Hi Toril,
make sure that all Pedals are properly connected BEFORE powering up the keyboard. And do NOT press any Pedal until the keyboard is ready to play. (Otherwise the Pedal will work "reversed".)
Use allways the same Pedal socket for the Sustain Pedal (usually Pedal socket #1).
The Polarity of the Pedal is automatically detected on startup. (This is the reason that you must not press the Pedal at this time.}
If the Pedal works "reversed" nevertheless, press Direct Access, then press the Pedal (this opens the Assignable display) , and then manually change the Polarity, so that the Pedal works correctly.
Note: CLOSE the Assignable display correctly (by pressing the Exit button or touching the X icon). Only when doing so, the Polarity setting is correctly saved (in the so called "System Setup") So, do not leave the Assignable display open in the background.
Best regards,
Chris
