3.4 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.

THE PURPOSE OF THE IR SOURCE IS FOR
VIEWING AT CLOSE DISTANCES UP TO 3
METERS WHEN ADDITION
ALILLUMINATION 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.
2. For momentary IR use, turn the power switch knob
clockwise (without pulling) past the ON position. Observe
that a red light appears in the eyepiece. When the switch
knob is released, the knob will return to the ON position
and the IR source will be powered OFF.
