CDs. When playing MP3 CDs, only the first
99 tracks will be played in succesive order.
After that, playback will begin with track 1
of the MP3 CD. Folder selection is not
possible.
Multi session CDs include mixed file types
(e.g. MP3 and audio CD) in either succes-
sive or random order on the disc. Audio

Clean the CD with a dry, lint-free cloth.
Wipe the CD a straight line from the
center. Never wipe the CD in a circular

Do not use rubbing alcohol or solvents
to clean CDs.
Do not expose the CDs to cold, heat or
direct sunlight.
Do not write or put labels on CDs.Permissible MP3 CDs
In MP3 mode COMAND can read CD-R and
CD-RW CDs.
Permissible file systems
The permitted file system for COMAND is
ISO9660/Joliet for CD-R and CD-RW.
Multi session CDs
Multi session CDs include mixed file types
(e.g. MP3 and audio CD) in either
successive or random order on the disc. In
MP3 mode, COMAND will integrate audio
CD tracks into the disc’s folder structure.
The CD audio track folder will appear first
followed by folders containing MP3 tracks.
File structure
When creating a MP3 CD, you can organize
MP3 tracks into folders. A folder can also
contain additional folders.
A CD may have a maximum of 255 folders
in total.A maximum of 255 tracks are permissible
per folder.
Mathematically a maximum of 65025
tracks would result. However, this amount
is usually not reached since MP3 requires
approx. 1 MB storage per minute recorded.
Track names and folder names
When creating a MP3 CD, you can assign
names to the MP3 tracks and folders.
COMAND uses these names in MP3 mode
for the corresponding display.
Please note the following when assigning
folder and track names:
Track and folder names must contain
at least 1 character.
Track names may contain up to either
thirty or fifty characters depending on
the CD format. If a name exceeds this
character limit, COMAND will not be
able to display it in full.
Track names must have the extension
“mp3”.

CDs, software and hardware for writing
audio data to CDs vary widely.
Therefore, we cannot guarantee that
COMAND will be able to play every
user-written CD. Problems may also be
encountered during playback of user-
written CDs with a storage capacity of
more than 700 MB.

MP3 CD operation
A period must appear between the
track name and the file extension.
Example of a correct track name:
Track1.mp3
Empty folders or folders containing data
other than MP3 or audio CD tracks will not
be displayed by COMAND.
If MP3 or audio CD files are stored in the
root directory itself, the root directory also
counts as a folder. COMAND will then
display the root directory name as a folder
name.Permissible MP3 formats
COMAND supports the MPEG1
AudioLayer3 format.
Permissible bit and scan rates
Fixed and variable bit rates up to
320 kbps
Scan rates from 24 kHz - 48 kHzThe music tracks that you can create for
play back in MP3 mode are generally
copyright-protected under applicable in-
ternational and national laws.
In many countries, the reproduction of
copyrighted material is not permitted,
even if only for personal use, without the
express prior consent of the copyright

for your country and comply with them.
These restrictions do not apply for exam-

Tips on creating MP3 tracks
i
In everyday speech, this format has
been replaced by the designation
“MP3”.
i
It is recommended to use MP3 tracks
with a bit rate of128 kbps or higher and
with a scan rate of 44.1 kHz or higher.
Lower rates may impair quality. This is
particularly true if the sound function
LOGIC7 Surround has been activated.
