Got my first VMU and cleaned it up nicely. Placed 2 new CR2023 (3V) batteries into it. Set the time, checked out the previous owners saves and put it to Sleep on the desk. Came back the next day and it is flashing the bottom nav with a black screen and the set year over and over. If I remove the batteries and put them back in, it says to replace the batteries.
I know the battery life is awful on these things, but something seems wrong if its under 24 hours without even being used. Could something be shorting out?
