FIN. That’s good. Because the only function of that clock is time of day. And the only thing that should cause it to reset is a loss of battery power. And even then, I’ve had my battery out overnight and it kept time. I don’t use 24hr format so can’t vouch for that. As a long shot, if you wanted, next time you start up and while you’re waiting to warm up, cycle through every one of your preference settings, change them or adjust them and change them back, in order to rewrite all those settings back into memory. If the problem continues I’d focus on exactly when it resets. That is, when they key is turned on, when the start button is pushed, etc. What happens to cause it. Good luck with it.
