If yes, This is the correct aperture setting to use the lens on the projector, adjusting is not necessary.
If no, Continue with step 2 to preform the adjustment.
2. Loosen the hexagon screw (B). (image 3-9)
3. Rotate the aperture barrel (A) until the F2.5 arrow matches the arrow on the body image 3-9.
4. Secure the position of the barrel by tightening the screw.
