❒Never use CDs that are very scratched, cracked, distorted, etc.
Their use could cause damage to the player or make it
malfunction;
❒to achieve the best quality audio reproduction we recommend
the use of original CD media. Correct operation is not
guaranteed when CD-R/RW media are used that were not
correctly burnt and/or with a maximum capacity above 650
Mb;
❒do not use commercially available protective sheets for CDs or
discs with stabilisers as they could get stuck in the internal
mechanism and damage the disc;
❒if a copy-protected CD is used, it may take a few seconds before
the system starts to play it. The CD player cannot be guaranteed
to play all protected discs. The presence of copy protection is
often indicated in small or difficult to read letters on the cover of
the CD; like, for example, "COPY CONTROL", "COPY
PROTECTED", "THIS CD CANNOT BE PLAYED ON A PC/MAC"
or may be identified through the use of symbols, such as, for
example:
❒The CD player is able to read most of the compression systems
currently on the market (e.g.:LAME, BLADE, XING,
FRAUNHOFER) but as these systems are continually evolving,
playback of all compression formats is not guaranteed.

MP3 CD PLAYER
INTRODUCTION
This section 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 the “Radio” and “CD MP3
Player” sections.
NOTE MPEG Layer-3 audio decoding technology licensed from
Fraunhofer IIS and Thomson multimedia.
MP3 MODE
In addition to playing regular audio CDs, the radio is also able to
play CD-ROMs on which audio files have been stored using the
MP3 compression format. The radio operates as described in the
“CD Player” section 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 by folder, creating 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 the 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/s) - 22.05 kHz, mono or stereo (32 to 80
kbit/s);
❒tracks with a variable bit-rate can be reproduced.
NoteThe names of tracks must not contain the following
characters: spaces, ' (apostrophes), ( and ) (open and close
brackets). When burning an MP3 CD, make sure that the names of
the files do not contain these characters; if they do, 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 switch to the MP3 session whilst
playing by holding the MEDIA button down for more than 2
seconds.
NoteWhen 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.
