Comfort controls
Random playback for all folders on a disc (MP3 CDs only)
Select the RDM mode, and the RDM indicator (13) will come
on. Tracks from all the folders on the currently selected disc
will be played in a random sequence.
NOTE
In the all discs random mode, if an MP3 CD has been
loaded in the autochanger, the autochanger will skip over
it to the next music CD.
With a disc that contains both CD-DA and MP3 files, the
random mode causes only files of the same format (CD-
DA only or MP3 files only) to be played in a random
sequence.
