Scanning Compressed
Audio Disc
Scanning a compressed audio disc
categorizes and allows sorting of
songs by folder artist or album.
• Select center folder/artist/album
button to initiate scanning
mode. The radio plays and a
progress bar displays.
• Background scanning occurs with
the radio on and the compressed
audio disc inserted but not
being played.
• Only the first 200 songs appears
in the compressed audio music
navigator.
• Scanning time varies depending
on the number of files and
folders on the disc.
Root Directory
The root directory is treated as a
folder. If the root directory has
compressed audio files, the directory
is displayed as ROOT. All files
contained directly under the root
directory is accessed prior to any
root directory folders.
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 and
the empty folder is displayed or
numbered.
No Folder
When the disc contains only
compressed files, the files are
located under the root folder.
The next and previous folder
functions have no function on a disc
that was recorded without folders.
When displaying the name of
the folder the radio displays ROOT.
Order of Play
Tracks are played in the following
order:
• The radio does not support
playlist files.
• Order of play differs depending
if the compressed audio disc is
fully scanned or unscanned.
See “Scanning Compressed
Audio Disc” previously in
this section.
• When playing an unscanned disc,
the next and previous screen
buttons may be required to switch
away from the current folder
when quickly seeking rather than
allowing the last song of a folder
to play to completion.
