Mr. Bill's Adventureland Review
The numbered blue dots on the map below are the locations where you turn on the antennae and place 2 settings into each control panel.

The picture below on the left shows that all 13 radar antennae have been turned on. The picture below on the right has been numbered to match the panels on the map above. Panel number 13 is the one on the other side of the broken part of the bridge (walkway).
Notice how the 2 symbols for numbers 3 and 12 antennae control panels as seen below were determined from the picture on the right above.
