To focus the NVG-7, first you will need to adjust the diopter. Sim-
ply turn the diopter clockwise until it stops. Then, while looking
throught the diopter at an object, slowly turn the diopter back
counter clockwise until the grain in the image is sharp.
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 fil-
ter is off, you may focus the front lens to receive sharp image,
the diopter should not be adjusted.

illuminator is simply an infra red light source, and like any light
source, it may loose its effectiveness over a great distance.
To turn the IR off, push the button again by long press (more
