Automatic Level Control (ALC)

The automatic level control is a feature 
that automatically adjusts audio volume 
and sound quality according to the vehicle 
speed.
The volume increases in accordance with 
the increase in vehicle speed, and 
decreases as vehicle speed decreases.

The following seven modes are available. 
Select the desired mode according to use.

NOTE

About 5 seconds after selecting any 
mode, the volume function will be 
automatically selected. To reset bass, 
mid-range, treble and balance, press 
the audio control dial for 2 seconds. 
The unit will beep and "CLEAR" will
