Variations in the quality of data media produced by different manufacturers
may lead to problems during playback.
Please observe copyright laws.
CDs recorded in UDF or Direct CD format cannot be played. 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. Information about the best ways to create audio files and data
media (compression rate, ID3 tag etc.) can be found on the Internet.
Due to the larger quantity of data, it takes longer to read a data medium
containing compressed audio files (MP3, WMA etc.) than a “normal” audio
CD. Complex folder structures can also slow down the reading of a data me-
dium.
Playlists only determine a certain playing order. 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). Playing order of files and folders

numeric order. 
