M3u playlists are not compatible with the
audio player.
MP3i (MP3 interactive) and MP3PRO for-
mats are not compatible with the audio
player.
The player is compatible with VBR (Vari-
able Bit Rate).
When playing back files recorded as VBR
(Variable Bit Rate) files, the play time will
not be correctly displayed if the fastfor-
ward or reverse operations are used.
It is not possible to check folders that do
not include MP3/WMA files.
MP3/WMA files in folders up to 8 levels
deep can be played. However, the start of
playback may be delayed when using
USB memory containing numerous levels
of folders. For this reason, we recommend
creating USB memory with no more than
two levels of folders.
