Years ago, i bought a GEM rp150 digital piano to learn play with a piano.
For years, the piano played very well.
A few weeks ago, the piano didn't start up and i contacted my music store to fix the problem.
They told me that the battery is possible leaking and after checking, it was.
I replaced the battery but to start up the piano, i have to set it to factory settings.
The musicstore came up with some guide to reset but is was for an other piano and useless for me.
Does anyone here know how to set this piano to factory settings so i can play my music again?
