Vintage Synth Repair

It isn't a CR2032. From memory, it's the less common CR2450.

It is socketed and I can confirm it is possible to change it while the unit is switched on - just be careful not to touch anything other than the battery. I did it without any problems. The toughest part is the insane number of screws you have to undo to take the bottom off.

I've heard of problems where people have swapped out the battery with the unit powered down. If you do that you will have to do a factory reset and a midi dump to get your presets back. I believe without the factory reset you'll have problems with things like the ribbon controller. I'm not sure though how you do the reset though. I swapped the battery 'live' to avoid such problems.
