General information on Night Vision devices.

This electro-optical device assists in viewing in near darkness or complete darkness. It works by amplifying
the already existing light of 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 9 volt 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 operations, surveillance, boating
safety, home security, and camping.

Important Precautions

1. Never turn on the scope or take off the lens cover in daylight or under bright illumination such as
automobile headlights.

2. Do not try to service the unit yourself. Take it to a qualified service technician.

3. Protect the unit from moisture, dust, and sunlight. If condensation is visible on the unit, wait five
hours before using it again.

4. Avoid storing the scope where sudden changes of temperature occur. Keep it away from air
conditioning or heating vents.

Tube Screen Appearance

Light and dark spots caused
by image converter tube may
be visible in the field of view.
These are normal and not considered
imperfections by Image Intensifier
Standards. Most of the distortion
will occur in the peripheral area,
not in the center.

. .

Maintenance

1. Always clean lens with professional supplies. Never wipe dirt or dust off the lens. You may use
dry, compressed air.

2. Clean the housing with a dry, soft cloth.

3. Store in a dry, well ventilated area. Never store near a heater, air conditioner, or in direct
sunlight.

4. Remove battery when storing for more than two weeks.

Troubleshooting

1. The screen will not glow while in the on position: Check battery. Make sure it is charged and
installed properly.

2. The image fades or disappears completely: If you are in complete darkness, the scope needs
some light. Activate the Illuminator (#6). It is possible that you pointed the device at an intense light
source which might have shut down the unit to protect the intensifier tube. Turn the power off and wait five
minutes before turning it back on.

3. Unable to properly focus: Try adjusting the focus on both the Eyepiece (#1) and the
Objective Lens Ring (#4) Also, try cleaning the lens with professional supplies.
