Gain is a feature that optimizes the video's brightness over long runs of coaxial cable. Gain increases the video
signal's amplitude to increase the brightness of darkened video and to reduce the noise of weakened video. Use
the joystick to adjust the gain. Up increases and down decreases the gain.
To set the gain value, do the following:
1. Navigate to Gain (0-31).
2. Press iris +.
3. Use the joystick up to increase the gain and down to decrease the gain. Choices range from 0 to 31.
Default is 0.
CAUTION: Lift and gain compensate for long runs of video coaxial cable. Only qualified personnel should adjust these
settings. Incorrect adjustments can impair video quality.
