Precautions  
NV66-G2-4x 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  
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.  
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.  
When the unit is ON user may see a  
circular indicator through the  
eyepiece (Fig. 2). It is hardly  
noticeable when not active.  
Flashing indicates low battery. For  
uninterrupted operation keep fresh  
batteries ready and replace them on  
time.  
FIGURE 2  
Low battery indicator  
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.  
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.  
Operating at night  
Take off the lens cover from the lens. 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. 2) 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.  
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 and then the  
objective lens.  
Focusing  
To obtain sharp image at other distance adjust the lens focus  
leaving eyepiece setting intact. You should be able to obtain a  
sharp image for distances from 2-10 m to infinity.

Interpupillary distance  
The unit is designed to accommodate interpupillary distance of  
57-73 mm without any additional adjustment and should be  
comfortable for 99% of adults.  
Installation of interchangeable lenses  
Do not apply an excessive force when changing the lenses.  
1. Make sure the unit is off.  
2. Remove the lens cap  
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  
binoculars and the lens that are not covered by  
warranty.

6. TROUBLESHOOTING  
No green light through eyepieces  
Check that the batteries are installed properly.  
Check the charge of the batteries. Replace them if they are weak.  
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 5.5 and  
5.6 for details.  
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!).  
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.  
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.
