NOTE:
The helmet mount provides two positions for the user to position the MUNVM. The ipped
down position allows the user to position the MUNVM directly in front of the eyes. The helmet
mount also allows the user to rotate the MUNVM to a ipped up position when the MUNVM is
not needed for immediate use. Both the ipped down and the ipped up positions have a posi-
tive stop which assures the user that the MUNVM is in the correct position.
Perform the following procedures for helmet mounted operation.
(1) Ensure that the battery are installed per paragraph 3.3.2.
(2) Don the helmet mount per instructions in paragraph 3.3.8.
(3) Place the monocular in the socket of the helmet mount.
Set your eye relief by depressing the side buttons (or press down on side lever on metal mount) (see
Figure 3-20) and carefully move the monocular fore or aft until the eyecup comfortably seals around
the eye. Readjust the helmet straps as required for vertical adjustment.
(4) Turn power switch to ON. Adjust the tilt by using the tilt adjustment lock knob (or tilt adjustment
lever on metal mount) (Figure 3-20) until you obtain a comfortable viewing angle.

erly focused.

lever on metal mount) and sliding monocular fore or aft to obtain a full eld-of-view of the image. Reset
the diopter adjustment for best image.
