Where are instructions for NFL Sunday Ticket?

I don’t see any instructions that I can learn how to use and watch the NFL Sunday Ticket!  There are no instructions I’m aware of. Can you choose the teams that are shown in the Game Mix channels?  No. If so, how?  Can you choose only 2 teams to watch at the same time?  If you mean only show 2 on the mix channel, no. When watching the Game Mix channel, how do you choose which game has the sound?  That may depend on your receiver but the game with sound should be highlighted. If not, pressing the select button works for me. You can move the highlighted game with the arrow keys. The sound matches the highlighted game. While watching the Game Mix, can you choose one of the games to watch for a few minutes in full screen and then go back to either 4 games or 8 games view? Sure. You can select any of the mix games. Just press the “prev” button on the remote to return to the game mix.
