FINAL ADJUSTMENTS (ALL INSTALLATIONS)
1.
Turn the projector on with the UH480 Lens out of the projector beam. Set the horizontal
lens shift to neutral (if a feature of your projector) and then adjust the ceiling mount so that the
16:9 image is in the exact center of and square to the screen, with a similar amount of image
slightly over the top and bottom screen borders. If the projector lens is not in the exact
horizontal center of the screen you may need to use a little horizontal lens shift for this purpose.
2.
Bring the UH480 Lens into the beam. Adjust the vertical position and tilt of the Lens so
that the projector beam is passing through the center of the Lens and so any residual
pincushion distortion is about the same at the top and bottom of the image. This will typically
result in the UH480 Lens being below the center of the projector lens and tilted slightly
downward. Tighten the knobs.
3.
Adjust the rotation of the ATH1 transport so that the left and right sides of the image are
an equal distance from their respective screen borders. Now tighten the Pivot Screw (M380)
and also the four remaining screws holding the transport to the Attachment Plate.
4.
For optimum multiple aspect ratio performance, adjust the projector’s zoom so that a
1.85:1 aspect ratio movie (Lens
“out”) is just masked by the top and bottom of the screen
border. This way 1.85:1, 16:9 and 2.35-2.4:1 aspect ratio movies should all be presented to fill
the screen at a constant height.
5.
Remove the protective film from the front of the Panamorph lens
