Adjusting the Lens Height (Y):

1.Project a white field on the screen.

2.Ensure that the two Pitch/Y-Adjustment Screws are loose enough to allow vertical movement of the lens assembly.

3.Slowly move the anamorphic lens into place so that there are no shadows on the top or bottom of the screen:

Too Low

Correct position

Too High

4.When the height is properly set, tighten the Pitch/Y-Adjustment Screws to secure the lens in place.

Adjusting the Pitch (Angle): Next, angle the lens to even out any top-to-bottom pincushion distortion. To do this, loosen the Pitch/Y-Adjustment Screws on either side of the lens to allow it to pivot freely. Then, adjust the anamorphic lens angle so that the projected image is rectangular:
