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:

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.

To do this, loosen the Pitch Adjustment Levers (directly above the Height Adjustment

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:

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

into the screen frame area to mask the distortion.
