How should the signal be mated to the projector?

The process of mating the signal to the projector requires it to be rotated until it is properly seated. This ensures that the signal is securely attached and aligned correctly for optimal performance. Proper seating is essential to maintain a tight connection, preventing any potential issues such as misalignment or disconnection during operation.

Rotating the signal into place helps to engage any locking mechanisms that may be present, ensuring that the components fit together snugly and securely. This method also minimizes the risk of damaging either the signal or the projector, which can occur if excessive force is applied inappropriately. The other methods, while they may imply a level of attachment, do not provide the necessary assurance of a stable and secure fit that comes with the rotational seating technique.
