3. Turn screws 3 one revolution in or out (choose a direction to start) and adjust screw 1 and screw 2 again for maximum light output.
4. Is the new maximum higher than the previous one?
If yes, you adjust in the correct direction. Repeat step 3 in the same direction as many times as necessary until the new maximum
is lower then the previous one. Then go to step 5.
If no, you adjust in the wrong direction. Return one revolution and repeat step 3 by turning in the other direction.
5. Turn screw 3 one revolution back.
6. Check the brightness uniformity. In most cases it will be OK.
If not OK, turn slightly on the adjustment screws 1 and 2 until a uniform brightness is obtained.
- Screw 1 will correct the difference between the left and the right side of the projected image.
- Screw 2 will correct the difference between the top and the bottom side of the projected image.
Check again and repeat if necessary.
7. When the adjustment is finished, secure the position by turning the security nuts (A) against the plate (hold on the screws while
securing the nuts).
