1.7 Gain adjustment
The gain becomes high when rotating clockwise the knob and becomes low when rotating
counterclockwise the knob.

targets can be easily seen.
When the observation range is wide, if the gain is increased, it is effective.
But, due to noise increase, small targets become hard to be seen.
