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
 |
| Rack ears |
 |
| 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.

| Slide back |

| Inside of the M3r |
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.
 |
| Slide in and push down to complete |
|
 |
| simple pressure removes the battery |
|
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.

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.
Glad to have helped..
Thanks very much! I just replaced a battery too on my trusty old M3R. Works like a champ now!
Hello -
My name is Greg and I have a question:
Can you still run a Korg M3R without a battery?
I realize that memory will be lost everytime you turn off/on, but will it still load factory sounds?
Thanks,
Greg
Hello! My name is Marco Antonio Bouquard, musician from Brazil. I was already desperate trying to solve this problem with the M3R battery and your blog helped me a lot! Thanks for the force!

I just replaced the internal battery using your pictures. Thanks!
Got the Battery Low-warning, changed the battery but nothing changed, same warning persists and presets not being saved. Any ideas what could be be problem?
marjavanukas The 3 for a $1 batteries at the dollar store are a waste of time for this. They have long shelf life and MAY work for 1 month IF YOU ARE LUCKY. If you go to the trouble of pulling this apart, you better put a decent battery in.
