2.2 ASSEMBLY AND PREPARATION FOR USE
2.2.1 UNPACKING
The following steps must be taken prior to each use of the PVS-14.
1. Open the carrying case, remove the PVS-14, and inventory all items.
2. Inspect the monocular for obvious evidence of damage to optical surfaces, body, eyecup, eye
guard, power switch, battery cap, etc. Verify that all optical surfaces are clean and ready for use.
If necessary, clean with dry lens paper (wet or damp lens paper can damage the optics).
2.2.2 BATTERY INSTALLATION
CAUTION:
To protect the image intensifier when the monocular is in standby mode, off, or being operated in
daylight, always keep the objective lens cap securely fitted over the lens.
The PVS-14 operates with one AA battery. The battery is
not
supplied with the PVS-14 and must
be purchased separately by the user.
At operating temperatures below -20°C (-4°F), AGM does not recommend the use of Alkaline
batteries, 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).
