2) Confirmation
This confirmation mode is to make sure that the key shutter strokes are within the adjustment range.
Select one key.
That key will sound if its AD value is either 0% or over 98% of the maximum value.
As a guide to finding that the key is positioned correctly, lift up the key and set the open value to the maximum.
The key position is correct if the key does not sound at either the rest or the end value.
Note: If the sound keeps sounding during adjustment, restart by pressing the damper pedal.
