that was recorded using no file folders can be played. If
a CD-R or CD-RW contains more than the maximum

Root Directory
The root directory of the CD-R or CD-RW is treated as
a folder. If the root directory has compressed audio
files, the directory is displayed as the CD label. All

Order of Play
Tracks recorded to the CD-R or CD-RW are played in

and continues sequentially through all tracks in
each playlist. When the last track of the last playlist
has played, play continues from the first track of
the first playlist.
•
Play begins from the first track in the first folder and
continues sequentially through all tracks in each
folder. When the last track of the last folder
has played, play continues from the first track of the
first folder.
When play enters a new folder, the display does not
automatically show the new folder name unless
the folder mode has been chosen as the default display.
The new track name displays.
