NV66 – G2  
105 Sparks Ave., Toronto, ON, M2H 2S5, Canada  
 
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.

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.
