Infrared (Ir) Illuminator Operations - ATN PS-15 Operator's Manual

C. INFRAREd (IR) ILLUMINATOR OPERATIONS
CAUTION
The IR illuminator is a light source that is invisible to the
unaided eye made use of in the conditions of extreme
darkness. Please keep in mind this illuminator functioning
can be easily detected by other people who use night vision
devices, too.
NOTE
The IR illuminator principally serves to let you see in the
scarcely-lit surroundings at a viewing range of up to 3 meters
optimally.
IR Illuminator gets activated when the operation knob is in "IR"
position. A red light appears in the eyepiece to indicate that the
IR illuminator is operating.
By shifting the focusing lens of the IR pivot plate (B) to cover
the IR illuminator window (C) you can focus the IR into a
spotting position and at a time extend the IR useful range of
observation.
