2.2 Zeroing The sight is delivered with the red dot in a centered position. Normally, this means that only small adjustments are necessary, provided the weapon rail is properly aligned. NOTE: Before performing zeroing, ensure the ballistic compensation lever (1) is set to “position A” (oriented horizontally and toward the gunner as shown in Fig. 5). a) Turn the intensity switch (9) clockwise until the red dot has sufficient intensity.

The intensity switch (9) can be more difficult to operate than at normal temperatures. • Salt air: no special procedures required.
4 TROUBLESHOOTING The red dot does not appear or has disappeared Make sure contact surfaces in the battery compartment are clean and verify that a working battery (16) is installed correctly according to 2.1.
