Precautions
6. TROUBLESHOOTING
The device does not work.
Check that the battery is installed properly.
Check the charge of the batteries. Replace them if they are weak.
NVS 7 is a sophisticated precise optical instrument equipped
with electronics.
Therefore, it should be handled with due care.
•
Try to avoid strong heat, direct sunlight, impacts, dust, moisture
and sudden changes of temperatures. Keep in mind that, although
being very durable, NVS7 contains fragile components.
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 Image Intensifier Tube
coating in the form of dark and/or white points may be seen
in the field of view. This does not affect the serviceability of
the device.
The image does not appear in focus.
Bring the inspected object to the center of the image. Rotate the
eyepieces (6) 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.
Visibility decreases and / or disappears.
Bright light sources (moon, projectors or headlights) may cause
visibility to degrade or even completely disappear. Move the
device 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.
Press the button (2) to change the fixating point of the goggles
during operation. Rotate the goggles with depressed button (2)
until you hear the click. You can raise the unit up vertically for
unobstructed vision without taking the helmet off. The unit will
automatically shut off in this position. (Note: this is an optional
feature). Reverse the operation to turn it on.
1. OVERVIEW
The NVS 7 type night vision is observational optico-electronic
binoculars/goggles, intended for examining objects and orientation at
nighttime or dark conditions. The unit utilizes a generation 2+ or 3
image intensifier tube, which amplifies available moonlight, starlight or
man-made light. The device was designed to be easy to use, and
provide many years of operation.
All other operations with goggles mounted on a helmet are identical
to those with the head gear.
Some of the typical activities where NVS 7 will be useful:
•
•
•
•
•
•
Law enforcement
Wildlife observation
Security
Search and rescue
Hunting
Photography (Dark room operation)
Features
•
•
Waterproof construction
Built-in infrared illuminator allows observations in total
darkness (i.e. basement, cave or dark room);
Flip/flop mechanism allows easy unobstructed vision;
Independently adjustable eyepieces;
Ideal in situations requiring hands-free operation;
Lightweight and comfortable;
•
•
•
•
•
A soft rubberized eyepiece makes the viewing more
comfortable.
WARNING! NEVER OPERATE YOUR NIGHT VISION
DEVICE IN DAYLIGHT WITHOUT THE LENS COVER ON!
NEVER DIRECT THE LENS IN THE DIRECTION OF
BRIGHT LIGHT!
2. COMPONENTS
NVS 7 is supplied with the following components:
5.5 Using the helmet mount (optional)
NVS 7 can be equipped with an optional helmet mount. This
mount is customized for a particular type within the wide variety
of existing helmet models. The mount is attached to a helmet
with stripes. The goggles are fixed to the mount by a locking
screw (1). Adjust the goggles position on your eye level with the
screw (4).Then adjust the
eye-relief (the distance
between your eyes and the
eyepieces), which should be

During daytime: It is allowed to turn on the goggles at daytime for a
short period of time, for testing purposes only. Lens cap must be
installed during this operation. The image will be fuzzy, and/or you will
see 3 images. This is normal because of the catadioptric construction of
the lens.

During night time: Remove the lens cap by unscrewing it counter
clockwise. Keep the lens cap in a safe place, so it won't get lost. Use
the focusing ring at the base of the lens in order to adjust the image.
You will need to readjust the image for different objects at different
distances.. You should expect to have a sharp image for distances as
close as 10-20m through infinity.

Warning: The lens should screw in smoothly. If not, remove it and
make sure that the threads are matching correctly.
Failing to do so and forcing the installation of the lens will
result in broken threads and costly repairs to both the

You can use the device with the head gear or without it.
When used with the head gear, first adjust all the straps for
individual head size. Take off the lens covers (6) from the lens
(7). Turn on the device-using switch (1). 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 I/R switch
(1). The red indicator (Fig. 3) will be on.
Note: The I/R illuminator is visible to anybody with a night
vision device and will disclose the user’s presence.
You can raise the unit up for unobstructed vision without taking
the head gear off by using the “flip/flop” feature (Fig. 2). To
switch the unit into off-working position: press the lever (9)
down and raise the device into vertical position, until you hear a
click. The unit automatically shuts off in the upright position
(Note: this is an optional feature).

After operation the user should turn off the unit by rotating switch (1)
to the OFF position. Put protective lens caps (6) on the lens (7). After
operation remove the batteries from the battery compartment to avoid
any damage of the device in case of occasional leakage of electrolyte
from the batteries.

5. OPERATION INSTRUCTIONS
5.1 Pre-starting procedures:
5.2 Testing of operation:
When wearing the unit the eye-relief (the distance between your
eyes and the eyepieces) should be 15-22 mm. In order to achieve
this, loosen locking screw (8) and set a comfortable distance
between the eyes and the eyepieces; then rotate the locking
screw (8) back. Turn on the device by rotating the switch (1) to
the ON position. The green screens of the scopes must be lit.
Direct the device on an object placed within 8-15m from the
viewer. Rotate the eyepieces (4) and the lens (7) in order to
achieve the sharpest image on the screen of the image tube.
The eyepieces (4) are set for a person individual eye sight, and
do not need to be changed if the same person is using the
apparatus. The lens (7) focus needs to be adjusted according to a
different distance of observed scenery.
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 (6) 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.
There are one or two indicators
in the visible zone (see Fig. 3).
When they are off the user can
hardly notice them. Bright
