— The media sources do not support the Win-
dows Media Audio 9 Voice format.
— For compressing MP3 files, Audi recom-
mends a bit rate of at least 160 kbit/s. The
display showing the remaining play time
may differ for audio files with variable bit
rate.
— Special characters (such as those in ID3 tag
information) may display differently or may

not always display, depending on the sys-
tem language.
— The manufacturer of the storage device can
provide information about its “USB Device
Subclass”.
— Some MTP player functions are not support-
ed, such as rating music tracks and video
playback.
