3. Physical installation
2. If a
fi
lm projector is already present (projector will be off-center), try to optimize aim (see ref B image 3-2).
Note:
Unlike
fi
lm projectors, it is best to keep the projector lens surface as parallel to the screen as possible, even if it is
signi
fi
cantly above the screen center.
The off-center position slightly increases side keystone, but will minimize horizontal lens offset required.

3. Proceed to level the projector by adjusting the feet of the projector as follows:
-
Loosen the nuts (A), using a wrench of 24 mm, on the threaded rod.
-
Adjust the height of the 4 legs (B) to level the projector, using a 17 mm wrench.
-
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.

4. Later, when the projector is up-and-running, adjust precise image geometry and placement.
Projector tilting
In an ideal installation, the B-series projector 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 signi
fi
cantly
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.
-
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).
