Later, when the projector is up-and-running, adjust precise image geometry and placement.
Projector tilting
In an ideal installation, the Prometheus III lens surface is centered with and parallel to the screen. This
orientation helps to ensure optimized lens performances with minimal offset. If this position is not possible
(such as when the projector is significantly higher than the center of the screen), it is better to rely on offset
rather than extra tilt.
1.
Before adjusting tilt, make sure the projector is as well-centered with the theatre screen as possible for your
installation area.
2.
Check with theatre personnel for the degree of screen tilt, or measure this incline with a protractor at the
screen.
3.
Tilt the projector to closely match this screen tilt angle as follows:
•
Loosen the nuts (A), using a wrench of 24 mm, on the threaded rod.
