Playback options
General notes
If the Bluetooth®audio device supports the cor-
responding function, the following options are
available:
RNormal Track Sequence: the tracks are
played in the normal order (e.g. track 1, 2, 3
etc.).
Audio data playback is determined by the
order in which the tracks are written to the
data medium. Alphabetical order is the most
common. Once all the tracks in a folder have
been played, the tracks in the next folder are played.
RRandomTrackList: the current track list is
played in random order (e.g. 3, 8, 5 etc.).
RRandom Medium: all tracks on the data
medium are played in random order (e.g.
track 3, 8, 5 etc.).
Playback options are optional functions and
are not, or only partially, supported by Blue-
tooth
®audio devices.
