Advanced Optical Alignment - Christie M Series User Manual

4. Center the image on the screen: If the projector is mounted off center to the screen axis, then offset the
lens as much as required. Aim the projector over slightly towards the center of the screen, but use caution
when doing so, as too much tilt will cause excessive keystone distortion. Lens offset will not.
5. Verify side-to-side leveling: With the framing pattern on screen, double-check projector leveling so the
top edge of the image is parallel to the top edge of the screen.
6. Throw Distance: Ensure the projector is positioned in the throw distance range for the particular lens.
Folded Optics
In rear screen applications where space behind the projector is limited, a mirror may be used to fold the optical
path. The position of the projector and mirror must be accurately set - if considering this type of installation
call your dealer for assistance.
