Need some help here

[Ted Nesbitt]

I have a Yamaha RX120 drum machine in my music room, have it for years. Great machine, but recently the little screen is giving me a message saying "Change battery" I have no idea where the battery is, or what type of battery is required. I opened it up by removing 6 little screws, but Im still none the wiser. Anyone out there got any ideas? Dave Kirk or Basil would be knowledgeable on electronics. Appreciate any help.

Hi Ted,
There are several videos on yootoob showing what to do, but none showing for the the RX120.
Here is a video on how to replace the battery on the RX7, sorry it's not the same unit, but will give you an idea what you're looking for.
After the 'back up memory battery' is removed, the unit will need resetting when the new battery is fitted. Hope you can get it sorted.
