NIGHT VISION CHARACTERISTICS
MAINTENANCE
BLACK SPOTS
These are cosmetic blemishes in the image intensifier. They do not affect the performance
or reliability of a night vision device and a number of sizes are inherent in the manufacturing
process.
IMAGE INTENSIFIER LIFE
Night Vision Devices are designed to be robust. The image intensifier tube, however, does
not have an unlimited lifetime. The life of the image intensifier is dependent upon the
amount of use. Under normal operating conditions, it will provide reliable performance for
an extended period of time.
OPTICS
Always clean the optics with a suitable optical cleaning cloth. Do not use detergents or
excessive moisture to clean any part of the Night Vision Device.
BATTERY/BATTERY COMPARTMENT
Any Night Vision Device that is to be stored for a long or undetermined amount of time
must have the batteries removed.
MOISTURE
The Night Vision Device is water resistant. No warranties or guarantees apply to a Night
Vision Device that has been submerged in water. Take great care when using any night
vision in a wet environment as the image intensifier tube is sensitive to moisture.
SALT WATER
If the Night Vision Device is exposed to a salt water environment, wipe it off with a clean
cloth slightly dampened with fresh water and dry it thoroughly. Take special care of the
optics as noted above.
