on the USB device were originally encoded with
incompatible software, those files may produce
noise or may malfunction.

system can recognize is:
– 256* folders (including the root folder)
– 999 files

– 8 folder levels (in the tree structure of files)
* This includes folders that have no playable
audio files and empty folders. The number of
folders that the system can recognize may be
less than actual number of folders, depending
on the folder structure.
• The system does not necessarily support all the
functions provided in a connected USB device.
• Folders that have no audio files are not
recognized.
• The audio formats that you can listen to with this
system are as follows:

may produce noise or may malfunction.
** Files with DRM (Digital Rights Management)
copyright protection or files downloaded from
an online music store cannot be played on this
