OPERATING THE SYSTEM
3.1 SYSTEM DESCRIPTION
The MNVD utilizes the principle of intensification of the residual light that is reflected from the
surrounding objects. The optical system of the unit consists of a lens, an image intensifier tube (IIT), and
an eyepiece.
This device operates with a single control knob for turning on/off the device and adjusting the gain. The
device allows for vertical adjustment (using the head or helmet mount), fore-and-aft adjustment,
objective lens focus, and eyepiece focus. The monocular is equipped with an infrared (IR) light-emitting
diode (or IR illuminator) to provide additional illumination for close distance. There are two levels of IR
illumination power. The operating modes of IR illuminator are controlled by a separate button. The
monocular is also equipped a low battery indicator, a bright light cutoff system indicator, and IR
illuminator indicator in the field of view of device.
