When adjusting the boresight screws, ensure the shutter is closed to avoid accidental exposure
to the projection beam when operating in close proximity to the projection lens. Only open the
shutter to view the test pattern.
6. To 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 in the images in step 2)
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 in the images in step 2) 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, turn the horizontal boresight adjustment screw (E in the
images in step 2) 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. To perform the vertical boresight adjustment, use the ILS controls to move the projection lens
into the projector, or turn the focus knob (F in the images in step 2) 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 in the images in step 2) clockwise to begin
focusing the image.
Watch for either the left or right cross-hair patterns (+) to come into focus.
12. If the bottom comes into focus first, turn the vertical boresight adjustment screw (D in the
images in step 2) 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 (locks A and B in the
images in step 2) and turn them until they just touch the base.
