It is recommended that top/bottom boresight be completed before horizontal boresight.
NOTE:
Typically,
horizontal boresight does not require adjustment. It should only be adjusted if a large horizontal angular offset
to the screen is required
.
Figure 4-2 Top/Bottom Image Adjustment
1. Tap the Test Patterns button on the Main Panel .
2. Tap All Test Patterns .
3. Tap DC2K Framing .
4. Loosen the set screw with a 5mm hex key. ( Figure 4-2/B ).
5. Turn the vertical adjust cap screw 1/8 of a turn counter-clockwise with the 5mm hex key. ( Figure 4-2 / A ).
6. Adjust both left and right horizontal adjusters by half the number of turns, in the opposite direction of the
vertical adjust ( Figure 4-3 ). For example, if the vertical adjust cap screws was turned 1/8 of a turn, the left
and right horizontal cap screws should be turned 1/16 of a turn in the opposite direction .
7. Check the screen. If the projected image is worse than before the adjustment was made turn the vertical
adjust cap screw 1/8 of turn clockwise. Ensure the left and right horizontal adjusters are adjusted equally in
the opposite direction to correct axial focus.
NOTE:
The 1/8 of a turn is a suggestion only and can be less
if needed; however, it should never be exceeded. Always compensate both left and right horizontal
adjustments according to the vertical adjustment.
8. Always observe the screen after each adjustment. If necessary, continue to make adjustments until both top
and bottom are equally sharp. Remember to adjust left and right horizontal adjusters in the opposite
direction each time. This ensures the lens is in the same relative position.
9. When the top and bottom of the image are equally in focus lock the set screw to hold that position.
Recheck the image.
10. If fine tuning is required, focus the image at the left and right sides. See 4.6 Adjust Horizontal Boresight,
on page 4-3 .
4.6 Adjust Horizontal Boresight
Only adjust vertical boresight 1/8 of a turn or less at one time to maintain
optimal lens performance (i.e. factory setup of absolute lens distance to the prism). It is
critical that you count each turn of the cap screws to ensure accurate adjustment.
Horizontal boresight should only be adjusted if a large horizontal tilt to the screen is required
