One of the batteries I replaced in my O2 lasted only a few weeks. I suspect
that it had been on a vendor's shelf for too long. I was having the same
symptoms you are reporting. A new battery from a different vendor fixed the

Good luck,

Some weeks ago, I sent a note regarding several problems I'm having with my
Orion II. Perhaps I can ask this time about one specific issue:

Whenever I power-on my O2, it does a Master Reset.
(And, of course, loses all USER1 and USER2 settings.)

The caps on the A9 board were replaced a couple of years ago.
I replaced both batteries a few weeks ago.
I've tried both firmware 3.033xa and 3.033xe.
And did the necessary Master Resets and RAM Clears.
I've removed all external interfaces (MicroKeyer).

Still happens.

Anyone have any clue?

(I'm thinking that if I get this issue solved, maybe the other issues go
away too.)

Thanks for any suggestions.
