    1. OVERVIEW Your NVS 7 series device (the “Unit”) is an optoelectronic goggle intended for observation of objects and orientation at night or under dark conditions. The Unit is equipped with an advanced Generation 3 (“Gen 3”) image intensifier tube (“IIT”), which amplifies low light, such as moonlight, starlight or man- made light and converts it into a clear visible image.

    5. OPERATION INSTRUCTIONS Installing battery Unpack the device. Unit is supplied with battery not installed. Prior to installing the battery, make sure the AUTO/OFF/ON/IR switch (1, Fig.1) is in the OFF position and the objective lens cap (6, Fig, 1) is on. Unscrew the battery compartment cover (5, Fig.1), and install 2 fresh AA batteries.

    3). When this indicator is blinking this indicates low battery power. For uninterrupted operation keep fresh batteries ready and replace them on time. If this indicator is displayed as a solid red light, this indicates that the IR illuminator is activated. This warning is intended to prevent the user from unintentionally giving away their position.
  • Page 15: Focusing The Unit

    Focusing the Unit Turn on the Unit. Direct the device 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 each eyepiece (3, Fig. 1). Once focus is nearly achieved, rotate the objective lens (7, Fig.

    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.
  • Page 17: Auto Shut Off At Bright Light

    Auto shut OFF at bright light Each unit has a built-in high light sensor located near the IR illuminator (10, Fig. 1). This sensor shuts the goggles off after approximately 40 seconds of exposure to light exceeding 40 lux. To reset the device after auto shut off, switch it off and then back on as described in Section 5.

    the IIT in changing lighting conditions. Auto-gating turns off the photocathode voltage for brief periods of time, but the effect is not visible to the human eye. This serves not only to protect the IIT from exposure to bright lighting sources, but also to automatically provide the user with the optimal image regardless of prevailing light condition.
  • Page 19 This function is still active in the device equipped with an auto- gated IIT. The BSP reduces voltage to the photocathode rather than the microchannel plate. The BSP protects the image intensifier tube from damage and enhances its lifetime. This function works in bright light conditions that create input light with intensity higher than 0.1lux.
