Pedal Adjust

Press “Pedal Adjust” and then slide the “Start/Stop Test” button to the right to start the adjustment.

Turn OFF the “Thump Reduction” by sliding the button to the left.

The sustain pedal solenoid and the sustain dampers should start to cycle ON and OFF.

This procedure is not necessary on systems, usually uprights, that do not have a sustain pedal solenoid.

Press the “-” buttons to set the “Initial Drive” and “Hold” values to zero.

Watch the sustain dampers and press the “Initial Drive’s” “+” button until the dampers move off the

strings.

Then, press the “Hold’s” “+” button until the dampers lift up and hold off of the strings.

Turn ON the “Thump Reduction” by sliding the button to the right. Thump reduction will pulse the

pedal solenoid as it’s release to break it’s fall and reduce noise.

Adjust the release up and down until the solenoid drops quietly.

Stop the adjustment by sliding the “Start/Stop Test” button to the left.
