Kawai K4 internal battery?

[kasperhb]

Hi
I have a Kawai K4 but I can't turn it on. I think it is the internal battery?

I can probably shift the battery but what about the stored sounds then?
Do I need to load them again in a way? Where to get it?
best Kasper

Kawai k4 battery replacement while keeping the factory sounds? - Gearslutz

Hi there, Just picked up this unit, I'm worried about losing the factory presets if the internal battery goes out. Is it possible to replace the battery 'hot' i.e. plugged in so that the memory stays powered during a change over? Would rather do
