2. If a film projector is already present (projector will be off-center), try to optimize a im (see ref B image 4-2).
Note: Unlike film projectors, it is best to keep the projector lens surface as parallel to the screen as pos sible, even if it is
significantly above the screen c enter.
The off-center position slightly increases side keystone, but will minimize horizontal lens offset required.

3. P roceed to level the pr ojector by adjusting the feet of the pr ojector 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, u sing 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.

Projector tilting
In an ideal installation, the DPxK BLP series projector lens surface is centered with an d para 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
significantly higher than the center o f the screen), it is better to rely on offset rather than ex tra tilt.
1. B efore adjusting tilt, mak e s ure the projector is as well-centered with th e theatre screen as possible for your installation area.
2. Check with theatre personnel for the degree of s creen tilt, or measure this incline with a pr otractor at t he 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 w indow and the screen tilt.
- Secure the leg height by tightening the nuts (A).
