So I've used my Dreamcast quite a few times and every time I start it it asks me to set the date and time. Is this something to do with batteries in the system? I think it's the saturn that has cr2032s inside, is it the same case with the DC? I just want it to save the settings. And also for curiousity what is the attachment on the bottom right side that says something about a fire hazard when you take it out?

Thanks,

Chris
