Yamaha MU80 battery replacement

I have the Yamaha MU 80 desk top style or half rack module. It’s reading low battery. It’s a soldered in the circuit board kind. Can anyone help?

Hello,
The original battery is a CR2450-F2MX1H which you certainly don’t find anymore
You can use a VARTA Microbattery CR 2450 PCB3.
it’s very easy to replace if you have the right tools
Check out the service manuals to properly opening and dismounting the unit

I’ve done it and took me less than 30min to do the whole thing.

You guys are a day late and a dollar short! I repaired this months ago with a standard CR2032 pancake battery and battery holder. I can send photo of the mod? If you want to see? It’s working fine now. No more low battery on screen. All functions are working as normal.
