Commonly the AV key is used to select the input on the TV and most TVs use a menu to select from a list of inputs. When the AV key is pressed on the SKY Q Replacement Remote, and a TV and STB have been set up by code, the Menu Up, Down, Left, Right and OK keys will temporarily control the TV. If the OK key is pressed, or no key is pressed for ten seconds, these keys will revert to controlling the set-top box again.
The AV-feature is enabled as standard as soon as an STB and a TV are set up.
