Thank you for replying - I googled which keys these are & think you mean the first & last key on the keyboard which are A & C...
Nothing happens - have tried holding down & turning on then releasing & turning then pressing - Piano 1 still flashes & no sound
Look forward to next step...
Before we through it away, can I just check the keys are the first & last keys on the keyboard - the A & C
But the Keyboard only has 52?
Just trying to save the instruments life before it's dumped!
