I'm using a Radio Shack 15-2116 remote and am trying to set up the macros. The remote has no buttons labeled for the macros. The manual says to select any button on the remote for the macro button. The remote wont let me use any of the device buttons for this. So the only buttons that I have been able to use so far for macros are the numbered buttons. When i do this, this then makes that button useless for anything else. Can't use the button now for entering channel numbers. Does this make sense? Am I missing somthing here or is this just a poorly designed remote.
