If I had to guess (and assuming everything is working correctly) I would guess that you turned them on in the wrong order. You need to turn on the TX first (the one with the probes) and then the receiver and you should not get the dashes.
Hope that helped and sorry for the multiple posting
Ok, after its set what do I do to put it into the monitor temperature mode? Im talking about the reciever. All I see is 3 flashing dashes on both the meat and smoker temp display. Sorry to be such a pain in the arse.
Ok I got it now. All I had to do was turn on the reciever first, so Im a jackass . Thanks for all the responses and again sorry for being a pita. Im a happy smoker now and cant wait till the weakend to give it test run.
