Help - got a warning (in German) about battery safety. Has anyone replaced the lithium battery in the MM-9 or have instructions?

Thank you.

Hi

There is a bright yellow battery on the main board that needs to be replaced. 

you can buy them from RS components for a couple of pounds. The trouble is that you have to replace the battery whilst it is powered up. if you do it when the system is powered down you loose the memory and end up having to replace the main board.
