3.3 ASSEMBLY AND PREPARATION FOR USE
3.3.1. UNPACKING
The following steps must be taken prior to each mission in which the MUNVM is used.
CAUTION :
Relieve air pressure from inside the shipping and storage case by compressing opposite sides
of the case before releasing the latches.
(1) Release the latch securing the top of the shipping and storage case and open it.
(2) Verify that all items were shipped (see Figure 2-1).
(3) Open the carrying case (Figure 2-3), remove MUNVM, and inventory the items.
(4) Inspect the monocular for obvious evidence of damage to optical surfaces, body, eyecup, eyeguard,
power switch, battery cap, etc. Ensure that all optical surfaces are clean and ready for use. If necessary,
clean with dry lens paper.
3.3.2. INSTALLATION OF THE BATTERY
CAUTION :
To protect the image intensifier, keep the objective lens cap securely fitted over the lens when
the monocular is not in use or when it is being operated in daylight conditions.
The MUNVM operates with one AA battery. The battery is not supplied with the MUNVM and must be
obtained separately.
At operating temperatures below -20°C (-4°F), Alkaline batteries are not recommended, as the battery
life will be severely reduced. Lithium-iron disulfide L91 1.5V AA batteries should be used in conditions
below -20°C (-4°F).
