5. OPERATION INSTRUCTIONS 5.1 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).
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”, “IR”. In Auto mode the goggles will FIGURE 2 switch off automatically when turned upright.
5.5 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. 5.6 Manual gain adjustment NVS 15 goggles is equipped with the manual gain adjustment handle.
5.7 Auto shut OFF at bright light The NVS 15 goggles has a built-in high light sensor located near the IR illuminator (2, Fig. 1). This sensor shuts the goggles off after about 45 second exposure to light exceeding 10-1 lux. To reset the goggles 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. It protects the tube against excessive light exposure only. 5.
5.9 Swinging head mounted unit for unobstructed view When the head mounted unit is not in use you can raise it to clear the view without taking the headgear off by using the “flip/flop” feature. To swing the unit from the view press the button (1, Fig. 3) and raise the device until you hear a click. In “Auto” position of the switch, the goggles will turn off automatically. Reverse the operation to return the unit to working position. 5.
5.11 Installation of add-on lenses. Always make sure that the goggles is switched off when you put on or take off the add-on lens. FIGURE 4 NVS 15 Single unit with attached 3x lens Note: The following procedure is identical for 3x or 5x lenses (or any other add-on lenses). Turn off the goggles. 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 goggles.
Demist shield filter protects the eyepiece against fogging. To install it fold the eyecup to the very bottom to get the full access to the thread, and screw the filter gently onto the eyepiece. 5.13 Using the camera / video adapter Before using the (optional) adapters, remove the rubber eyepiece carefully. The adapter (Fig. 5) consists of 2 rings: a) Camera adapter is 52x0.75mm. It fits the filter lens thread of various cameras, e.g. Nikon. FIGURE 5 b) Video adapter is 37x0.75mm.

To adjust the position of the unit to your eye level use the screw (4, Fig. 6). To adjust the eye relief first loosen the locking screw (1, Fig.6) and set a comfortable distance between the eyes and the eyepiece; then tighten the locking screw back.
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. All other operations with the unit mounted on a helmet are identical to those with the headgear. 5.15 Mounting on a rifle The unit can be mounted on a rifle with Picatinny mount adapter (MIL-STD-1913). The optical axle of the goggles coincides with the rifle’s Picatinny rail. FIGURE 7. NVS Unit with Picatinny adapter.
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. 5.16 Using with a daytime riflescope Although the unit does not contain a reticle and thus cannot be used as a riflescope, being mounted on a daytime riflescope or red-dot sight, it enables aiming at night.
5.17 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 goggles to the bridge. In this configuration the unit can be used in a goggle (mounted on a headgear) or handheld. Figure 10. Bridge FIGURE 11.
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 5.5 and 5.6 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!).
