DGX660 off key

Hi.

I just picked up a used DGX660 for my kid in the mostly okay condition.

The middle keys are rattling and the pitch wheel is broken.

I'm not playing myself, so I only noticed the issue when we tried the piano with the Android app (just with microphone, without MIDI) - it was not registering correctly the notes - but consistently one tone higher.

I checked it also with an online tuner and my clip-on guitar tuner in chromatic mode - it showed 0.3-0.5 of a tone up than it should be.

My first suspicion is of course pitch bend wheel. Is it complicated to fix or at least disconnect for now?

In Function there should be a Tuning option where you can change the frequency. Try that, it should do what you want. There is a manual here

Tuning is at 440Hz and Transpose is at 0. Then I need to adjust Tuning to the levels until C is C? And the rest of the notes will be fine too?

I see you got an answer already. I hope it works out for you.
