Adjusting the Geometry:
1. Input an anamorphic cross-hatch test pattern to the projector.
2. Loosen the three Lens Rotation Set Screws (shown in Figure 3-19) on the lens

4. When the image geometry appears correct, tighten the three Lens
Rotation Set Screws to secure the lens in place. (When viewed from
the front, the rear opening on the anamorphic lens should appear
as a tall, narrow oval.)
