THANK YOU FOR PURCHASING THE NVS 7

TYPE NIGHT VISION

BINOCULARS/GOGGLES. PLEASE DEMAND

TO CHECK THE DEVICE FOR PROPER

OPERATION WHEN BUYING IT. PLEASE

READ ALL THE INSTRUCTIONS

CAREFULLY BEFORE USE.

Precautions

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.

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.

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.

All other operations with goggles mounted on a helmet are identical

to those with the head gear.

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.

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!

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

about 25 mm. In order to

achieve this, loosen locking

screw (1) and set a

comfortable distance

between the eyes and the

eyepieces; then tighten the

locking screw back.

You can fixate the unit in

three predetermined

positions: vertical,

horizontal, and 15-20

degrees above horizontal.

The angles between these

positions cannot be changed,

but the starting point is adjusted by screws (3). If you loosen

them, you can rotate the flip-flop mechanism to find the most

suitable starting fixating point. Don’t forget to tighten the screws

(3) after adjustment.

OPERATION:

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.

Warning. Never turn on the goggles with either 1x or 4x lens

during daytime, without the lens caps. Doing so will result in

damaged power supply and/or tube and costly repairs not

covered by the warranty.

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.

5.4 Installation and operation of optional lenses

INSTALLATION:

Note: The following procedure is identical for 4x or 8x lenses . Unpack

the 4x lens from the box. Turn off the NVS 7 goggles. Remove the

rubber lens cap (6). Remove (unscrew) the original 1x lens, which is

included with the NVS 7 goggles. To do that, hold the lens at its base

(1) and unscrew it counters clock wise. Once the original 1x lens has

been removed, store it in a safe, clean space (you can use the 4x lens

packaging for that). The

NVS 7 4x lens should be

screwed, clock wise,

instead of the 1x original

lens. Please exercise

extreme caution at the

initial stage.

The threads are very fine

(to prevent humidity

penetration) and can be

damaged easily. Do not

force the lens rotation. If it

does not screw in

smoothly, remove it and

make sure that the threads are matching correctly. Now it is ready for

operation. Removal of the lens is done in reverse order.

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

goggles and the 4x lens.

5.3 Operation at night

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).

Reverse the operation for a working position.

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:

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

yellow and/or flashing red

indicates that battery voltage

goes low. You should have the

fresh batteries ready and

replace them in time. Bright

red reminds / warns the user

that the I/R illuminator is on

(see below).

If everything works, now is a

great time to fill the warranty

card.

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.

The distance between the eyes should be automatically

applicable for people with 58-72 mm interpupilary distance,

which covers over 99% of the adult population.
