IMPORTANT INFORMATION
Read prior to activation.
You have purchased a sophisticated electronic device. To
operate it properly, please read this manual carefully.
Ignoring the operation procedures described in this manual
will void your warranty.
NEVER disassemble the Unit. This device contains a source
of high voltage, which may be hazardous to your health.
NEVER open the objective lens of an active Unit in bright
light, including daylight. In the daytime the objective lens
must be covered by the lens cap provided. The tiny hole in
the cap provides enough light for daytime testing.
NEVER aim an active Unit at intense light sources, such as
lights, headlamps, campfires, the moon, etc.
NEVER reverse the polarity of a battery.
NEVER connect the Unit to any external power supplies.
ALWAYS remove battery when not in use for extended
period.
ALWAYS keep the objective lenses covered when not in use.

Precautions
All NVS 7 series devices are sophisticated precise electro-optical
instruments. It should be handled with due care:
Each Unit contains fragile components. Avoid hard impacts,
dust, moisture and abrupt changes of temperature.
Do not touch the optical surfaces other than for cleaning with
an appropriate lens cleaning kit. Doing so may damage the
anti-reflective coating.
Clean optical surfaces with professional lens cleaning
supplies.
Use only a soft clean cloth to clean the exterior of the device.
Keep the device away from sources of heat, such as heating
appliances, sunlight or central heating.
Switch off the Unit and remove the battery during extended
periods of non-operation.
Do not apply excessive force or pressure to the lens assembly,
movable parts or threaded connections.
Small dark and/or light spots may be seen in the field of view
due to considerable optical magnification of the eyepiece.
This does not affect the operational capabilities of the device.

1. OVERVIEW
Your NVS 7 series device (the “Unit”) is an optoelectronic
goggle intended for observation of objects and orientation at
night or under dark conditions. The Unit is equipped with an
advanced Generation 3 (“Gen 3”) image intensifier tube (“IIT”),
which amplifies low light, such as moonlight, starlight or man-
made light and converts it into a clear visible image.
3x, 4x, 5x and 8x add-on lenses can be attached to the Unit to
increase system magnification for use as binoculars.
In its 1x configuration, the Unit can be mounted on a combat
helmet or head harness.
Some typical activities where NVS 7 series devices can be
useful:
Law enforcement
Wildlife observation
Security
Search and rescue
Hunting (where permitted by law)
Features
Built-in infrared illuminator allows observation in total
darkness (i.e. cave or dark room);
Helmet mount (optional) allows for effective combat
operations;
Flip-up mechanism allows for unobstructed vision when
the Unit is mounted on headgear or helmet;
4
Waterproof design (standard 1 meter immersion for 30
minutes, other waterproofing options available);
Soft rubber eyecup makes viewing comfortable.
Please read all the instructions carefully prior to using the Unit.
Manufacturer reserves the right to introduce minor design
changes without notice.
