Powering on the desk and related components

How to turn the desk on:

Walk into the booth, turn right, and look straight ahead. On the tall black rack straight ahead (with cords crisscrossing the top), there will be a big green button next to a big red button with a key sticking out between them. Press the green button to turn the DiGiCo board on. 

Take the cover off and stick it into the area of the desk behind the DiGiCo.
