So I've had this thing for about 5 years now and just recently I've gotten a 'battery low! please replace' warning when I start it up, I assume it's referring to the memory battery.

The warning doesn't always happen though, sometimes it'll start up normal.

Just wondering before it actually does run out, how do I replace it?
The manual says to send it in to Roland, but I've read of a few people who've changed it themselves, no instructions though.

I guess I'm just asking because I have no idea where the battery actually is, do I screw off the whole back plate? I believe it's a CR2032.
