You have a roku device connected to the vizio tv? A roku stick, express, premiere or ultra? The direction are for you to go into the settings of the roku, not the tv, we are programming the roku remote to control the tv power and volume of the vizio. At the point of programming the remote you need the tv to view the home screen of the roku device, in the end it should be able to control the tv power and volume of the tv, nothing else on the tv itself, for that you would use the vizio tv remote.
