What should I do if the remote won't change channels on my device?

Make sure the remote is in the correct device category mode (TV, SAT/CBL, STREAM, B-RAY/DVD, AMP, or AUX) that controls the channels. You may also need to try pressing the ENTER button after entering a channel number, as this is a requirement with certain models and brands of TVs and cable/satellite boxes. (Page 15)
