3 The NVG requires some Night light (moonlight, starlight, etc.) to operate. The level ofperformance depends upon the level of light. Night light is reduced by passing cloud cover, while operating under trees, in buildingshadows, etc. The NVG is less effective viewing into shadows and other darkened areas. The NVG is less effective through rain, fog, sleet, snow, smoke, and other reflectivematerial. The NVG will not see through dense smoke. Adjust vehicular speed to prevent overdriving the range of view when conditions of possiblereduction or loss of Vision not carry batteries in pockets containing metal objects such as coins, keys, objects can cause the batteries to short circuit and become very hot. In the caseof lithium batteries, a short circuit could cause them to of ExplosionThe BA-5567/U lithium battery contains sulfur dioxide gas under pressure and should be handled in thefollowing manner: Do not heat, puncture, disassemble, short circuit, attempt to recharge, or otherwise tamperwith the batteries.

4 Turn off the equipment if the battery compartment becomes unduly hot. If possible, waituntil the batteries have cooled before removing them. The batteries have safety vents to prevent explosion. When they are venting gas, you willsmell it (very irritating) or hear the sound of gas escaping. When the safety vents haveoperated, the batteries are fairly safe from bursting, but will be hot and must be handled withcare. If you inhale sulfur dioxide, seek medical 11-5855-262-23&P-2bWARNINGT oxic MaterialThe image intensifier s phosphor screen contains toxic materials. If an image intensifier breaks, be extremely careful to avoid inhaling the phosphor screenmaterial. Do not allow the material to come in contact with the mouth or open wounds onthe skin. If the phosphor screen material contacts your skin, wash it off immediately with soap andwater.
