My 622 was replaced with a 722 due to a defective HDMI port. I was able to get IR Remote 1 (green) working with the new unit easily, but for some reason, I can't get UHF Remote 2 (blue) to work. It was working fine with the 622 before the swap. The addresses are the same (1). I've tried every method in the materials to get the two units to work together, but it's as if they're just not talking to each other. I can get the remote to change addresses but it will not transmit that info to the 722 when I press "record". Conversely, I set the remote to address 1 to match the 722's default address, but there's no response. The remote is a 6.3 IR/UHF PRO. Both the remote and the receiver are on band A. Dish tech support wasn't able to help and they're sending out a replacement unit. Anybody have any suggestions? I've removed the batteries and thought maybe letting it sit overnight might "clear" the problem.
