• Turn counterclockwise and remove the reticle cover between the

eyepiece and focusing handwheel. This will expose four reticle set
screws.

• Loosen these four set screws equally with a screwdriver. Turn the

Assembly so that point A coincides with the vertical crosshair.

• Tighten these four set screws equally and observe whether any

transversal deviation appears when point A moves along the
vertical hair. If not, the adjustment is over.

• Assemble back the protective cover to its original position.
