Quoted from stangbat:
Time and date not set error two times in the last two days. This was after replacing the battery a couple of months ago.
I have this issue on mine and it's only a few weeks old. I had to move it to a dedicated outlet instead of a switched one. Used to have the pinballs on a switched outlet, so you walk in, flip the switch all the games come on.
Any idea if this is a battery issue or something else?
