Portable Keyboards and Digital Pianos: Sustain Pedal

Polarity Reversed.

If a sustain pedal plugged into a Yamaha keyboard is producing the opposite effect - sustaining when the pedal

is not depressed, and not sustaining when it is depressed - it's usually because (a) the pedal was plugged in

while the keyboard was turned on, or (b) the pedal was depressed while the unit was powering on. This tricks

the keyboard into thinking the default state of the pedal is depressed, resulting in a reverse polarity or reverse

function. There's an easy way to remedy this:

1) With the unit turned on and the sustain pedal plugged in, depress and hold the sustain pedal while you

power the unit off.

2) Release the sustain pedal once the unit has been turned off.

3) Turn the unit back on.

That usually fixes reversal of polarity, and if you're using a non-Yamaha sustain pedal, those sometimes have

polarity switches that may solve the problem without need for the steps above.
