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.

• Protect the device from exposure to direct sunlight and extreme temperatures.

• Avoid dropping the unit. The device incorporates a sophisticated optical system which could be damaged in
extreme cases of misues.

• Clean optical parts (lenses) with professional lens cleaning supplies designed for use with multi-coated optics.

USE AND TESTING

Make sure the batteries have been installed according to instructions found in the battery installation section of this manual.

• Enter a dark area before turning on the device.

• Remove the objective cap (1).

• Activate the device by pushing the “ON” button (3). The green LED (6) will light up.

• You can test your device in a light area without removing the protective cap. This will not damage your unit.

• If the subject to be viewed is in a completely dark area, including lowlight shadow areas; activate the infrared
illuminator by pressing the “IR” button (2). The LED will light up red.

• 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).

• After the adjustment, do not rotate the eyepiece irrespective of the distance and other conditions.

• Direct your device at the subject to be viewed and adjust the nal focus by rotating the objective lens (5)

focusing ring until the image quality is optimal.

• When you are nished using the device, turn the unit off pushing the “ON” (3) button. Put the cap back on the

objective lens and place the unit in the carrying case.

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.

7

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.

8

Visibility decreases or disappears.

Bright light sources, such as headlights, may cause visibility to decrease or disappear and the image to icker.
Turn the power off and turn the scope away from the light source; visibility will restore itself in several minutes.
