1. OVERVIEW Your NVS 14 series device (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 (“Gen 3”) image intensifier tube (“IIT”), which amplifies low light, such as moonlight, starlight or man-made light. The Unit is waterproof to the depth of 1 meter for 30 minutes (with the exception of NVS 14-3GCS which is waterproof to 20 meters for 30 minutes). 3x, 4x and 8x a

5. OPERATION INSTRUCTIONS Installing battery Unit is supplied without a battery installed. Prior to installing the battery, make sure the On/Off/IR/Auto switch (1, Fig.1) is in the OFF position and the objective lens cap is on. The Unit can operate on either a single AA or CR-123 lithium battery. Lithium batteries hold a charge longer than conventional batteries and provide better performance at low temperatures. To install a battery remove the battery compartment cover (6, Fig.1) b

the screen is not lit ensure the batteries installed are charged and the polarity is correct. When the Unit is ON you may see a red and/or yellow LED indicator in the field of view (Fig. 2). When the yellow or red LED indicators are flashing, the remaining battery power is low and it should be changed. For uninterrupted operation keep a fresh battery ready and FIGURE 2 replace it on time. If the red LED IR illuminator indicator (red, indicator is lit solidly, the IR left), Low

Switching the Unit off After you have finished using the Unit, turn it off by rotating the On/Off/IR/Auto switch to the ‘OFF’ position. Replace the objective lens cap. If storing the unit for an extended period, remove batteries. Place Unit in appropriate storage container. Adjusting to individual vision Turn on the Unit. Direct the Unit at an object placed within 8-15 m from the viewer. While looking through the Unit at the object, first rotate the diopter adjustment ring on the eye

Auto shut OFF at bright light Each unit has a built-in high light sensor located near the IR illuminator (2, Fig. 1). This sensor shuts the monocular off after -1 about 45 seconds of exposure to light exceeding 10 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. It protects the tube against excessive light exposure only in order to avoid perman

To set comfortable eye-relief (the distance between your eye and the eyepiece), loosen tightening screw on the headgear 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) using four screws (Fig. 3) instead. US type helmet clip is optional and must be ordered seperately. To switch between left and right eye, press the flip button (5, Fig.

5.2 Installation of add-on lenses. Always ensure that the Unit is switched off when adding or removing an objective lens. To attach the afocal 3x add-on lens to the Unit, turn off the monocular. Remove the objective lens cap. Press the 3x 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. FIGURE 4 NVS 14 with afocal 3x lens

3. To detach the current lens: hold the lens by its base and rotate it counter-clockwise. Once the lens has been removed, store it in a safe, clean space. 4. To attach desired lens: rotate it clockwise along the threading until snug—do not overtighten. The threads are very fine (to prevent humidity penetration) and can be damaged easily. Do not apply force when rotating the lens. If the desired lens does not rotate smoothly along the threading, make sure that the threads are aligned. T
