Wondering why you need to do this??? X1 boxes work better with X1 remotes when paired over RF.
X1 boxes can receive IR and RF simultaneously.
What is your situation?
I need to turn off the RF and turn on IR on this remote XR11
Rf needs turned off to use 3rd party remotes.
People who have high quality systems don't need or want the xfinity remote.
enter setup on your remote and enter 9-8-7 numbers.
