General information on NightVision devices.
This electro-optical device assists in viewing in near darkness or com-
pletedarkness. It works byamplifying the already existinglightof the moon
or the stars. If no light is present the illuminator acts as an external light
source. When viewing an object through the night vision scope, you are
actually seeing an image that comes from the intensifier tube within the
device.
The objective lens captures the light and directs it to the front of the
intensifier tube, which is the electro-optical component. The power source
then passes energy through the intensifier tube causing electrons to strike
the phosphor screen.The image in the intensifier tube is then magnified by
the eyepiece.
This device is excellent for wildlife viewing, search and rescue opera-
tions, boating safety, home security, and camping.
Note: Battery condition will effect use and abilities.
Tube Screen Appearance
Light and dark spots caused by image con-
verter tube may be visible in the field of view.
These are normal and not considered imperfec-
tions by image intensifier standards. Most of the
distortion will occur in the peripheral area, not in
the center.

Maintenance
1. Clean the lenses only with professional lens cleaning products.
Never wipe dirt or dust off the lenses. You may use dry, compressed
air.
2. Clean the housing with a dry, soft cloth.
3. Remove battery when storing for more than two weeks.
4. Avoid storing the Goggles where sudden changes of tempera-
ture occur. Store in a dry, well ventilated area. Never store near a
heater, air conditioner, or in direct sunlight.
5. Protect the unit from moisture, dust, and sunlight. When not in
use, this product should be stored in a dry location to inhibit rust. If
this unit is used in a cold environment and then brought into a warm
area or if condensation is visible on the unit, wait five hours before
using it again, to prevent damage to the internal components of this
unit.
6. Service and repairs should only be performed by a qualified tech-
nician.
Troubleshooting
1. If the screen will not glow while in the “on” position:
Check the battery. Make sure it is charged and installed properly.
2. If the image fades or disappears completely:
a. If you are in complete darkness, the Goggles need some light.
Activate the Illuminator (7).
b. It is also possible that you pointed the device at an intense light
source which might have shut down the unit to protect the intensi-
fier tube. Turn the power off by pressing the Green Power Button
(6) and wait five minutes before turning it back on.
3. If unable to properly focus:
Try adjusting the focus on both the Eyepiece (a) and the objective lens
on the front of the Goggles (1). Also, try cleaning the lens with profes-
sional supplies.
