other interference can cause the unit to malfunction. If this
occurs, turn the power off and, after waiting for about one
minute, restart operation.
MP3 Playback Order
MP3 files on a CD or a USB flash drive can be stored in folders in the
same way that files are managed on a computer. Moreover, multiple
folders can be contained inside another folder.
Here is an example of the file and folder structure of an MP3
disc or a USB flash drive, showing the order of the folders
(001 “ROOT” to 005) and the playback order of the files
(
