IR ILLUM Focusing Knob
3.2.h Optical Instrument Reticles (OIR) (Pattern Generators)
NOTE
OIRs are not designed for accurate aiming of the weapon.
Exit port covers are not intended for use over the Optical Instrument Reticles.
When installing the OIR, the top loop is identified by an “ear” on one side.
If the OIR is installed in front of the IR ILLUM and the pattern appears blurry or is
unrecognizable, focus the IR ILLUM to a point. To do this, turn the IR ILLUM CCW
from the shooter’s perspective to mechanical stop, then CW to line up the white
dots.
