wSight the target Point A with telescope.

eUsing the telescope fine adjustment screws, move Point A to the edge of the

field of view by screw (point A’).

rNo adjustment is necessary if Point A moves along the vertical line of the

reticle.

Adjustments

qIf Point A is off from the vertical line of the reticle, first remove the eyepiece

cover.

wUsing the adjusting pin, loosen the four reticle adjustment screws slightly

loosening each screw by the same amount, and then rotate the reticle line

around the sight axis and align the vertical line of the sight axis with Point A’.
