(3) Align the headmount/helmet mount adapter’s latch to the headmount socket (Figure 3-19). Press
and hold down the latch lever while installing the monocular into the headmount socket.
Release the latch when the monocular fully engages the socket.
(4) Set your eye relief by depressing the eye relief adjustment (Figure 3-19.) and move the monocular
back toward your non-do-minate eye until the eyecup comfortably seals around the eye.
(5) Turn the monocular ON.
(6) Readjust the vertical adjustment (Figure 3-9) of the headmount until the monocular is properly
aligned with your eye.
NOTE :
The sharpest image will be observed only when the objective lens and eyepiece lens are prop-
erly focused.
(7) Rotate the diopter adjustment for the clearest view of the image intensifier screen.
NOTE :
Any readjustment of eye relief requires readjustment of the diopter.
(8) Adjust the eye relief distance by pressing the eye relief adjustment and sliding monocular fore or aft
to obtain a full field-ofview
of the image. Reset the diopter adjustment for best image.
(9) Adjust the objective lens focus (Figure 3-1) while observing an object until the sharpest image is
obtained.
3.4.3. HELMET MOUNTED OPERATION
CAUTION :
Take some precaution when using/handling the helmet mount. Most damage occurs when the
helmet mount is left on the helmet when not needed for immediate use. Observe the following
cautions to significantly extend the useful life of the helmet mount.
CAUTION :
• Do not use excessive force when changing the up/down position of the MUNVM. Excessive
force can break the headmount/helmet mount adapter.
• Do not drop or throw the helmet with the helmet mount attached to it.
• With the monocular in the flipped up position, do not flick the monocular down by shaking the
helmet. This places significant stress on the helmet mount.
• All Other Services – Return the helmet and the helmet mount to unit maintenance for direct
mounting of the bracket via the helmet screws.
NOTE :
The headmount/helmet mount adapter allows the MUNVM to be rotated from the left to the
right eye or vice versa. The MUNVM can be moved to the flipped up position with the head-
mount/helmet mount adapter positioned to either the left or the right.
