3.2. Disc sequential random play 
Fi
rst press the Random button. Then select the MP3 disc: press the correct Disc number 
button on the remote control unit (depending on which tray the MP3 disc is in). 
Press play. The player will now randomly select and play tracks of the selected MP3 disc. 
Disc sequential random play will end when the playing stops (= all tracks have been played).  
It’s possible to select up to five discs. The same disc can be selected more than once. 
3.3. Cancelling Random play 
To cancel Random play, you press the Random button once more. The player will then 
proceed from the track that is currently playing and will play continuously until the last track 
of the disc has ended. After that point, playing will stop.  
Another way to cancel Random play is to press the Open/close button. 
The 1 track and 1 disc repeat modes can’t be set during Disc sequential random play. 
4. More information about MP3 files 
When you write MP3 files on a CD-R/RW disc, be sure to use a writing program with which 
you can record in “ISO9660” format (this is not possible with all writing programs). Set the 
writing program’s format to “ISO9660 level 1” or “ISO9660 level 2”, because MP3 files that 
are written in other formats may not play properly. 
It’s possible that the writing program changes the positions of the folders and files while 
writing MP3 files on the CD-R/RW disc. Hence it’s possible that the files aren’t played in the 
order you expect.  
The sound quality of your MP3 disc depends on its bit rate: the higher the bit rate, the better 
the sound quality. When you want to play your MP3 files with the MCD15, it’s best to use 
MP3 files written with a bit rate of 128 kbps or greater.  
Be sure to give you MP3 files the following extension: “MP3”. Files with another extension or 
files with no extension at all can’t be played. When using a Macintosh computer, it’s possible 
to play MP3 files, when adding the extension “MP3” after the file name. This name may 
consist of a maximum of 8 Roman capital letters and/or numerals when recording them on 
CD-R/RW discs.
