How do I watch TV?

This apartment is equipped with a TV that works with a TV box. The TV box receives all channels and sends them to the TV:

1. Turn on the TV box
2. Turn on the TV
3. When the TV displays a channel you can switch the channels using the TV Box remote control
4. If the TV does not display a channel, the TV is not set to the correct "Source". Change the source by pressing the source icon on the remote until the TV displays a TV channel. If the TV displays a TV channel you pick up the TV Box remote control to switch channels.
