Watching live TV channels is very simple, all you have to do is choose the ‘Live
TV’ app on the Apple TV.
The app will open to the channel list. You can use the navigation keys to
choose which channel you would like to watch, the up and down buttons will lead
to different categories. When watching a channel pressing the left or right buttons
will bring up the navigation to choose a new channel, as will the Ok button.
How do I exit the Live TV app?
Exit the Live TV app and any other app simply by pressing the ‘Return’ arrow on the
remote control - some apps may require it to be pressed a few times.
