Silver Centering Circle:
When fully visible, the lens is centered and
functioning as a normal lens.
Rotating Head:
Rotates image 360 degrees.
Offset Screw:
Shifts lens assembly off the center axis 3.8mm.
Locking Screw:
Locks rotating head in position to maintain
projector alignment.
Installation Procedure:
1. Be sure that all projectors are level. When
using your KC lens you are moving the
inner optical cell of the lens rather than
tipping your projector up or down as you
would normally do in a multimedia show.
Some minor adjustments of your projector
stand may be required.
2. Using the Silver Centering Circle (figure 1),
center all lenses to be used.
3. Insert lenses into projectors.
