1. OVERVIEW NVS 14-3GCS (the unit) is an optoelectronic monocular, intended for observation of objects and orientation at night or under dark conditions. The unit is equipped with a generation 3 image intensifier tube, which amplifies low light, such as moonlight, starlight or man-made light. The unit is waterproof to the depth of 20 meters. An add-on lens can be attached to the unit to increase magnification. Two units can be combined to form a two-eye optical system with the help of an optional bridge.
Optional helmet mount allows combatant operations Optional weapon mount allows night shooting or also be used in conjunction with halosight Optional bridge allows combining two monoculars into a binocular configuration Supreme waterproof design (20 meter deep immersion for 30 minutes) Soft rubber eyecup makes viewing comfortable Unit can be connected to photo or video camera Please read all the instructions carefully before using it.

6. OPERATION INSTRUCTIONS 6.1 Installing battery Unit is supplied with uninstalled battery. Prior to installing the battery, make sure the switch (1, Fig.1) is in the OFF position and the lens cap is on. The unit can operate on either AA Alkaline or CR-123 Lithium battery. Lithium battery durability is doubled against the service time of conventional battery and provides better performance at low temperatures. To install battery unscrew the battery compartment cover (6, Fig.1).
battery ready and replace it on time. Bright red indicator reminds the user that the IR illuminator is on (for more details on illuminator see 6.9). In the daytime with lens cap on it is normal to observe a fuzzy image. Switching on the night vision device in the daytime is intended for testing purposes only. The rotating switch has four positions: “Off”, “Auto”, “On”, FIGURE 2 “IR”. In Auto mode the monocular will switch off automatically when IR illuminator indicator (red, turned upright.
6.5 Focusing To obtain a sharp image at some other distances adjust the lens focus (3, Fig. 1) leaving the eyepiece setting intact. You should be able to obtain a sharp image for distances from 2-10m to infinity. If you wear eyeglasses or NBC protective mask, you may like to fold the rubber eyecup. 6.6 Manual gain adjustment NVS 14-3GCS monocular is equipped with the manual gain adjustment handle.

This sensor shuts the monocular off after about 45 second exposure to light exceeding 10-1 lux. To reset the monocular switch it off and then back on as described in 6.3 and 6.2. High-light shut-off feature does not mean that the unit will react to occasional flashes or bright spots.
FIGURE 3 1. “Swing arm” mount 4. 2. Grooved pad 5. Unit groove Flip button 3. Locking knob 6. US clip mount The unit is attached to the headgear with a swing arm mount (1, Fig. 3). To attach the arm mount to the headgear loosen the tightening screw (8, Fig. 1) on headgear, slide helmet groove (2, Fig. 3) onto the rail, and then tighten the screw. To attach monocular to the arm turn the knob (3, Fig. 3), slide the arm groove (4, Fig.3) along the dovetail platform of the monocular (10, Fig.
In “Auto” position of the switch, the monocular will turn off automatically. Reverse the operation to return the unit to working position. 6.10 Using IR illuminator In case of insufficient light when observing a close object turn on the IR illuminator by turning the switch (1, Fig.1). Red indicator visible through the eyepiece will warn you when the IR illuminator is on. Note: The IR illuminator is visible to anybody equipped with a night vision device and can disclose the user’s presence. 6.
(or any other add-on lenses). Turn off the monocular. Remove the lens cap. Press the lens firmly towards the eyepiece. Do not apply excessive pressure. Make sure that the lens is fixed well on the monocular. To return the monocular back to 1x magnification, pull off the lens. 6.12 Demist shield and sacrificial window Note: Demist Shield and Sacrificial Window are optional. Sacrificial window protects the objective lens from the abrasive influence of sand and dust in the night time.
6.14 Using the helmet mount The unit can be equipped with an optional helmet mount. This mount can be customized to fit a wide range of existing helmet models. The mount is attached to a helmet with straps. 1 2 3 4 FIGURE 6. Helmet mount 1. Locking screw 3. Flip-flop adjusting screws 2. Flip/flop button 4. Mount binding screw The unit is fixed to the mount by the locking screw (1, Fig. 6). To adjust the position of the unit to your eye level use the screw (4, Fig. 6).
relative angles between these positions cannot be changed, the starting point can be adjusted by screws (3, Fig.6). If you loosen them, you can rotate the flip-flop mechanism to find the suitable starting point. Tighten the screws (3, Fig.6) 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.6) and rotate the unit until you hear a click.
The ‘Quick Release’ model (Fig. 8) utilizes a latch with a spring and patented accu-torque screw. You can attach and detach your monocular within a few seconds. The accu-torque screw fixes the mount with predefined torque thus protecting the thread from accidental damage caused by over tightening. The advantages of the ‘Quick Release’ mount are: Quick removal and installation of the device; Foolproof design; FIGURE 8 Quick Release adapter “Accu-torque” screw Latch with spring Increased reliability.
daytime scope with the help of an optional NVS Coupler. 6.17 Binocular configuration Two units can be combined into dual channel goggles/binoculars with the help of an optional bridge. Optional lens can be attached to form a binocular 3x system. To form a double-unit system use the dovetail platform (10, Fig.1) located on both sides of the unit. These platforms are identical. The tightening screw (8, Fig. 1) locks monocular to the bridge.
In the dual configuration the interpupillary distance can be adjusted between 58 and 72 mm right on a bridge.
7. TROUBLESHOOTING 7.1 No green light through eyepieces Check that the batteries are installed properly. Check the charge of the batteries. Replace them if they are weak. 7.2 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 5.5 and 5.6 for details. 7.3 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!).
