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). When

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”, “IR”. In Auto mode the monocular FIGURE 2 will switch off automatically when IR illuminator indicator (red, turned

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. The light gain of the Image Intensifier Tube is set to the level, at which it allows vie

This sensor shuts the monocular off after about 45 second exposure to light exceeding -1 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

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 pre
