Projector tilting
In an ideal installation, the Prometheus lens surface is centered w ith and parallel to the screen. T his orientation helps to ensure
optimized lens performances with minimal offset. If this p osition is not possible (such as w hen the projector is significantly higher
than the center of the s creen), 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 s creen as pos sible for your installation area.
2. Check with theatre personnel for th
e degree of screen tilt, or measure this incline with a protractor at the screen.
3. Tilt the projector to closely m atch this screen tilt angle as follows:
- Loosen the nuts (A), using a w rench of 24 m m, on the threaded rod.
- Adjust the h eight of the legs until the projected image m atches the projection port window and the screen tilt.
- Secure the leg height by tightening the nuts (A).
