The media centre gives you simple help to show what you want on the TV in the hall. Use the buttons on the “Stream Deck” controller to move through the menus and control apps. You can also use the keyboard.
Don’t forget to press the close button after using an app. The “Help” button on each page will take you directly to information about that app.
To mute the sound, click the volume knob.
If it all goes wrong, press the “Reboot” button on the welcome page.
