Sustain Pedal or Foot Switch is not functioning properly on an S80

The 'Sustain' and 'Foot Switch' jacks on the rear panel of the S80 are made to be used with a Yamaha FC-4 Sustain Pedal or FC-5 Foot Switch.

Due to the fact that some manufacturer's sustain pedals and/or foot switches are configured differently than the Yamaha FC-4 and FC-5, the sustain (or some other parameter) may work backwards, or not at all.

NOTE: The 'Sustain' jack is used for sustain only, however the function of the 'Foot Switch' jack is programmable.
