NeilWillis Posted June 14, 2015 Posted June 14, 2015 There is a switch on the sight you need to operate to turn on the sight, and another for the graticule. The first is a toggle switch on the right side of the sight, and the second is on the bottom, and has a rheostat - the small round knob close to the second switch.
