CDs
The presence of dirt, scratches or distortions on the
CDs may cause skipping while it is playing and poor
sound quality. For optimal playback conditions, follow
these guidelines:
❒only use CDs with the following mark;
RADIO
223
❒clean every CD thoroughly removing any fingermarks
or dust using a soft cloth. Hold CDs by the
circumference and clean them from the centre
towards the edge;
❒never use chemicals (e.g. antistatics or thinners or
sprays) for cleaning as they may damage the surface of
the CDs;
❒after listening place CDs back in their boxes to avoid
them from being damaged;
❒do not expose CDs to direct sunlight, high
temperatures or moisture for long periods;
❒do not stick labels on the CD surface or write on the
recorded surface with pencils or pens.
❒do not use CDs that are very scratched, flawed,
distorted, etc. Using discs like these will result in
malfunctions or damage to the player;
❒The use of original CD media is required for the best
quality audio production. Correct operation is not
guaranteed when CD-R/RW media are used that
were not correctly mastered and/or with a maximum
capacity above 650 Mb;
❒Do not use commercially available protective sheets
for CDs or discs with stabilisers, etc. 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 reproduce it.
The CD player cannot be guaranteed to play all
protected discs. The fact that the CD is protected
from being copied is often shown in very small letters
or is just legible on the CD cover itself where it may,
for example, say “COPY CONTROL”, “COPY
PROTECTED”, “THIS CD CANNOT BE PLAYED
ON A PC/MAC”, or it may be identified through the
use of symbols, such as, for example:
❒The CD player is capable of reading most
compression systems currently in use (e.g.: LAME,
BLADE, XING, FRAUNHOFER) but, following the
development of these systems, the reading of all
compression formats is not guaranteed.

MP3 CD PLAYER
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”.
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
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.
