Corrected entry: When Batman is in his plane and stealing the Joker's balloons, he flicks 3 switches to close the claw around the cables. If you look closely, you can see that the red light next to these switches is labelled "volume" - not really anything to do with the claw; and more to do with his stereo.

Correction: The red light has no labeling anywhere near it that says 'Volume', nor do any of the switches that he hits.
