Notes on copyright
The music tracks that you create and play
back in the MP3 or WMA format are generally
subject to copyright protection in accordance
with the applicable international and national
regulations.
In many countries, reproductions are not
permitted without the prior consent of the
copyright holder, not even for private use.
Make sure that you know 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 the
copyright holder has granted you permission,
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.
i Audio DVDs differ from recordable DVD-
R and DVD-RW discs.
Data on audio DVDs are stored either in
uncompressed format or in lossless
compressed format. The sound quality on
audio 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 attention to the
notes on copied and/or self-written CDs/
DVDs.
Notes about CDs/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
software 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 applicable
standards.
