Avionics Switch, Fly The Airbus A380

When I downloaded the payware, "Fly The Airbus A380", and when I tried the Adventure Manager, which turns everything off in the cockpit, The radios can't seem to work. I assume that I need to turn the avionics switch on but I can't seem to find it. I looked through all the panels. Can someone who also uses this product tell me where the avionics switch is located or what button do I need to press on the keyboard to activate it? Thanks!
