repeatedly until a display like the one shown
opposite appears. Then use the button to

With the feature activated, the audio unit
automatically detects sound distortion and
reduces the unit's volume level until the
distortion has been eliminated. This means
that when the volume control is adjusted, with
the CLIP function switched on, there may not
be an increase in sound.
