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
T-Screws to secure the lens in place.
Geometry:
1. Input an anamorphic cross-hatch test pattern to the projector.
2. Unscrew the Anamorphic Lens just enough to allow it to rotate freely.
3. Grasp the lens by the center ring and rotate the lens until the image is properly
anamorphic:
4. When the image geometry appears correct, tighten the
Anamorphic Lens Set Screw (item #10) 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.)
Focus: Finally, rotate the Focus Ring on the anamorphic
lens to fine-tune the optical focus.
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.
