KORG SP170

[#$Garry$#]

Hello!
I need someone's help on how can I fix the problem with my KORG SP170...
I have it since long ago and during last years it wasn't utilized... but stored properly, in a dry place...
Now I tried to use it again and it turned out, that I can't switch the regimes (Piano1, Piano2 etc.) by certain combination of keys...
What is the reason?
Looking forward to get an advise....

Try backing up your settings and doing a system reset.
