2.5 System Limitations

reduce natural night light and negatively affect the efficiency and operation of the NM-108 BC in-
clude: rain, fog, sleet, snow, and smoke; passing cloud cover and objects that produce shadows; and
low-contrast environments such as snow-covered territory, sandy deserts, large bodies of water or
grassy hills.

CAUTION:
To protect the image intensifier tube when the device is not in use or when it is being operated
in daylight, keep the protective objective lens cap securely fitted over the lens.
3.1.1 NM-108 BC Battery Installation
NOTE:
At operating temperatures below -20 °C , alkaline battery life will be severely reduced. Under
said conditions, the use of lithium battery is recommended.
CAUTION:
Ensure that the device is off before installing a battery.
Install the battery as follows (refer to Figure 3-1):
1. Unscrew the battery cap (E) and check the position of the adapter (D). See Figure 3-2 for the cor-
rect positioning of the threaded adapter, which changes depending on the battery being installed.
2. If necessary, change the adapter position in the cap. Use the special wrench.
