1st - change the dial's in the lighthouse. The numbers are 2 - 7 - 4 - 6 (from top to bottom). The best way is to set the numbers is to start from the first one. When the first is "2", change the third until you get a "7" in the second one. Then change the fourth util you get a "6". The next step is to change the second until you get a 4" in the third. Change the first one until you get the "2" and the "7" again.

2nd - activate the 4 radio's in the correct order. First: in the room below the electricity one. Second: in the room where's Stamina +. Third: inside the wagon next to the end of the second zipline. Fourth: next to the door where the allies are trapped.
