Installation
Adjusting the Lens Height (Y):
1. Project a white field on the screen.
2. Ensure that the four Height (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
Too High
4. When the height is properly set, tighten the Height 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 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:
Incorrect Lens Angle
The anamorphic lens will almost always be angled with respect to the projector; this is
normal.
Once the proper lens angle has been set, firmly tighten the Pitch Adjustment Screws to
secure the lens in place.
