How to align a ceiling mounted CLM projector
1. Install the projector in the desired location. See "Suspension of the CLM projector with rigging clamps", page 25. Take into
account the zoom range of the used lens and the size of the screen.
2. Project one of the internal hatch patterns on the screen.
3. Adjust the height of the rigging clamps with respect to the projector, until the projected hatch pattern is rectangle shaped and
leveled. Separate skew adjustment is still possible.
