Ir Illuminator Operation - ATN NVG-7 Operator's Manual

NOTE
we suggest that you focus the diopter during daylight with the
filter on.
Next focus the front lens until the image and the grain are both sharp.
When you are in low-light conditions and the daylight filter is off, you
may focus the front lens to receive sharp image, the diopter should
not be adjusted.
NOTE
The front lens should be readjusted as you view objects at differ-
ent distances.

FIGURE 2-18. NVG-7 BUIlT-IN INFRA-RED IllUMINATOR
Infra-red illuminators, or Ir illuminators, are common to night vision.
the Ir light greatly enhances the performance of the NVG-7 while
remaining almost totally invisible to the naked eye.
The NVG-7 goggles have a built in IR with indicator "oN" light within
the FoV. to turn the Ir on, push the button by long press (more than
1.5 sec.). It is important to remember that the Ir illuminator is simply
an infra red light source, and like any light source, it may loose its ef-
fectiveness over a great distance.
to turn the Ir off, push the button again by long press (more than 1.5
sec.).
