OK, I have used the ET-733 twice now and been frustrated by it each time. It took me forever to get it set up before use. Each time I was smoking pork butt in the 22.5" Weber kettle. FWIW, I used the snake of charcoal briquettes around the perimeter of the grate with wood chunks for smoke flavor about a third of the way around from the start and placed a drip pan under the meat. I hung the #2 probe under the meat at the center of the grill - not over hot coals - to read the "barbecue" or smoker temp and placed the #1 probe in the meat. I turned on the receiver and then the transmitter and sync'd them without any problems, then it hit the fan.
I struggled to get the receiver probe 1 in the correct mode for pork. I bet I tried 15 times carefully following the example instructions in the sheet that came with the thermo. I was finally able to get it to say FOOD and PORK but was unable to change the HI temp limit. Its default was 160. I couldn't change it. Probe 2 HI and LO settings were at a default of 200 low and 250 high; so that worked OK because the WK came up to 200 pretty quickly. I was never able to change the SET HI temp for probe 1. Because I was °taking the smoke to an IT of 200° the alarm beep started at 160° (the default setting I couldn't change) so I turned the receiver off. As I posted in another thread, I had to finish this butt in the kitchen oven because I ran out of charcoal; so I could keep an eye on the Probe 1 temp and took it out at 201°. All in all I found this a very unsatisfactory experience.
First, the steps to setting it up should be prompts,for choices and should not require the user to remember the key pressing sequences. Second, the term "Barbecue" should be changed to HEAT or some other term. Where I come from, 'barbecue' means food - not just food but Holy Manna from Above. Mavericks use of that terminology is confusing to those of use who think of something to eat rather than the temperature of the cooking environment.
In reading the above, can anyone suggest what I was doing wrong that I could not get the temps changed for either probe? When they said to hit the SET button quickly, they sure mean it.
I'm going to try to reach Maverick customer service later in the week. If I do, I'll report back here.
