Random playback for all folders on a disc (MP3 CDs only)
Select the RDM mode, and the RDM indicator (12) will come
on. Tracks from all the folders on the disc will be played in a
random sequence.
NOTE
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.
