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 cap. A 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 a long

period.

 ALWAYS keep the objective lenses covered when not

in use.

 ALWAYS store the device in a warm dry place.

ii

PRECAUTIONS

NV66-G2 is a sophisticated precise optical instrument
equipped with electronics. It should be handled with due
care:

 Unit contains fragile components. Avoid impacts,

dust, moisture and sharp changes of temperature.

 Do not touch the optical surfaces other than for

cleaning. Doing so may damage the anti-reflection
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 the

extended periods of non-operation.

 Do not apply an excessive force or pressure to the lens

assembly, movable parts and thread 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

5. OPERATION INSTRUCTIONS

5.1 Installing battery

Unpack the device. Unit is supplied with battery not
installed.

Prior to installing the battery, make sure the switch

(1, Fig.1) is in the OFF position and the lens cap is on.

Unscrew the battery compartment cover (5, Fig.1), and
install 2 fresh AA batteries. Observe the correct polarity
indicated on the housing. Screw in the battery
compartment cover back.

5.2 Switching the unit on

In daylight put on the lens cap prior to switching

the unit on.

To check if the unit is operational switch it ON (rotate
switch (1, Fig.1) clockwise) and look through eyepiece (4,
Fig.1). You should see greenish-lit screen. If the screen is
not lit check the battery.

10

Fig.3 Low battery indicator

When the unit is ON user may see a circular indicator
through the eyepiece (Fig. 3). It is hardly noticeable when
not active.

Flashing indicates low battery. For uninterrupted
operation keep fresh batteries ready and replace them on
time.

Solid red dot indicates that the IR illuminator is on.

In the daytime with lens cap on it is normal to observe a
fuzzy image. Switching on the unit device in the daytime
is intended for testing purposes only.

5.3 Switching the unit off

After you have finished using the device, turn it off by
rotating switch (1, Fig.1) to OFF position. Put protective
lens cap on the lens. Remove the battery from the battery
compartment to avoid damaging of the device in case of
electrolyte leakage.

11

5.4 Operating at night

Take off the lens cover (6, Fig.1) from the lens (7, Fig.1).
Turn on the device using switch (1, Fig.1). If lighting is
insufficient, turn on the IR illuminator by turning switch
(1, Fig.1). The red indicator (Fig. 3) will go on. IR
illuminator is effective when observing an object located
not far from the viewer.

The IR illuminator is visible to anybody

with a night vision device.

You can raise the unit up for unobstructed vision without
taking the headgear off by using the “flip/flop” feature
(Fig. 2). To do so: press the lever (9) and raise the device
into vertical position, until you hear a click.

Reverse the operation for a working position.

5.5 Adjusting to individual vision

Turn on the device. Direct the device at an object placed
within 8-15 m from the viewer. Obtain the sharpest image
possible on the eyepiece screen by focusing the eyepiece
lens (3) and then the objective lens (7, Fig.2).

12

5.6 Focusing

To obtain sharp image at other distance adjust the lens
focus (7, Fig.1) leaving eyepiece setting intact. You
should be able to obtain a sharp image for distances from

0.2-10 m to infinity depending on lens magnification.

5.7 Using Unit with headgear

Prior to using the unit with the headgear adjust all the
straps to the head size.

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 the locking screw
(8, Fig.1) and set a comfortable distance between the eyes
and the eyepieces; then tighten the locking screw
(8, Fig.1).

5.8 Interpupillary distance

The unit is designed to accommodate interpupillary
distance of 58-72 mm without any additional adjustment
and should be comfortable for 99% of adults.

13

5.9 Installation of interchangeable lenses

Do not apply an excessive force when

changing the lenses.

The following procedure is identical for 1x, 4x, 5x or 8x
lenses.

1. Make sure the unit is off.

2. Remove the lens cap (6, Fig.1).

3. Detach the current lens: hold the lens by its base

(1, Fig.1) and rotate it counter-clockwise. Once
the lens has been removed, store it in a safe,
clean space.

4. Screw in (clockwise) new lens.

The threads are very fine (to prevent humidity
penetration) and can be damaged easily. Do not apply
force to the lens rotation. If lens does not screw in
smoothly make sure that the threads match.

Unit is ready for operation immediately after the lens
change.

Warning: Forcing installation of the lens may damage
the thread and cause costly repairs to both the goggles

and the lens that are not covered by warranty.

The unit can be equipped with an optional helmet mount.
This mount can be customized to fit a variety of existing
helmet models.

The mount is attached to a helmet with straps.

16

The unit is fixed to the mount by a locking screw (1, Fig.

7). To adjust the position of the unit to your eye level, use
the screw (4, Fig. 7). To adjust the eye relief first loosen
locking screw (1, Fig. 7) and set a comfortable distance
between the eyes and the eyepiece; then tighten the
locking screw back.

You can fixate the unit in three predetermined positions:
vertical, horizontal, and 15-20 degrees above horizontal.
Although the relative angles between these positions
cannot be changed, the starting point can be adjusted by
screws (3, Fig. 7). If you loosen them, you can rotate the
flip-flop mechanism to find the suitable starting point.
Tighten the screws (3, Fig. 7) after the adjustment.

You can raise the unit for unobstructed view without
taking the helmet off. To do so press (and hold) the button
(2, Fig. 7) and rotate the unit until you hear a click.

All other operations with the unit mounted on a helmet
are identical to those with the headgear.

6. TROUBLESHOOTING

6.1 No green light through eyepieces

Check that the batteries are installed properly.

Check the charge of the batteries. Replace them if they
are weak.

6.2 Image is unclear

Check if the lenses are foggy or dusty. Clean them if
necessary.
If the image is still unfocused – adjust the eyepieces; see
chapter 5 for details.

6.3 Image flashes

Image may flash during the first two minutes after
activation. It may continue flashing if exposed to bright
light (even with the lens cap on!).

6.4 Condensation accumulates on the parts

When the unit is brought from the cold into a warm
environment internal condensation may appear. The unit
has to be warmed up for up to two hours to regain full
operational capacity.

18

6.5 Visibility decreased or disappeared

Bright light sources (the Moon, projectors or headlights)
may cause visibility to degrade or even completely
disappear. Move the device away from the light source
immediately. The image will be restored within two
minutes.

Adverse atmospheric conditions such as fog, haze or
extremely dark environments will decrease visibility.
