Korg Poly800/EX800 Users

Thanks for the help everybody! I guess it could be the battery 
backup. I opened up my Poly 800 to do a filter mod and 
remember seeing the battery. Is it very hard to replace the 
battery? I have only preformed synth surgery once(filter mod) and 
was sucessful.

all three of em. I hate leaky batteries.So I only load them when im 
playing tours. I do have the diagram where to solder to if youd 
like to add the battery back up.
