Hi everybody,

I have a little problem with my Kn2600. When I shut it down for a few hours and power it up the next morning, it has lost all of my original sound memories and resetted back the factory presets. I have to reload them every time I use it. Is that normal with this machine (I don't have that issue with my Kn7000)or is this a matter a low backup battery inside the machine?
Thanks
