SCV:
Your system has a feature called
Speed-Compensated-Volume (SCV). With SCV,
your audio system adjusts automatically to make
up for road and wind noise as you drive. Set the
volume at
the
desired level. Move the control ring
behind the upper knob clockwise to adjust the SCV.
Then,
as
you drive, SCV automatically increases the
volume, as necessary, to overcome noise at any
particular speed. The volume level should always
sound the same to you as you drive. If you don't
want to use SCV, turn the control all the way down.
Each detent on the control ring allows for more
volume compensation at a faster rate of speed.
