I have two RFRs for one of my theaters. I just got one up and running properly, but the second is having issues. It won't get past the initial start up screen. I can start it up holding "C" and reconfigure the network ID and the HF channel, but when I restart it, it still won't go beyond that first screen. Is there a way to reset that remote or something? Can you run two remotes on the same network?
