Playing MP3-CD Music Files
When you load an MP3-CD, folders that contain MP3
files are displayed alphabetically.
Numbered folders are displayed sequentially. Folders
that contain no tracks do not appear.
After the table of contents is read the first track displays
and begins to play.

This indicates there is no CD in the player, the CD is
upside-down, or the CD cannot be read. Other controls
are deactivated. The message displays until the player
door is opened or the player is automatically or manually
turned off.
