I have the trailer for Armada Prime, the one which folds apart into a minicon station. I see and can work the electronics/sounds from the buttons near the clear display, and the goldish peg which a minicon goes on. However, I've noticed on the side of the main part, just above the batteries is a clear plastic thing, which has some sort of switch behind it. The switch is black and has a silver "X" on it. Anyone know what this does, or how to activate it?
