3. Physical installation
2. If a film pro jector is already present (projector will be off-center), try to optimize a im (see ref B image 3-2).
Note: Unlike film projectors, it is best to keep the projector lens surface as parallel t o the screen as possible, even if it is
significantly above the screen center.
The off-center position slightly increases s ide keystone, but will minimize horizontal lens offset required.

3. Proc eed to level the pr ojector by adjusting the feet of the projector as follows:
- Loosen the nuts ( A), u sing a wrench of 2 4 m m, on the t hreaded rod.
- Adjust the height of the 4 legs (B) to level the projector, using a 17 mm wrenc h.
- Secure the leg height by tightening the nuts (A) .
Note: There must be at least 5 cm between the bottom side of the projector and the pedestal.

Projector tilting
In an ideal installation, the B-series projector lens surface is centered with and pa r a llel 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 s ignificantly
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. C heck with theatre personnel for the degree of screen tilt, or measure this incline with a protractor at the screen.
3. Tilt the pro jector to closely m atch
this screen tilt angle as follows:
- Loosen the nuts ( A), u sing a wrench of 2 4 m m, on the t hreaded rod.
- Adjust the height of the legs until the projected image matches the projection port window and the screen tilt.
- Secure the leg height by tightening the nuts (A) .
