I'd like to program my 422-3 to change channels on my DirecTV receiver by pressing a single button, but I can't find the instructions. How can I do that? [I'd like to program the star, circle, etc. buttons]
I am not sure what you want to do to change your SAT channels. You should contact us at our email address for support.
All buttons on a particular device code are not necessarily active. To see if a button is active and can be programmed, press the device button then press any key to see if it is active. If it is active the red LED will blink. This mainly applies to the colored and lower buttons.
