
corresponds to the name with which the folder was
stored on the CD, followed by an asterisk.
Example of a complete MP3 folder name: BEST
OF *.
When ID3-TAG data is chosen to be displayed
(Title, Artist, Album) that has not been recorded
for the track played, the information will be
replaced by that relating to the name of the file.
