I got my 733 a few weeks ago and love it! Little cumbersome to use but once you get the manual next to you it is easy. So I used it for the first "real" bbq yesterday. After bout an hour smoking I look down at it & it says 250 degrees but my alarms were set to 215-235... What gives? No sounds, no blinking, no nothing? Anyone run into this issue before? I tried resyncing, turning both units off and resetting the temps, I don't get it?
