3. Turn in the three set screws indicated with reference 11 image 10-11 without disturbing the projected image. Tighten lightly . Do
not turn in the set screw at the lower left of the Lens Holder!
Note: Ensure that the edges of the projected test pattern remain in place on the screen. Any movement of the image will affect
the Scheimpflug adjustment.
4. Fasten the lock nut (reference 21 image 10-11) of the three set screws. Use a 10mm nut driver. Ensure the image doesn't move.
