5. Fine tune the focus of cross-hair pattern I by adjusting the appropriate capscrew, see
Locations. Adjust until the cross-hair image is in focus with minimal flare.
6. Adjust cross-hair pattern II, by adjusting the appropriate capscrew, see
until the cross-hair image is in focus with minimal flare.
7. Adjust cross-hair pattern III, by adjusting the appropriate capscrew, see
Adjust until the cross-hair image is in focus with minimal flare.
8. Repeat step 5, 6, and 7 as required until all 3 cross-hair patterns are in equal sharp focus. If the boresight is
acceptable, see step 11. If the boresight does not appear to be converging to an acceptable level of image
quality or if the lens will not focus over the correct range of throw distances, then the boresight requires
coarse adjustment, see step 9.
9. The original factory boresight can be recovered approximately by positioning the 3 setscrews, see
2-2 Screw Locations. Position the setscrews flush with the front face of the lens mount plate and in contact
with the inner lens mount plate. This may require adjusting both setscrews and capscrews.
10. If further action is required. Repeat #2.
11. Lock the setscrews so they do not shift, and re-check the boresight quality.
