106 Control systemsCOMAND audio CD/audio DVD/MP3If you own these rights yourself, e.g. for 
your own compositions and recordings, or 
the copyright holder has granted you per-
mission, these restrictions do not apply.Notes about audio DVD operation
COMAND can playback commercially 
available, prerecorded audio DVDs that 
bear the following label. You will usually 
find the label on the DVD booklet, the inlay, 
or the DVD itself.
Data on audio DVDs are stored either in 
uncompressed format or in lossless com-
pressed format. The sound quality on au-
dio DVDs is therefore better than on 
recordable DVDs that contain MP3 data 
because the MP3 format uses a lossy type 
of compression.You cannot delete data from or record 
additional data to commercially available, 
prerecorded audio DVDs.
Please note the following information 
about CDs/DVDs and pay special atten-
tion to the notes on copied and/or 
self-written CDs/DVDs.
Notes about CDs / DVDs
i
Audio DVDs differ from recordable DVD-R, 
DVD+R, DVD-RW and DVD+RW discs.
i
COMAND cannot playback video DVDs.
i
Audio CDs with copy protection are not 
compatible with the CD audio standard and 
therefore may not be able to be played by 
COMAND.
There may be playback problems when playing 
copied discs.
There is a large variety of discs, disc-writing soft-
ware and writers available. This variety means 
that there is no guarantee that the system will be 
able to play discs that you have written/copied 
yourself.
There may be playback problems if you use CD-R 
or CD-RW type discs you have copied yourself 
with a storage capacity of more than 700 MB. 
These CDs are not compatible with currently ap-
plicable standards.
!
Do not affix stickers or labels to the discs. 
These could peel away and damage COMAND.
COMAND is designed to hold discs which com-
ply with the IEC 60908 standard. You can there-
fore 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 cannot be ejected and 
can damage COMAND.
Do not use discs with an 8-cm diameter, even if 
they have an adapter.
Only use round discs with a 12-cm diameter.
