4. Detector Crude Alignment:
Refer to Figure 17 for all the following instructions.
a. Use 3/16” Allen screwdriver to loosen up the 3 socket set screws (7).
b. Tilt the Flash Source in the general direction of the Detector.
c. Rotate the Periscope (4) until its ocular is positioned in front of your
aiming eye for most convenient observation.
d. Observe through the Periscope (4) and locate the Detector in the
center of view of source unit.
e. Tighten three socket set screws (7) of the Detector’s Swivel Mount.
5. Release the Fastening Screw (3) and remove the Telescope from the
Detector.
6. Flash Source Crude Alignment
Repeat Steps 3 through 4 for the Flash Source.
7. Flash Source Fine Adjustment:
a. Release the Adjustment Screw Securing Nuts (10) from all Adjustment
Screws (8,9) to enable fine alignment.
b. Watch through the Periscope (4). The cross midpoint inside the
Telescope Lens should be aimed to the opposite unit (Flash Source)

Telescope Sight Mounting (Figure 17, item 2).
d. Carefully secure the four Adjustment Screw Securing Nuts (10).
Release the Fastening Screw (3) and remove the Telescope (1) from
the unit.

Repeat Steps 3 and 7 for the Detector.
9. Repeat steps 3,7 and 8 if additional Adjustment is required.
10. Upon alignment completion perform the following:
a. Reinstall Protective Sight Covers on the Detector and the Flash
Source by screwing four Sight Cover screws (Figure 16, item 6).
b. Return the Telescope to its Original case.
