Change the IR code on one of the recevers as well as in the sling configuation a/v setup wizard. There are instructions on how to do each on the forums. You'll find them with a quick search......

You'd probably have to change the loaded IR codes for at least one of your IRDs in your home automation system to match the change you make as per my previous post.

Although I don't mind helping; I do get a tad frustrated when asked to spoon feed another member.

So I suggest you use the search button as I just did to confirm the information was indeed on the site and located without issue....
