RF/IR Remote Question

I have 1 Roamio and 3 RF capable Mini's. When I pair a remote to its device is that remote unique to its device? Right now the bedroom mini remote seems to affect the living room Roamio. Our house isn't that big but each device is "hidden" so I'd like to have the ability to control each by RF remote independent of the other devices.

Please advise.

Thanks

Randy
