When adjusting the boresight screws, ensure that the shutter is closed to avoid accidental
exposure to the projection beam when operating in close proximity to the projection lens. Open
the shutter only to view the test pattern.
6. Start with the horizontal boresight adjustment. Use the ILS controls to move the projection
lens into the projector, or turn the manual focus knob (F) counterclockwise to slightly defocus
the green cross-hair patterns (+) at the right and left edges of the test pattern.
7. Use the ILS controls or turn the focus knob (F) clockwise to begin focusing the image. Watch
for either the left or right cross-hair patterns (+) to come into focus.
8. If the left side comes into focus first, use a 5 mm driver to turn the horizontal boresight
adjustment screw (E) clockwise until the left and right are equally out of focus.
If the right side comes into focus first, turn the horizontal boresight screw counterclockwise.
9. Repeat steps 6 to 8 as required to obtain an even focus at the right and left edges of the
screen.
10. Next perform the vertical boresight adjustment. Use the ILS controls to move the projection
lens into the projector, or turn the focus knob (F) counterclockwise to slightly defocus the
green cross-hair patterns (+) at the top and bottom of the screen.
11. Use the ILS controls or turn the focus knob (F) clockwise to begin focusing the image. Watch
for either the top or bottom cross-hair patterns (+) to come into focus.
12. If the bottom comes into focus first, use a 5 mm driver to turn the vertical boresight
adjustment screw (D) counterclockwise until the top and bottom are equally out of focus.
If the top comes into focus first, turn the vertical boresight screw clockwise.
13. Repeat steps 10 to 12 as required to obtain an even focus at the top and bottom of the screen.
14. Once the correct focus has been achieved, lock the three lock screws.
When locking the lock screws, start with the horizontal lock screws (Lock A and Lock B) and
turn them until they just touch the base. Repeat for the vertical lock screw (Lock C). Continue
the gradual tightening of each screw, until all lock screws are tight.
When stabilizing image vibration, Lock B may be left locked or unlocked at the discretion of the
installer.
