ially to the reflector until both light arcs are
equally sharp, as shown in Figure 3Ć6.
• Use SW 3 ball-headed screwdriver and the adjustĆ
ing screws for vertical (3Ć5ā/ā2) and lateral (3Ć5ā/ā3)
adjustment of the arc image beside the arc, as
shown in Fig. 3Ć6.
• Screw the objective in the nosepiece again.
