4.1.3. 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 dark-
ness. 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 (A) 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 po-
sition and at a time extend the IR useful range of observation.
