In a DARK environment:
Step 6
In the dark, remove LENS CAPS.
Step 7
Do NOT rotate EYEPIECES.
Step 8
Click on the INFRARED button.
A beam of infrared light, invisible to the human and animal eye, provides extra illumination.
Step 9
Move the FOCUS ADJUSTMENT KNOB to Focus on a specific object.
NOTE: Model # NONB2FF does not require this step.
Warning:
When the power is turned OFF, the image will not immediately disappear. It will remain
visible for up to several minutes as the tube discharges. The discharge (fading of image) will
be faster in higher light environments, slower in the dark.

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.
IMPORTANT: You may see spots or other anomalies on the image when testing in a lighted
environment with the lens cap on.
When using the device in the field with the lens caps removed, many of these anomalies will
disappear. Testing indoors, with the lens caps affixed, focuses the light into a narrow beam
through the center of the image intensifier tube; this causes light to reflect inside the device to
produce spots on the phosphorus screen that many times will not be visible in the field.
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.
