amin

ation, exposure to high tempera-
tures and mechanical damage may render a
data medium unusable. Observe the manu-
facturer's instructions on the data medium.
Variations in the quality of data media pro-
duced by different manufacturers may lead to
problems during playback.
Please observe copyright laws. CDs recorded in UDF or Direct CD format can-
not be pl

ayed. Under Windows Vista ®
ensure
that the correct format is selected.
The unit may be unable to read individual
tracks or the entire data medium due to the
data medium configuration or the devices
and programs used for recording. Compatibil-
ity with all encoding/recording software, re-
cording devices and recording media cannot
be guaranteed. Information can be found on
the internet regarding the best ways to create
audio files and data media (compression
rate, ID3 tag etc.).
Due to the larger quantity of data, the unit
takes longer to read a data medium contain-
ing compressed audio files (MP3) than a
“normal” audio CD. Complex folder struc-
tures can also slow down the reading of a da-
ta medium.
Playlists only determine a certain playing or-
der. There are no files stored in a playlist. The
unit will not play a playlist if the files are not
stored on the data medium at the locations
referred to by the playlist (relative file paths).
