Sorry I'm kind of new at this but my pansat 3000 is acting weird. With Bev it keeps on changing keys on its own every 10 minutes. I'll change the keys, save it, and then it'll work for about 10 minutes then it stops working. I'll look back on the keys and they're back to what they were before I changed them. It's getting really annoying changing them over and over again (especially because I'm just changing it back to the same keys) and I don't understand why it's doing this on its own. Please help
