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.

Legend: weather fronts
Weather frontExplanation
Cold front
(blue line with blue trian-
gles)If a cold front moves in, the weather remains changeable and there
are often rain showers and thunderstorms. The air temperature
decreases.
Warm front
(red line with red semi-cir-
cles)A warm front may cause more prolonged steady rain, more cloud
cover and a slow rise in temperature.
Stationary front
(red and blue line with red
semi-circles and blue trian-
gles)The weather front moves minimally. The weather remains change-
able in this area.
Occlusion
(purple line with purple
semi-circles and triangles)An occlusion arises when the faster cold front catches up and joins
the warm front ahead of it. The weather remains changeable and
rainy within an occlusion.
