TROUBLESHOOTING
6.
The unit does not work.
Check that the battery is installed properly.
Check the charge of the batteries. Replace if it is weak.
The image does not appear in focus.
Bring the inspected object to the center of the image. Turning the eyepieces (6) adjust to
achieve the clearest image on the screen. Then obtain the most clear-cut image of the object
focusing the lens (2). Repeat the steps of focusing if necessary
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 caps closed!)
Condensation accumulates on the parts.
It is O.K. to use the unit in cold. However, when the unit is brought from the cold into a warm
environment, it has to warm up for up to 2 hours (not minutes!).
Only then it is allowed to turn it ON again

OVERVIEW
1.
The night vision NVS7-2/4X / NVS7-2/4XHD is observational binoculars, intended
for examining objects and orientation at nighttime or dark conditions. The unit utilizes a
generation 2+ or 3 image intensifier, which amplifies available moonlight, starlight or
made light
operation.
. The binoculars were designed to be easy to use, and provide many years of
Some of the typical activities where the binoculars will be useful:
• Law enforcement
• Wildlife observation
• Security
• Search and rescue
• Hunting
• Photography (Dark room operation)

Features
• Waterproof construction
• Built-in Infra Red illuminator allows observations in total darkness
(i.e. basement, cave or dark room);
• Independently adjustable eyepieces;
• Lightweight and comfortable;
• Soft rubberized eye pieces makes the viewing more comfortable;
After transportation or keeping the device at temperature lower than -25°C (-13°F), the device must be
warmed up to ambient temperature, from -25°C (-13°F) to +40°C (104°F),
relative humidity of 80% max. at 20°C (68°F), for at least 2 hours.
Precautions
NVS7-2/4X / NVS7-2/4XHD
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 allowed 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 and remove the batteries 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;
Warning!
is a sophisticated precision optical instrument
5.2 Operation at Night
Unscrew the lens covers from the lens. Turn on the device by turning the
switch to the on position. In case of insufficient lighting when observing an
object which is situated not far from the viewer, turn on the I/R illuminator by
turning the switch to the next setting.
Note: The illuminator will be activated only if the unit has been already
switched on by switch.
Note: When looking directly in front of the binoculars operational
illuminator appears as a red dot. The illuminator can be also detected using
night vision device. Therefore, if you need to remain undetected, use the
illuminator with caution.
If brightness of the screen is decreasing, replace the batteries. After operation the unit will
automatically turn off after few minutes, till the complete discharge of the units power. Put
protective lens caps on the lenses. This feature can be used to economically utilize the battery’s
power by periodically switching on and off the device during operation. After operation remove
the battery from the battery compartment to avoid any damage of the device in case of
occasional leakage of electrolyte from the battery.
5. OPERATION INSTRUCTIONS
WARNING! NEVER OPERATE YOUR NIGHT VISION DEVICE IN DAYLIGHT
AREAS WITHOUT THE LENS COVER ON!
NEVER DIRECT THE LENS IN THE DIRECTION
OF BRIGHT LIGHT!
5.1 Pre-starting procedures:
1. Unpack the device. In order to install the battery, first make sure the
switch (1) is in the OFF position. Unscrew the battery house cover (5), and install 2
fresh AA batteries. Observe the correct polarity indicated on the housing. Screw the
battery house cover back on. Check the functioning of the device by switching it on
(rotate switch 1) and looking through eyepieces (4). (Make sure the lens cap is on
while operating during the daytime). 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
batteries if necessary. If everything works, now is a great time to fill the warranty card.
