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 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 con-
densation disappears before using.
In a DARK environment:
Step 6 In the dark, remove LENS CAP.
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.
Step 8 Click on the INFRARED button.
A beam of infrared light, invisible to the human and animal eye, provides extra illumination.

If you have any problems, call before returning the product to the store where purchased.
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.
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.
