The date changed on my dive computer to the year 20141, see photo. Click on photo for some more details. Aeris A300 CS Strange date by lee_elston posted Jan 6, 2017 at 10:49 AM Any reasonable ideas why?

I was teaching in the pool with my Aeris A300CS. The battery was low, but I started the dive with it anyway. I turned it on when I was in the water, it came on, stayed on for a few seconds and then shut down. It came back on briefly a few minutes later and ever since, I get the "error last dive"...
