card or USB flash drive that contains audio files into the unit, that
the unit is on, and that the current source is set appropriately.
(see “Selecting the playback source” on page 22)

This display of this unit can only show half-width (normal)
alphabet letters and numbers (single-byte). If a file name
uses Japanese, Chinese or other full-width (double-byte)
characters, playback is possible but those characters will be
replaced with * on the display.

MP3 files are recognized by the “.mp3” extension. Always add
the “.mp3” extension to file names. This unit cannot play MP3
files without the “.mp3” extension. Furthermore, this unit can-
not play files that have the “.mp3” extension if they are not in
the MP3 data format.
i
WAV files are recognized by the “.wav” extension. Always add
the “.wav” extension to file names. This unit cannot play WAV
files without the “.wav” extension. Furthermore, this unit can-
not play files that have the “.wav” extension if they are not in
the WAV data format.

Media with more than 300 files or 50 folders might not play
properly.
i
Depending on the condition of the disc, playback might skip
or not be possible.
Tracks and folders on SD cards and
USB flash drives
This unit handles audio files on SD cards and USB flash drives as
“tracks”.
Some data CDs, SD cards and USB flash drives store files in fold-
ers in the same way that ordinary computer files are handled.
Some also store multiple folders within a single folder, creating a
multi-level structure.
This unit assigns track numbers to audio files for management.
Track numbers are assigned in the following order.
1.
Playable files in each folder are sorted in Unicode order.
Folders, including empty folders and folders that do not
contain playable files, are sorted in Unicode order.
2.
If the root folder contains playable files, those files are as-
signed numbers first.
3.
After all playable files in the root folder are assigned num-
bers, if there are lower-level folders with playable files in
them, those files are assigned numbers
4.
If there are more folders at an even lower level with play-
able files in them, those files are assigned numbers If there
are no folders in the lower level, the unit searches for folders
on the same level, and then assigns numbers to the files in
those folders.
During ordinary playback of SD cards and USB flash drives, tracks
are played in numerical order in the same way as audio CDs.
