ing the eyepieces either
together or apart so each
eye can observe the entire
field at the same time.
FOCUSING
To focus the NVG-7, first you will need to adjust the diopter.
Simply turn the diopter clockwise until it stops. Then, while
looking through 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
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 different distances.

NVG-7 while remaining almost totally invisible to the naked
eye.
