Restrictions and notes
Contamination, exposure to high temperatures and mechanical damage can
render a data medium unusable. Please observe the manufacturer's instruc-
tions.
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. Compatibility with all encoding/recording software, recording de-
vices and recording media cannot be guaranteed. Incompatible USB devi-
ces can make noise, interrupt playback or not playback at all. 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 for audio data CDs
Fig. 14 Example of an MP3 CD structure.
Audio files on data media are often sorted by folders and playlists
to
determine a certain playing order.
Tracks, folders and playlists on a data medium are sorted by name in alpha-
betic or numeric order.
Subfolders are treated like folders and numbered in accordance with the se-
quence on the CD.
The illustration ⇒ Fig. 14 shows a typical MP3 CD that contains tracks
,
folders and subfolders.
Accordingly, the tracks and folders on this CD are played and displayed in
the following order: Tracks 1
and 2 in the root directory
of the CD (display: ROOT).
Tracks 3 and 4 in the first folder F1 in the root directory of the CD
(display: 01).
Track 5
in the first subfolder F1.1 of the folder
F1 (display: 02).
