allowed to turn it ON again.  
2. OVERVIEW  
Visibility decreases and / or disappears.  
Bright light sources (moon, projectors or headlights) may  
cause visibility to degrade or even completely disappear.  
Move the scope away from the light source immediately.  
The night vision rifle scope DN-140 is an  
observational optico-electronic monocular device intended  
for precise shooting, examining distant objects orientation at  
nighttime conditions. The unit utilizes an image intensifier  
which amplifies available moonlight,

7. Next, focus the scope by turning the focus ring on the  
sight’s ring. You may have to re-focus both lenses to  
achieve sharp focus.  
NOTE: For best result, use a 50mm lens. Wide angle and/or  
zoom lenses typically cannot provide a full-screen image  
through the DN-200 unit. Camera lens aperture setting  
lower (wider) than f2.0 may result in lower image  
resolution.  
FILM: Use a ISO 400 film or faster. Also, using a tripod is  
strongly recommended due to the low shutter speeds  
common in night vision photography. The following table  
shows approximate shutter speeds at various ISO values  
with the aperture set at f1.8.  
starlight or man-made light. The scope was designed to be  
easy to use, and provide many years of operation.  
Some of the typical activities where the DN-140  
Night Vision Rifle Scope will be useful:  
law enforcement  
hunting  
search and rescue  
wildlife observation

6.3 Operation at night  
Warning!  
AT INSUFFICIENT AMBIENT  
ILLUMINATION  
At insufficient ambient illumination use the  
Infra/Red illuminator (5). Activated by rotating switch (10)  
clockwise.  
After transportation or keeping the device at temperature  
lower than -40°C (-40°F), the device must be warmed up to  
ambient temperature, from -10°C (14°F) to +40°C (104°F),  
relative humidity of 80% max. at 20°C (68°F).  
If brightness of the screen is decreasing, replace the  
batteries.  
Take out the batteries during long periods of non-  
operation.  
Precautions  
DN-140 is a sophisticated precision optical instrument  
equipped with electronics.  
Therefore, it should be handled with due care.  
Keep your device away from direct sunlight, impacts,  
dust, moisture, and sudden changes of temperatures.  
Do not touch the optical surfaces with fingers. Doing so  
may damage the anti-reflection coating.  
7. a) USING THE DN-140 WITH A CAMERA OR A  
VIDEO CAMCORDER  
1. Pull out the rubber eye-guard (3) out from the eye-piece  
(2).  
Cleaning of optical surfaces is possible only with  
professional camera lens cleaning supplies.  
To clean the exterior of the device, use a soft clean cloth.  
Do not take the cover off the lens if not necessary.  
Keep away from heating appliances and central heating.  
Make sure to switch off the unit during periods of non-  
operation and when storing the device for long period of  
time.  
Do not apply superfluous efforts at work with lens  
assembly, agile elements and thread connections.  
Due to considerable optical magnification of the eye-  
piece some small structures inside the tube coating in the  
form of dark and/or white points may be seen in the field  
of view which does not affect the serviceability of the  
device.;  
2. Thread the camera adapter (optional) onto the filter  
threads of your camera’s lens.  
The camera adapter uses a 52mm thread size; a common  
filter thread size for many Nikon, Canon and Minolta lenses.  
You may purchase a step-up/step-down ring from your local  
camera store if your lens does not use 52mm filters.  
3. Fit the other end of the Camera adapter onto the eyepiece  
socket of the scope. Lock the adapter in place by using the  
three screws.  
4. Connect the lens to the camera.  
5. Make sure that you are in a dark area and that the lens  
cap is attached, switch the unit ON.  
6. Focus the camera lens until the image is sharp.
