3.3 ASSEMBLY AND PREPARATION FOR USE
3.3.1. UNPACKING
The following steps must be accomplished prior to each mission where the MUNVM is used.
CAUTION
:
Relieve air pressure inside shipping and storage case by pressing in on opposite sides of the
case before releasing latches.
(1) Release the latch securing top of shipping and storage case and open.
(2) Check contents for completeness (see Figure 2-1).
(3) Remove carrying case. Open carrying case (Figure 2-3), remove MUNVM, and check contents for
completeness.
(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. Clean with
lens paper.
3.3.2. INSTALLATION OF BATTERY
CAUTION
:
To protect the image intensifier, keep the objective lens cap on when the monocular is not in
use or when using the monocular in daylight conditions.
The MUNVM operates with one AA battery. Battery is not supplied with the MUNVM and must be ob-
tained separately.
At operating temperatures below -20°C (-4°F), Alkaline batteries are not recommended, as operating
life will be severely reduced. Lithium-iron disulfide L91 1.5V AA batteries should be used below -20°C
(-4°F).
