I have a new client that bought an existing clients home with an old RTI system that has an RP-1 with a T2+. T2+ was beat to hell, so we sold him a T2i to replace it in Dec. Got a call back that the remote isn't controlling anything anymore. The remote does page flips. The RP-1 doesn't show any RF activity when a button is pushed. We haven't sold RTI for over a decade, other than takeover projects, so I don't have an RF processor to test with. Is there any way to test if the remote is giving out an RF signal?
