1. OVERVIEW NVS 14 (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 2+ or 3 image intensifier tube, which amplifies low light, such as moonlight, starlight or man-made light. 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.
• • • • • Flip/flop mechanism provides for unobstructed vision when the Unit is mounted on head gear or helmet Optional bridge allows combining two monocular units into a binocular instrument Waterproof design (2 meter deep immersion for 2 hours) Soft rubber eyecup makes viewing comfortable Unit can be connected to photo or video camera Please read all the instructions carefully before using. Manufacturer reserves the right to introduce minor design changes without notice.

5. IMAGE INTENSIFIER TUBE SPECIFICATIONS The Unit utilizes a small size inverting image intensifier with direct image transfer. The tube contains a microchannel plate, multi-alkaline metal S-25 (NC tube type) or GaAs (N3 tube type) photocathode, yellow-green screen and built-in electronic high voltage DC to DC converter. The input window is made of flat surface glass. The output window is a concave fibre optics element with 180° image rotation.

6. OPERATION INSTRUCTIONS 6.1 Installing battery Unit is supplied with battery not installed. Prior to installing the battery, make sure the switch (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 provides approximately twice longer battery life and better performance at low temperatures. To install battery unscrew the battery compartment cover (6). When using CR-123 Lithium type battery, remove the battery type adapter.
In daytime with lens cup on it is normal to observe a fuzzy image. Switching on night vision device in daytime is intended for testing purposes only. The rotating switch has four positions: “Off”, “Auto”, “On”, “IR”. In Auto mode the monocular will turn off automatically FIGURE 2 in the upright position. This mode saves battery IR illuminator indicator (red, life and allows avoiding left), Low battery indicator greenish shadow on the (yellow, right, optional) face, which may disclose the user.
the eyepiece screen focusing the eyepiece lens (4, Fig. 1) and then the objective lens (3, Fig. 1). 6.5 Focusing To obtain sharp image on other distance adjust the lens focus (3, Fig. 1) leaving 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.
6.7 Using the Unit with head gear or helmet The Unit is supplied with head gear (5, Fig. 1). Prior to using head gear adjust its straps so that the head gear fits head comfortably but firmly and does not slide when you are moving. The Unit is attached to the head gear with a swing arm mount (1, Fig. 3). To attach the arm mount to the head gear loosen the tightening screw (8, Fig. 1) on head gear, slide helmet groove (2, 6 Technical drawing of US clip mount 1 2 3 5 4 FIGURE 3 1. “Swing arm” mount 4.
To set comfortable eye-relief (the distance between your eye and the eyepiece), loosen tightening screw (8, Fig. 1) on the head gear and move the unit, then tighten the locking screw. To use the Unit with PASGT head and helmet mount unscrew the grooved pad (2, Fig. 3) from the swing arm mount and screw on the US type clip (6, Fig. 3) instead using four screws (Fig. 3). US type helmet clip is optional and must be ordered specially. To switch between left and right eye, press the flip button (5, Fig.
6.10 Installation of add-on lenses. Always make sure that the monocular is switched off when you put on or pull off the add-on lens. FIGURE 4 NVS 14 with attached 5x lens Note: The following procedure is identical for 3x or 5x lenses (or any other add-on lenses). Turn off the monocular. Remove the rubber lens cap. Put the lens on top of the monocular and press it firmly towards the eyepiece. Do not apply excessive pressure. Make sure that the lens is fixed well on the monocular.
The adapter (Fig. 5) consists of 2 rings: a) Camera adapter is 52x1 mm. It fits the filter lens thread of various cameras, e.g. Nikon. b) Video adapter is 37x1mm. It fits Sony cameras and some others. If our adapter does not fit your camera obtain a proper step up / step down rings. FIGURE 5 Camera / Video adapter 6.12 Demist shield and sacrificial window Note: Demist Shield and Sacrificial Window are optional.
The unit is fixed to the mount by a locking screw (1) (Fig. 6). To adjust the position of the Unit to your eye level use the screw (4). To adjust the eye relief first loosen locking screw (1) 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.
Unit until you hear a click. All other operations with the Unit mounted on a helmet are identical to those with the head gear. 6.14 Mounting on a rifle The Unit can be mounted on a rifle with Picatinny (MIL-STD1913) mount adapter. The optical axle of the monocular coincides with the rifle’s Picatinny rail.
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 over tightening damage. The advantages of the ‘Quick Release’ mount are: “Accu-torque” screw Latch with spring FIGURE 8 Quick Release adapter Quick removal and installation of the device; ‘Fool proof’ construction; Increased reliability.
6.15 Binocular configuration Two Units can be combined to form a two-eye construction with the help of an optional bridge. Lens can be attached to form a binocular optical system. To form a double-unit system use the dove tail platform (10, Fig.1) located on both sides of the Unit. These platforms are identical. The tightening screw (8) locks monoculars to the bridge. You can use the double-eye construction in a goggle (mounted on a head gear) or hand held configuration.
7. TROUBLESHOOTING 7.1 The device does not switch ON Check if the battery is properly installed. Check the battery charge. Replace battery if necessary. 7.2 Image is unclear Check if the lenses are foggy or dusty. Clean if necessary. If the image is still not focused – adjust eyepieces; see 6.4 and 6.5 for details. 7.3 Image flashes Image may flash during the first two minutes after activation. It may continue flashing if exposed to too much light (even with the lens caps on!) 7.
