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.
