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.

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.
