over the objective lens when the device is not in use, or when it is
being used in daylight conditions.
• Keep the equipment clean. Protect it from moisture, dramatic
temperature drops, and electrical shocks.
• DO NOT force the equipment controls past their stopping points.
• DO NOT leave the equipment activated during breaks in operation.
• DO NOT store the equipment with the batteries installed.
• Thoroughly clean and dry each item before placing them into the
storage case.
NOTES:
• Do not test the device in daylight conditions for more than ten (10)
minutes, even with the daylight filter/ lens cap on.
• The purpose of the built-in IR illuminator is to provide additional
illumination when necessary while viewing scenes at close distances
(up to 3 meters).
• The equipment requires some ambient light (moonlight, starlight,
etc.) to operate.
• Performance of the device in nighttime conditions depends on the
level of ambient light in the environment. Please remember the
following:
- The level of ambient light is reduced by the presence of clouds,
shade, or objects that block natural light (trees, buildings, etc.).
- The equipment is less effective when operated in shadows and
other darkened areas.
- The equipment is less effective when operated in rain, fog, sleet,
snow, dust or smoke.
- The equipment will not “see” through dense smoke.

1.5 IMAGE INTENSIFIED NIGHT VISION
VERSUS INFRARED THERMAL VISION
Image Intensification “I2” works by collecting tiny amounts of light,
including the lower portion of the infrared light spectrum, that are
present but may be imperceptible to our eyes, and amplifying it to the
point that we can easily observe the image.
Thermal imagingtechnology operates by capturing the upper portion of
the infrared light spectrum, which is emitted as heat by objects instead
of simply reflected as light. Hotter objects, such as warm bodies, emit
more of this light than cooler objects, like trees or buildings.
The thermal vision device makes images from heat, not light, a feat
impossible for the naked eye or image intensified (I2) night vision
devices. This allows you to see clearly without any visible light. People,
animals, and objects all generate or reflect heat, and are clearly seen
by the thermal vision device, in even the most adverse conditions.
Thermal is best used to detect the desired object. It is the best 24-hour
imaging option.
Night vision devices provide a more natural image, wider field of view
(FOV), wider operating temperature, and longer battery life.

lens.
The BNVD lens is designed for the harsh outdoor environment and has
a coating for durability and anti-reflection, but it may require cleaning
occasionally. Avoid scratching the lens and/or leaving fingerprints on
the optics. Optics can be damaged by improper cleaning. Clean the lens
according to the instructions below when image quality degradation is
noticed or excessive dirt or other contaminant is on the lens.
Do not use abrasive materials, such as paper or scrub brushes as this
will possibly damage the lens by scratching it. Only wipe the lens clean
when there is visible contamination on the surface.
PREFERRED METHOD FOR CLEANING THE LENS
Materials:
• Optical-grade cloth
• Pure water (de-ionized or other)
• Isopropyl alcohol (IPA)
Saturate a piece of the lens tissue with the water and drape it over
the lens. Let the surface tension of the water pull the tissue onto the
lens surface and then drag the tissue across the lens surface. Repeat
several times with different pieces of tissue.
Repeat the same step using IPA instead of water. Drag the final piece
