PECULIARITIES OF USE
Your night vision device is designed to provide many years of reliable service.To ensure high performance you
should adhere to the following rules:
• Do not direct the unit in the “on” position at intense sources of light, such as a car’s headlights or burning re.
This may disable the unit for an unknown length of time or cause a dark spot in the center of the eld of view.
Do not turn the unit on in daylight without the protective cap rmly secured over the objective lens, as this may
damage the unit.
• Any such damage may void the warranty.
• Never leave the unit in the “on” position over an extended length of time in an area with a light level exceeding
1-10 lux (twilight - 1lux, deep twilight - .001 lux). Please keep the protective cap on the objective under greater
light level.
• Your device was designed to be self-contained. Do not open the body of the unit or otherwise attempt to
service this device. If such need arises return the unit for replacement or repair.

• Direct your device at an object at a distance of approximately 100m. Adjust the eyepiece and objective lens
diopter setting to focus the unit by rotating the eyepiece (4) and objective lens (5).

BATTERY INSTALLATION
Your device runs on two AA batteries. To install, slide back the battery compartment cover, insert the
batteries into the battery compartment so that the positive (+) and negative (-) terminals of the batteries
match the markings inside the compartment, close the battery cover carefully.
6
CAUTION!
Your device can be used in extreme cold. However, when the unit is brought back into a warm environment, please
wait for about 2-3 hours before using the unit again. Failure to do so may result in damage as a result of condensation
accumulating on the internal circuitry of the unit.
MAINTENANCE
• Clean the lens with professional lens cleaning supplies intended for use with multi-coated optics.
• Blow any dust or dirt off the lenses using dry, compressed air.
• Clean the unit housing with petroleum jelly applied by a soft, clean cloth.
STORAGE
Always store the unit in its case in a dry, well-ventilated area away from heating/air conditioning vents (or other heating
devices). Remove the batteries if the device is to be stored for longer than two months.
TROUBLESHOOTING
The unit will not turn on.
Check that the batteries are installed properly. Check the battery contacts to ensure they are clean and free of
corrosion. Make sure that the external contact lugs are not broken. If necessary, replace the batteries. Also, be sure
that the power is in the “ON” position when trying to turn on the unit.

Distinct black dots appear on the screen.
These dots are minor cosmetic blemishes resulting from tube production processes and do not interfere with the
reliability or performance of the unit.
The unit ickers, ashes or “snows”.
The unit may icker or ash when used in a bright environment; to correct this, place the cap over the objective
lens and enter a dark environment. The unit will restore itself to a natural fuctioning state in several minutes or hours,
depending on how long the unit was exposed to the light.
The unit may icker for the rst several seconds of use, even when in a dark environment, before the unit corrects
itself and funtions properly.
The unit may “snow” for several minutes after being exposed to a bright light source (daylight, car’s headlights, re, ect.)
even if being operated in complete darkness.
The image is not focused.
Adjust the focus of the eyepiece and the objective (see “Use and Testing” section). Check that the lenses are not foggy
or dusty; if they are, carefully clean the external surfaces of lenses with a soft cotton fabric. Replace the batteries if the
total battery charge is less than 2.2V.
When the unit is brought into a warm environment from a cold one, condensation may appear on the internal lenses;
you must wait two hours before using the unit.
