Operations with IR source
WARNING
The IR source is a light that is invisible to the unaided eye for use during
conditions of extreme darkness. However, the light from the IR source can be
detected by the enemy using night vision devices.
NOTE
The purpose of the IR source is for viewing at close distances up to 3 meters
when additional illumination is needed.
1.
Pull the power switch knob out and rotate clockwise to the IR position. With the
monocular held to the eye, observe that a red light appears in the eyepiece. This
indicates that the IR source is operating.
