The skeletonized design features a single rotary switch for power that also serves as manual gain adjustment. The Dual Focus IR illuminator is activated by pressing the power switch twice. The user can select between Flood and Spot when using the IR illuminator. Indicators in the viewing area alert the user if the IR illuminator is on, or if the unit senses a low battery condition.
The unit is powered by either an onboard 123 battery or auxiliary power from a battery pack using a Fischer style connector. The ANVB has an automatic system power cutoff whenever the ANVB is flipped up into the helmet mounted stow position, and then powers back on when it is flipped back down. This feature can be turned on or off depending on user preference.
Unlike the 1431 MK2, the pods automatically turn off when articulated up. This feature prevents illumination on your helmet when one side is articulated up and ensures that the image intensifiers are ‘off’ in the stowed position with the optical pods folded back against the helmet.
