Which component should be rotated until seated when mating the distress signal to a projector?

• A. The projector
• B. The signal
• C. The battery
• D. The cover

Answer: (B)

Rotating until seated is how a twist-lock or bayonet-style mating connection is secured. The distress signal is designed to engage with the projector through a locking interface, so turning it until it seats aligns the electrical contacts and locks the two pieces together. This ensures a reliable connection that won’t loosen with vibration or movement at sea. The projector itself isn’t the piece that needs to be rotated to mate; it serves as the receptacle for the signal. The battery powers the system and isn’t involved in the mating action, and the cover is simply protective or part of access—not something you twist to seat the signal. If the signal isn’t seated, the connection can be unstable or fail when you need it most.
