NOTE:
The IR illuminator is designed to provide additional illumination (when needed) while viewing
scenes from a distance up to 50m.
To activate the IR illuminator, turn the binoculars on. Pull the IR illuminator out and flip the turn-pull
function switch CW from ON to the IR position. A red light will appear in the eyepiece to indicate that
the IR illuminator is operating.
3.3.3 OPERATING UNDER CHANGING LIGHT CONDITIONS
If the ambient light level exceeds the limit of 100-300 lx for more than 10 s, the Eagle automatic protec-
tive system will shut off the image intensifier tube. If a mission must be carried out in changing light
conditions, the user can shut down the protective system manually by closing the photoreceiver with
the pivotal cap. Putting the cap on the photoreceiver disables the sensor and gives the user an option
of operating or testing the unit under brighter light conditions.
CAUTION:
DO NOT forget to open the photoreceiver after completing your mission.
3.3.4 OPTIONAL LONG-RANGE IR ILLUMINATOR OPERATIONS
CAUTION:
Do not forget that light emitted from the IR illuminator is invisible to the naked eye; however, it
can be easily detected when using night vision devices.
Infrared illuminators are used in areas where the level of light level is not sufficient for surveillance. 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 IR850 when working in total darkness. Please re-
member that the beam emitted by your IR illuminator will lose its brightness over long distances.
The Armasight IR850 runs on one CR123A battery. To install the battery, unscrew the battery compart-
ment cap and insert the battery in accordance with polarity markings. Screw the battery compartment
cap back into place.
Install the IR illuminator on your binoculars as described in Part 3.1.2 of this Manual.
To switch the IR850 ON, rotate the knob from the OFF position.
The power of the beam emitted by the IR850 can be changed. To change the brightness of IR light,
rotate the illuminator knob.
You can change the field of coverage by adjusting the IR
beam. To focus the beam, rotate the IR illuminator lens
until the desired field of coverage is reached. 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 IR850 up and down and
side to side. While looking through the eyepieces of your
device, observe the IR spot position.
4) Once the IR spot is centered in the field of view, tighten
the fixing screw of the clamp.
