Korg M3r Battery Replacement

Today I had to replace the battery in my Korg M3r. All the patches had been wiped and all I could play was the eponymous 90's house piano. Luckily, it's an easy fix and I thought i'd share it with you nice people. First thing you need is a new battery - a CR2032 (flat disc type) which I purchased from Maplin (£3.99) - I had to get two as my PC needed a new battery too ( an odd coincidence?).
Anyway, pictures are easier than words so I'll let the camera tell the story...

First, remove your M3r from the rack and unplug it - no need to kill yourself over a battery.

1. Remove all the screws either side of the synth

Repeat on other side






















2. Now remove the two screws at the back. Then the three on the case top.

Case top - three screws
Case Rear - two screws





















3. Now you can slide the case back to reveal the innards.

The battery is in the top right corner and is a doddle to change - it simple pops out and you can slip a new one in - no screws required.

Now, resetting the internal sounds. Click the "Edit" button. Then the "Global" Button. Then press "Combi" five times to get to "5A Load". Click "Prog"  Three times to get to page "5D Preset Data".
Press "Yes" to load the default presets. Hopefully you would have backed your precious home made patches into a librarian or sys-ex file so that you can reload those instead.

Hit "Yes" and...
..Success!




Hope that was of help to any other M3r owners, or just of interest to anyone else.

Thanks for posting this. I also own one of these relics of the past, bought it new in 1991. It's still a great little box, even now in 2015, esp. for recording. I was stuck on how to load the factory sounds, as I knew they were burned in ROM in the unit. Thanks again for the info.
