Multisession CDs
For multisession CDs, the content of the first
session determines how COMAND will proc-
ess the CD. COMAND plays only one session
and gives priority to the audio CD session.
If possible, use COMAND to play only CDs
which were writte ninone session.
File structure of a disc
Whe nyou create a disc with compressed
music files, the tracks can be organised in
folders. Afolder can also contain subfolders.
A disc can contain amaximum of 255 folders.
Each folder can contain a maximum of 255
tracks and 25 5subfolders. Adisc can contain
a maximum of 4,000 tracks.
The disc may contain no more than eight
directory levels. Files beyond the eighth level
will not be recognised by the system.
Track and file names
When you create a disc with compressed
music files, you can assign names to the
tracks and folders.
COMAND uses these names accordingly for
the display. Folders which contain data other
than MP3 or WMA tracks are not displayed by
COMAND.
If MP3 or WMA files are stored in the highest
directory itself, the highes tdirectory will also
be treated as a folder .COMAND will then
show these directory names as folder names. You must observe the following when assign-
ing track names:
R
track names must have at least one char-
acter.
R track names must have the extension
"mp3" or "wma".
R there must be a full stop between the track
name and the extension.
Example of a correct track name:
Track1.mp3
i COMAND does not support ID3 tags.
Permissible formats
COMAND supports the following formats:
R MPEG1 Audio-Layer3( MP3)
R Microsoft Windows Media Audio V2, V7, V8
and V9 (WMA)
R music files in AAC format, but not copy-
protected iTunes music files with the exten-
sion "m4p".
i If, as well as MP3 files, there are music
files in these audio formats stored on the
disc, loading may require longer before the
first track is played.
i The MP3 audio encoding method is under
licence from Fraunhofer IIS (Institut Integ-
rierte Schaltungen –Institute for Integrated
Circuits) and Thomson.
Permissible bi tand sampling rates
MP3
COMAND supports MP3 files of the following
types:
R fixed and variable bit rates from 32 kbit/s
to 320 kbit/s
R sampling rates of 8 kHz to 48 kHz
WMA
COMAND supports WMA files of the following
types:
R fixed bit rates of 5 kbit/s up to

COMAND does no
tsuppor tWMA files of the
following types:
R DRM (Digital Rights Management) encryp-
ted files
R variable bit rate
R WMA Pro
R 5.1 Surround
i Only use tracks with a bit rate of at least
128 kbit/s and a sampling rate of at least
44.1 kHz. Lower rates can cause a notice-
able deterioration in quality.
When the Bang &Olufsen sound system*
is switched on (Y page 68), the bit rate for
MP3 tracks should be at least 224 kbit/s.
Notes on copyright
MP3 or WMA tracks that you create or play
back are generally subject to copyright pro-
tection in accordance with the applicable
international and national regulations.
In many countries, reproductions, even for
private use, are not permitted without the
prior consen tofthe copyright holder.
Ensure that you know about the applicable
copyright regulations and that you comply
with these.
If you own these rights yourself, e.g. for your
own compositions and recordings, or if the
copyright holder has granted you permission,
these restrictions do not apply.
Notes on CDs/DVDs
i Discs with copy protection are not com-
patible with the audio CD standard and
therefore may not be able to be played by
COMAND.
There may be playback problems when
playing copied discs. There is a wide range
of data carriers, writing software and writ-
ers available. This variety means that there
is no guarantee that the system will be able
to play discs that you have copied yourself.
There may be playback problems if you play
CDs that you have copied yourself with a
storage capacity of more than 700 MB. CDs of this type do not conform to currently
applicable standards.
i In many DVD audio albums, the last track
does not contain any music and the Rear
Seat Entertainment System switches to the
next disc. This is normal system behaviour
and does not mean that there is a malfunc-
tion.
! Do not affix stickers or labels to the discs,
as they could peel off and damage
COMAND. Stickers can cause the disc to
bend, which can result in read errors and
disc recognition problems.
! COMAND is designed to accommodate
discs which comply with the EN 60908
standard. You can therefore only use discs
with a maximum thickness of 1.3 mm.
If you insert thicker discs, e.g. those that
contain data on both sides (DVD on one
side and audio data on the other), they can-
not be ejected and can damage COMAND.
Use round discs with a diameter of 12 cm.
Do not use discs with a diameter of 8 cm,
even with an adapter.
i COMAND can play back audio CDs in mul-
tichannel audio format.
Notes about handling CDs/DVDs R
Only hold discs by the edge.
R Handle discs carefully to prevent playback
problems.
R Avoid getting scratches, fingerprints and
dust on discs.
R Clean discs from time to time with a com-
mercially available cleaning cloth. When
cleaning CDs, you should wipe in straight
lines from the centre outwards rather than
in a circular motion.
R Only use a pen specifically made for label-
ling discs.
R Place discs back in their cases after use.
R Protect discs from heat and direct sunlight. Audio
