I've used my ET-733 twice now. The first time I plugged in the probes I got a HHH code on the receiver display screen when I had it on its holder in the smoker. Since I was smoking ribs and didn't need the meat probe I removed it from the smoker and unplugged it. I'd only had it in there as a test anyway. Yesterday, I smoked a brisket and again the receiver meat probe temp showed HHH or it was blank. I unplugged and plugged it in. I shut off both units, turned them on and re-synced them and suddenly, lo and behold, I was getting the meat temp and it remained working for the rest of the smoke until I turned the units off. Both units worked perfectly and it was great monitoring the smoke while sitting on the couch watching TV. Anyone else had this happen? If so, did it just happen during the first use or has it been recurring?
