Terry is good at answering emails, I'll give him that.
I actually just got an email back from him and he said the same thing. I was messing with it and pressing and holding the button a bunch trying to figure it out. I hope that didn't mess anything up! haha. However, i'm sure once its unplugged, it resets itself. He said to just keep it plugged in and it is set for auto clear, so that should do the trick.
