3. Proceed to level the projector by adjusting the feet of the projector as follows:
• Loosen the nut (1) on the threaded rod of the three projector feet. Use a 17mm open wrench.
• Adjust the height of the 3 legs to level the projector. Use a 14 mm wrench to adjust the height as illustrated
(2).
• Secure the leg height by tightening the nuts (1) of each projector foot.

4. Later, when the projector is up-and-running, adjust precise image geometry and placement.
Projector tilting
In an ideal installation, the Athena lens surface is centered with and parallel to the screen. This orientation
helps to ensure optimized lens performance 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. In other words, use the SHIFT functionality of the Lens Holder prior to tilt the projector.
1. Before adjusting tilt, make sure the projector is as well-centered with the theatre screen as possible for the
installation area.
2. Check 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 nut (1) on the threaded rod of the three projector feet. Use a 17mm open wrench.
• Adjust the height of the 3 legs until the projected image matches the projection port window and the screen
tilt. Use a 14mm open wrench to adjust the height as illustrated (2).
