Quick Start
GET FAMILIAR WITH THE DEVICE -HOW TO FOCUS YOUR NIGHT VISION DEVICE
In a LIGHTED environment:
Step 1 Install Battery [A] (battery not included).
Step 2 DO NOT REMOVE the LENS CAP [E].
The pinhole [F] in the lens cap lets through a small amount of light.
Removing lens cap in daylight could damage the unit.
Step 3 Rotate both EYEPIECE [C] and OBJECTIVE LENS [D] clockwise until they stop.
Step 4 Press POWER [B] button to turn device on.
Lens cap should still be installed on the device.
Step 5 Look through the EYEPIECE [C].
Look at an object across the room, and rotate EYEPIECE until object comes into focus.
Important:
In LIGHTED conditions, Rotating OBJECTIVE LENS, with lens cap on, will not effect focus or clarity
of image. Do not rotate OBJECTIVE LENS yet.
Activating INFRARED has no effect on image.
In a DARK environment:
Step 6 In the dark, remove LENS CAP [E].
Step 7 Do NOT rotate EYEPIECE [C]. Rotate OBJECTIVE LENS [D] until objects come into focus.
You have already adjusted the EYEPIECE to your individual eyesight.
Rotate the OBJECTIVE LENS to focus on objects at varying distances.
Step 8 Click on the INFRARED [G] button.
A beam of infrared light, invisible to the human and animal eye, provides extra
illumination.

Image Quality
The image you see through a Night Vision device is VERY
DIFFERENT from the image observed using day-time monoculars. A
Night Vision image is electronically amplified and then reproduced
on a phosphorus screen and therefore not as “clear” as a day-time
monocular image.
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.
Typical Image Appearance
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.
Frequently Asked Questions
Why are the projected images always green using Night Vision technology?
Night Vision phosphor screen is purposefully engineered because the human eye can differentiate
more shades of green than other colors.
How should I care for my Night Vision device?
Do not operate in lighted conditions, device is for use in the dark.
Do not drop the device. The internal intensifier tube is made of glass and is sensitive to impact.
Why do you focus both the front (Objective lens) and Eyepiece (Ocular)?
You do not see through the Night Vision device, like a pair of binoculars. Rather, you see an image
on the phosphor screen on the back of the tube. The objective lens focuses the image on to the front
of the intensifier tube. That image is then converted into electrons. The electrons strike the
phosphorous screen converting electrical energy into a visible image. The eyepiece focuses your
vision on to the image on the phosphorous screen.
What is the effective range of Night Vision?
Maximum range is up to 700 ft. depending on the model. The maximum viewing distance depends
on the environmental conditions. Overcast conditions, fog or rain will reduce the effective distance
you can see. The Infrared Illuminator will increase viewing range, especially in areas of complete
darkness where there is no ambient light.
What is the maximum effective distance of the Infrared Illuminator?
75 to 125 yds. The farther the object, the less intense the infrared light will be on the target.
Are Night Vision devices safe?
Night Vision products include shield-encased image intensifiers. The infrared illuminator utilizes light
emitting diodes (LED’s) operating in the infrared range and will not harm your eyes like a laser.
CAUTION: Do not point Infrared Emitter directly into eye at close range.
The infrared Emitter emits a BRIGHT, although invisible, beam of light.
As with any bright light, do not point into the eye.
Recognize that the image produced on the phosphorous screen can be very bright. Staring into a very
bright light causes the pupil to constrict. Your eye needs time to adjust to ambient light.

When can I expose the unit to light?
For demonstration purposes there is a pinhole in the lens cap, which enables you to power on the unit
in the light. The lens cap can be taken off during daylight, but the unit has to be off.
What is Generation 1? How does it differ from other Generations of Night Vision devices?
Generation 1, 2, 3 and 4 all employ electron bombardment technology. All of these technologies
convert light into electrons and reproduce the image on a phosphorous screen.
Generation 1 produces a higher resolution image than Generation 2.
Generation 3 and 4 are used by the United States Military and are very expensive.
Generation 2, 3 and 4 use a fiber optic device and/or special chemicals to further amplify light.
Performance under Various Light Conditions
Complete Darkness
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
A half-moon provides a substantial 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.
Quarter-Moon
A quarter-moon provides the minimal amount of ambient light to allow viewing unassisted by the IR.
Without the IR illuminated, a man-sized object can be recognized about 60 yards away. With the IR
illuminated, this distance is more than 100 yards. The IR will greatly improve target recognition.
Urban Environment (with man-made light sources)
Streetlights and headlights will generally not damage the Electronic Intensifier Tube, if a safe distance
away. As a precaution, 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 damage the device.
Troubleshooting
Unit may require several seconds after power-on for image to appear. This is normal.
Focus Problems
Try in lighted environment with lens cap on.
Are you able to focus the eyepiece?
• YES - Use in dark with lens cap off but do not rotate eyepiece.
• NO - Call our Customer Service Line
Unit does not turn on.
Light does not illuminate when button is pressed.
• Check to see if batteries are installed correctly
• No batteries
• Dead batteries
• Power light on, but no image
• Unit could be defective, call our Customer Service Line
Image is too dark
• Use the Infrared (IR) Illuminator
• Take off the lens cap
Projected image is dim.
• Batteries are low – insert new batteries

How Night Vision Works
Light (like moonlight or starlight) coming into the device from the direction of the object is gathered by
the objective lens and focused onto the Image Intensifier Tube.
The front of the Image Intensifier Tube contains a photocathode which converts light into electrons.
The device contains a very high voltage power supply, which converts the 3 volts supplied by the
batteries into 17 kilovolts.
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 phosphorous screen
image to your eye.
How to Care for your Night Vision Device
If you intend to store your unit for more than 24 hours, it is best to remove the batteries.
Keep the unit in a cool, dry place.
Clean lenses the same way you would your camera, with professional lens cleaning supplies.
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.
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 a car on a hot, sunny day.
Clean exterior with a soft, clean cloth.
If condensation is visible on the unit, return it to a normal temperature and wait until the condensation
disappears before using.
