I’ve been seeing such weird behavior for a few weeks now : my dear old PO-Rhythm switches itself off when I try to put master volume above 6 !
I run it on eneloop rechargeable battteries, maybe they don’t give enough juice, I don’t know.
But it never occurred in the past year, so I’m a bit afraid something is wrong with my little beast.
Has anyone seen this already ?
That is def a battery issue. Same thing happens to me when raising volumes. Fresh batteries = all good.
Thx, it does bring me hope 
I love this little noise maker…
Mine was doing this last night, I thought “Oh no I’ve overloaded it!” but a battery change and all is good.
How long do batteries last in general?
I got two weeks from my first set playing 1-3 hours a night.

Fresh batteries last more than 3 hours of playing, I can assure you.
I already played with a friend for 5 hours straight, me on the Volca Bass and him on the PO-12, and all the acid we played couldn’t empty the batteries
They were not rechargeable though. I’d go for such batteries, brand new ones, to avoid any surprise.
