2.8 GAIN (CONTRAST)
The MNVD is equipped with a gain control knob used to
adjust the gain (contrast) of the viewed image. When
looking through the eyepiece, turning the gain control knob
clockwise will provide more contrast. Turning the gain
control knob counterclockwise will provide less contrast.
2.9 FOCUS
The objective lens must be focused for the viewing distance
being observed. While looking at an object at least 9.8
inches (25cm) from the MNVD, rotate the objective focus
ring for best image clarity. A change in viewing distance
requires that the objective lens be refocused. If already
focused for a distance of at least 250 feet (76m), no change
in focus is required between this distance and infinity.
