I am hoping that someone can help me. I have a cable box from teh Pace company. Some of the buttons on the remote simply cannot be learned by my Pronto Pro. Yet I see on the board that there are CCF files that others have managed to sucessfully learn. Why is the Pronto Pro so sensitive when it comes to learning remote codes and is there any tricks. I have tried doing it in a dark closet etc but it simply will not learn the codes.
