In a DARK environment:  
How to Care for your Night Vision Device  
Step 6  
In the dark, remove LENS CAP.  
If you intend to store your unit for more than 24 hours, it is best to remove the batteries.  
Step 7  
Do NOT rotate EYEPIECE. No OBJECTIVE LENS rotation is necessary.  
You have already adjusted the EYEPIECE to your individual eyesight.  
This binocular is a fixed focus field view binocular,  
no focusing for distance is needed.  
Keep the unit in a cool, dry place.  
Clean lenses the same way you would your camera, with professional lens cleaning supplies.  
Step 8  
Click on the INFRARED button.  
A beam of infrared light, invisible to the human and animal eye, provides extra illumination.  
The lenses are optically coated and may be scratched if abrasive material is used or if dirt is  
rubbed into the glass. Do not touch lens surface with fingers.  
For technical assistance, call our customer service line at 1-800-444-5994.  
If you have any problems, call before returning the product to the store where purchased.  
Do not drop or expose to shock. The Intensifier Tube is made of glass.  
Do not disassemble or attempt to service the device. The power supply generates 17,000 volts inside!  
If your device needs repair, please refer to your warranty card.  
Do not leave inside car on a hot, sunny day.  
Image Quality  
The image you see through a Night Vision device is VERY DIFFERENT from the image observed  
using day-time binoculars. A Night Vision image is electronically amplified and then repro-  
duced on a phosphorus screen and therefore not as “clear” as a day-time binocular image.  
Clean exterior with a soft, clean cloth.  
If condensation is visible on the unit, return it to a normal temperature and wait until the con-  
densation disappears before using.  
Light and dark marks (spots) caused by the Electronic Intensifier Tube can be seen in the field  
of view. These are normal and are not defects in the Electronic Intensifier Tube.  
Image sharpness is also not consistent across the field of view. The image has very high  
resolution in the center. The image becomes more distorted toward the periphery of the image.  
Due to our sophisticated corrective optics, the amount of distortion in your Night Vision device  
is less then the distortion found in other Night Vision devices.

Use of the Infrared Illuminator in a closed room, or at close range, will exaggerate the light and  
dark spots on the Electronic Intensifier Tube. The Infrared Illuminator, although invisible to  
human and animal eyes, is very bright at close range when viewed through the device. This  
bright light exaggerates the spots on the Electronic Intensifier Tube. Testing your Night Vision  
device indoors with the Infrared Illuminator, at close range, is not representative of the  
performance of the device in its intended outdoor application.

Your Night Vision device works  
by amplifying available natural  
light. In complete darkness, with  
no available natural light, you  
cannot see without the use of the  
Infrared Illuminator (IR). The IR  
works like a flashlight, but is  
invisible to human and animal  
eyes.

Half-Moon  
Projected image is dim.  
A half-moon provides a substan-  
tial amount of ambient light to be  
amplified by the internal  
Electronic Intensifier Tube.  
Without the assistance of the IR,  
you can recognize a man-sized  
object about 100 yards away.

How Night Vision Works  
H
n
Light coming into the device from the direction of the object is gathered by the objective lens  
and focused onto the Image Intensifier Tube.  
NOB5X  
F
n
The front of the Image Intensifier Tube contains a photocathode which converts light into electrons.  
Quarter-Moon  
B
n
The device contains a very high voltage power supply, which converts the 3 volts supplied by  
the batteries into 17 kilovolts.  
A quarter-moon provides the  
minimal amount of ambient light  
to allow viewing unassisted by  
the IR. Without the IR illuminat-  
ed, a man-sized object can be  
recognized about 60 yards away.  
With the IR illuminated, this dis-  
tance is more than 100 yards.  
The IR will greatly improve target  
recognition.  
A

The high voltage hurls the electrons into the phosphorous screen. The phosphorous screen  
illuminates with an image when struck by electrons. The eyepiece optic then focuses the phos-  
phorous screen image to your eye.

Streetlights and headlights will  
generally not damage the  
Electronic Intensifier Tube, if a  
safe distance away. As a precau-  
tion, do not point the device  
directly into a light source. At a  
distance of more than 30 yards,  
most common man-made light  
sources will generally not dam-  
age the device.
