2.3.3. ELECTRONIC CIRCUIT FUNCTION
The electronic circuit regulates the direct current voltage from the battery to the image intensifier and
IR source as required. It also monitors the output voltage of the battery and turns on a low-battery
indicator when the available battery voltage is 1.9 – 2.1 Vdc.
a. Power Source
The electronic circuit is powered by one battery.
b. High Light Cut-Off
The monocular will automatically turn off after 70 ±30 seconds of operation in daylight or other bright-
ly lit environments. Individual bright lights (headlights, flashlights, or other concentrated light sources)
will not actuate the high light detector located on the front of the monocular. To turn the monocular
back ON, turn the power switch to RESET/ OFF, and then to ON again.
