resetting.
Power-on Volume
- Constant: The power-on volume remains the
same as that before the last power-off.
- Adaptive: Whatever the volume is before the
last power-off, the volume of the system is
defaulted to be 15 at the time of power-on
after powering off.
- After restoring factory settings, it defaults to be
“Adaptive”.
Speed Dependent Volume Control
Speed dependent volume control can select off,
low, medium, high, which adjusts the
amplitude of sound under the influence of the
acceleration or deceleration.
- After restoring factory settings, it defaults to be
“Off”.
- The output volume performs automatic
adjustment along with the speed change. The
state table of volume along with speed is as
follows:
Status Volume Change

speed
Low The sound will be changed with the
speed at a low degree
Medium The sound will be changed with the
speed at a medium degree
High The sound will be changed with the
speed at a great degree
