2.7 IR LED ILLUMINATOR
WARNING
The IR LED Illuminator is detectable by an enemy
using night vision devices. Detection is easier in
smoky, foggy, or rainy conditions. To reduce the
risk of detection by an enemy using night vision
devices, avoid prolonged activation of the IR LED
Illuminator.
The IR LED Illuminator is used to provide a supplementary
light source in conditions of extreme darkness. In addition to
the IR mode described in Table 2-2, the IR LED Illuminator
may also be activated in a momentary setting. To
momentarily activate the IR LED Illuminator, turn the Mode
Switch to the ON position. Continue turning past the ON
position and hold. The IR LED Illuminator will remain
activated until the Mode Switch is released.
A red light in the eyepiece, just outside the intensified field of
view, indicates that the IR LED Illuminator is activated.
