PECULIARITIES OF USE
Your night vision device is designed to provide many years of reliable service. To ensure high performance you
should adhere to the following rules:
• Do not direct the unit in the “on” position at intense sources of light, such as a car’s headlights or burning fire.
This may disable the unit for an unknown length of time or cause a dark spot in the center of the field of view.
Do not turn the unit on in daylight without the protective cap firmly secured over the objective lens, as this may
damage the unit.
• Any such damage may void the warranty.
• Never leave the unit in the “on” position over an extended length of time in an area with a light level exceeding
1-10 lux (twilight - 1lux, deep twilight - .001 lux). Please keep the protective cap on the objective under greater
light level.
• Your device was designed to be self-contained. Do not open the body of the unit or otherwise attempt to
service this device. If such need arises return the unit for replacement or repair.
• Protect the device from exposure to direct sunlight and extreme temperatures.
• Avoid dropping the unit. The device incorporates a sophisticated optical system which could be damaged in
extreme cases of misues.
• Clean optical parts (lenses) with professional lens cleaning supplies designed for use with multi-coated optics.
