Today I had to go back to customer's house that has 3 MX-980 that John helped me update yesterday.
One in the bedroom has DTV power off button that the other remotes/rooms do not.

3 times yesterday I asked my customer to test, reset the remotes when he called that telling me that that the updated button didn't appear on the remote, even though I demonstrated the feature, WHILE HE was holding the controller and pressing the button.
One of the things I asked him, 3 separate times, was which of the MX-980 remotes he was holding. Each time he tells me it was the one for the master bedroom.

So today, I show up and go to master bedroom and what do I find on the cradle? The living room remote, not the bedroom one.
Swapped remotes around and left.
It's a good thing that they weren't home as I was not a happy camper.
