Installation
Height (Y) Adjustment: With the white field still on-screen, loosen the Height Adjustment
Levers on either side of the lens. Then, 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
When the height is properly set, tighten the Height Adjustment Levers to secure the lens in
place.
Pitch (Angle): Next, angle the lens to even out any top-to-bottom pincushion distortion.

Levers) 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 Levers to
secure the lens in place.
There may be some pincushion distortion even after the lens is

properly adjusted, especially at shorter throw distances. If this is the
case, Runco recommends that you slightly over-scan the image
