Operation Instructions Warning, Precautions

6.OPERATION INSTRUCTIONS WARNING!

NEVER OPERATE YOUR NIGHT VISION DEVICE IN DAYLIGHT AREAS WITHOUT THE LENS COVERS ON! NEVER DIRECT THE LENS IN THE DIRECTION OF BRIGHT LIGHT!

Pre-starting procedures.

6.1Unpack the device. In order to install the battery, first open the battery house cover (2), and install the battery. Observe the correct polarity indicated on the housing. Close the battery house cover.

6.2Check the functioning of the device by switching it on (push and hold button 4) and looking through eye-pieces (5). (Make sure the lens caps are on while operating during the day). If power supply and the batteries are O.K., you will see greenish lit screen. If the screen is not lit, check the batteries. Replace the battery if necessary. If everything works, now is a great time to fill the warranty card.

Note: The unit will remain on for up to several minutes after switching the power off. This is normal.

Testing of operation:

Direct the device on an object placed within 8-15m from the viewer. Turning the eye-pieces (5) try to achieve the sharpest image on the screen of the image tube. Adjust the distance between the eyes by folding the binoculars until 2 images will merge into 1.

Warning! After transportation or keeping the device at temperature lower than -25°C (-13°F), the device must be warmed up to ambient temperature for at least 2 hours.

Precautions

BN-5 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.

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

•Do not touch optical surface with fingers. Doing so may damage the anti-reflection coating.

•To clean the exterior of the device, use only a soft clean cloth.

•Do not take the covers off the lenses 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.
