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 F1 ROOT. All files
contained directly under the root directory are accessed
prior to any root directory folders. However, playlists (Px)
are always accessed before root folders or files.
Empty Directory or Folder
If a root directory or a folder exists somewhere in the
file structure that contains only folders/subfolders and
no compressed files directly beneath them, the player
advances to the next folder in the file structure that
contains compressed audio files. The empty folder does
not display.
No Folder
When the CD contains only compressed files, the files
are located under the root folder. The next and previous
folder function does not function on a CD that was
recorded without folders or playlists. When displaying
the name of the folder the radio displays ROOT.
When the CD contains only playlists and compressed
audio files, but no folders, all files are located under the
root folder. The folder down and the folder up buttons
search playlists (Px) first and then goes to the root
folder. When the radio displays the name of the folder
the radio displays ROOT.
Order of Play
Tracks recorded to the CD-R or CD-RW are played in
the following order:
•
Play begins from the first track in the first playlist
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
folder mode has been chosen as the default display.
The new track name displays.
