Precaution, Unit flashes | Newcon Optik Night Vision Scope, MB-3

Warning!

After transportation or keeping the device at temperature lower than

-25°C (-13°F), the device must be warmed up to ambient temperature, from -20°C (-4°F) to +40°C (104°F) during 2-3 hours.

Precaution

MB-3 is a 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.

•Cleaning of optical surfaces is possible only with professional camera lens cleaning supplies.

•To clean the exterior of the device, use only 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;

•The resolving power (resolution) may change in the direction from the center towards the perimeter of the field of view. This is an inherent feature of the image tube type utilized in the device. We would recommend to place the scene of observation in the center of the field of view.

If the view still does not seem in focus, clean the lenses; they could be foggy or dusty.

Unit flashes

It is normal for the unit to flash within the first 2 minutes of activation. If the flashing continues afterwards the following is a possible cause: bright environment (even with the cap closed!)

Condensation accumulates on the parts.

It is O.K. to use the scope in cold. However, when the unit is brought from the cold into a warm environment, it has to warm up for up to 5 hours (not minutes!). Only then it is allowed to turn it ON again.

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 image should be restored in within 2 minutes.

Poor atmospheric conditions such as fog, haze or extremely dark environments, will decrease the visibility distance of the unit.
