MP3 MODE
In addition to playing normal audio CDs, the
radio is also capable of playing CD-ROMs on
which MP3 format compressed audio files
are recorded. The radio works according to
the methods described in chapter “5” when
an ordinary audio CD is inserted.
The use of good quality supports burnt at the
slowest possible speeds is recommended for
optimum quality.
The files on the CD MP3 are in folders, with
sequential lists of all the folders containing
MP3 trackts (folders and sub-folders are all
on the same level) and 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 in ac-
cordance with ISO9660 Specification;
❍
the music files should have extension
“.mp3”: files with other extensions can-
not be played;
❍
the sampling frequency range that can
be reproduced is: 44.1 kHz, stereo (96
to 320 kbit/s) - 22.05 kHz, mono or
stereo (32 to 80 kbit/s);
❍
tracks with variable bit-rates can be re-
produced.
IMPORTANT Track names must not contain
the following characters: spaces, ‘
(apostophes), (e) (open and close brack-
ets). When a CD MP3 is being burned,
make sure that the file names do not con-
tain these characters; otherwise, the car ra-
dio will not be able to play those tracks.
