Only use MP3 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
noticeable deterioration in quality. This is
especially the case if you have activated a
surround sound function.
Notes on copyright
MP3 or WMA tracks that you create yourself
or play back are generally subject to copy-
right protection in accordance with the appli-
cable international and national regulations.
In many countries, reproductions, even for
private use, are not permitted without the
prior consent of the 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 about CDs/DVDs
i
Discs with copy protection are not com-
patible with the audio CD standard.
Audio 50 APS may not be able to play them.
There may be playback problems when
playing copied discs. There is a wide range
of data carriers, writing software and
CD/DVD writers 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.
! Do not affix stickers or labels to the discs,
as they could peel off and damage the disc
drive.
The CD drive is designed for data carriers
that conform to EN 60908. For this reason,
you can 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 they can damage the CD
drive.
Do not use discs with a diameter of 8 cm,
even with an adapter. Only use round discs
with a diameter of 12 cm.
Notes about handling CDs/DVDs
Only hold discs by the edge.
R
Handle discs carefully to prevent playback
R
problems.
Avoid getting scratches, fingerprints and
R
dust on discs.
Clean discs from time to time with a com-
R
mercially available cleaning cloth. When
cleaning CDs, you should wipe in straight
lines from the centre outwards rather than
in a circular motion.
Only use a pen specifically made for label-
R
ling discs.
