4. IR ILLUmInATOR
Infrared illuminators are used in areas where the level of light is not sufficient for the unit to generate a
bright, clear image. An IR illuminator provides infrared light which, although invisible to the naked eye,
can greatly enhance the performance of night vision devices. Turn on the IR illuminator when working
in total darkness. Remember that the beam emitted by your IR illuminator will lose its brightness over
long distances.
IR ILLUmInATOR InSTALLATIOn
The IR810/IR850 is a removable infrared illuminator that can
be installed on the rail of the Nemesis. To install the IR illumi-
nator on your sight, perform the following:
1) Loosen the fixing screw on the IR illuminator mount.
2) Place the IR illuminator on the Picatinny rail
3) Tighten the fixing screw.
IR ILLUmInATOR OPERATIOn
The Armasight IR810/IR850 runs on a single CR123A battery. To install the battery, unscrew the battery
compartment cap and insert the battery in accordance with the polarity markings on the unit’s body.
Screw the battery compartment cap back into position.
To turn the IR illuminator on, rotate the operation switch from the OFF position.
To adjust the power and brightness of the beam emitted by the IR illuminator, rotate the illuminator
operation switch.
Focus the IR beam to change the field of coverage. To focus the beam, rotate the IR illuminator lens until
the image becomes clear.
Adjust the IR spot position in the field of view of the NVD as
follows:
1) Loosen the screw of the clamp on the IR illuminator
mount.
2) Turn on the sight and the IR illuminator.
3) Carefully move the lens of the IR illuminator up and down
and side to side. While looking through the eyepieces of
your device, observe the IR spot position.
4) Tighten the fixing screw of the clamp once the IR spot is
centered in the field of view.
6. mAInTEnAnCE PROCEDURES
The Nemesis should always be stored in the supplied packaging, particularly in heated and ventilated
