Safety notes
$
Risk of injury
The CD changer is a class 1 laser product. If
the casing is opened or is faulty or damaged,
there is a danger that invisible laser radiation
may damage your eyes or other people's
eyes.
Do not open the casing. The unit contains no
parts on which you can carry out mainte-
nance. For safety reasons, have any neces-
sary maintenance work carried out by
qualified aftersales technicians only.

Risk of accident
In order to avoid distraction which could lead
to an accident, the driver should insert or
eject CDs with the vehicle at a standstill and
operate Audio 20 only if permitted by road,
weather and traffic conditions.
Bear in mind that at a speed of just 30 mph
(50 km/h), your vehicle is covering a dis-
tance of 44 feet (14 m) every second.

Multisession CDs
For multisession CDs, the content of the first
session determines how Audio 20 will pro-
cess the CD.
If the first session contains data in audio CD
format and the second session contains MP3
tracks, Audio 20 will treat the CD as a con-
ventional audio CD. This means that it is not
possible to access the MP3 tracks.
If the first session contains MP3 tracks, for
example, and the second session contains
data in audio CD format, Audio 20 will not
treat the disc as a conventional audio CD.
This means that it is only possible to access
the MP3 tracks.
File structure of a disc
When you create an MP3 disc, the MP3
tracks can be organized in folders. A folder
can also contain subfolders. A disc
can contain a maximum of 255 folders. Each
folder can contain a maximum of 255 tracks
and 255 subfolders.
A disc can contain a maximum of 500 tracks.
The maximum directory depth for MP3 CDs
must not exceed 8 levels. Files in lower levels
are ignored.
Track and folder names
When you create an MP3 disc, you can assign
names to the MP3 tracks and folders.
Audio 20 uses these names for the display in
MP3 mode. Audio 20 does not display files
that are not supported.
