Basic information on use ⇒ page 8
Requirements for media sources and audio files
Factory-fitted CD players conform to safety class 1 according toDIN IEC 76 (CO) 6/ VDE 0837.
The unit only accepts 12-cm standard CDs.
Media sourceRequirements for playing in the unit Audio CDs (up to 80 min).– CD Digital Audio specification . CD-ROM, CD-R, CD-RW upto max. 700 MB (megabyte)according to ISO 9660 or onthe Joliet data system.
MP3 files (.mp3) with bitrates of between48 and 320 kbit/s or with variable bitrates– Playlists in formats PLS and M3U– Playlists no larger than 20 KB and con-taining no more than 250 links.– Max. 32 playlists on a data medium.– File names no longer than 64 characters.– Folder structures with a maximum of tenlevels.– Max.120 folders and max. 500 files on adata medium.
AUX: External audio source.– A 3.5 mm jack plug can be used for audiooutput ⇒ page 23.
Restrictions and notes
Contamination, exposure to high temperatures and mechanical damagemay render a data medium unusable. Observe the manufacturer's instruc-tions on the data medium.
Variations in the quality of data media produced by different manufacturersmay lead to problems during playback.
Observe copyright laws!
CDs recorded in UDF or Direct CD format cannot be played. Under WindowsVista® ensure that the correct format is selected.
The unit may be unable to read individual tracks or the entire data mediumdue to the data medium configuration or the devices and programs used forrecording. Compatibility with all encoding/recording software, recording de-vices and recording media cannot be guaranteed. Information can be foundon the internet regarding the best ways to create audio files and data media(compression rate, ID3 tag etc.).
Page 19 of 35

18Audio modeDue to the larger quantity of data, the unit takes longer to read a data medi-um containing compressed audio files (MP3) than a “normal” audio CD.Complex folder structures can also slow down the reading of a data medi-um.
Playlists only determine a certain playing order. There are no files stored ina playlist. The unit will not play a playlist if the files are not on the data me-dium at the locations referred to by the playlist (relative file paths).
Playing order of files and folders
Fig. 13
Example of anMP3 CD structure.
Audio files on data media are often organised by means of folders andplaylists 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. 13 shows a typical MP3 CD that contains tracks ,folders and subfolders.
Accordingly, the tracks and folders on this CD are played and displayed inthe following order:
Tracks
1
and
2
in the root directory (ROOT) of the CD
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).
Track
6
in the first subfolder F1.1.1 of the subfolder F1.1 (display: 03).
Track
7
in the second subfolder F1.2 of the folder F1 (display: 04).
Tracks
8
and
9
in the second folder F2 (display: 05).
With regard to the playing order, playlists are treated like folders.
