2. PREPARATIOnS FOR OPERATIOn
wARnIng :
the nemesis night vision weapon sights are designed for several years of reliable service. to
ensure trouble-free performance, please observe the following instructions:
• Do not activate the device in daylight unless the protective lens cover is fitted securely over
the objective lens If the device is ON, do not direct the device towards bright light sources, such
as car headlights, camp fires, street lights, etc., as this will cause damage to the device.
• Do not check the device’s operation in daylight unless the front lens cap is fitted securely
over the lens, and even, the device should only be ON for the few seconds it takes to establish
correct operation.
• Do not open the body of the device or otherwise disassemble it.
• Avoid dropping or otherwise impacting the device.
• Do not expose the device to moisture or extreme temperatures.
• Do not touch the lenses. Clean optical parts with a clean, soft cloth, and only use professional
lens cleaners designed for use with optics.
• Do not forget to remove the battery from the battery compartment if the device is to be
stored for more than 3 days.
• Do not forget to turn the device off during periods of non-operation.
wARnIng :
consider the following information and restrictions in order to avoid damaging the device
and to ensure a long service life and failure-free operation:
• Performance of the device in nighttime conditions depends on the level of ambient light.
Some light (moonlight, starlight, etc.) is required for the device to provide an image.
• The level of ambient light is reduced by the presence of clouds, shade, or objects that block
natural light (buildings, trees, etc.).
• The device loses its effectiveness when operated in shadowed areas.
• The effectiveness of the device is adversely affected by weather conditions such as rain,
snow, sleet, and fog, as well as environmental conditions such as smoke or dust.
• The device’s resolution level is reduced in environments with very low light conditions. The
visibility will degrade significantly under starlight conditions, particularly in low-contrast envi-
ronments such as deserts, large areas of uniform vegetation, etc.
• The device is equipped with a protection system that will automatically disable the image
intensifier tube when the illuminance level stays above 40 lux for over 10 seconds.
