Newcon Optik DN140M - Manual (Page 6)

Warning!
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).
Precautions
DN-140M 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.
• Optical surfaces should be cleaned with only
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 when not in use and when
storing the device for long period of time.
• Do not apply needless effort to the lens assembly, agile
elements and thread connections.
• Due to considerable optical magnification of the eyepiece
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 performance of the device.

6.3 Operation at night
INSUFFICIENT AMBIENT ILLUMINATION
If you encounter insufficient ambient illumination, use the
Infra/Red illuminator (5). Activated by rotating switch (10)
clockwise. The illuminator beam can be focused for optimal
results, by rotating the lens.
If brightness of the screen is decreasing, replace the
batteries. Take out the batteries during long periods of non-
operation.
7. a) USING THE DN-140M WITH A CAMERA OR A
VIDEO CAMCORDER
1. Pull the rubber eye-guard (3) out from the eyepiece (2).
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.
