This potentiometer is used only if the camera is fitted with a DC drive Auto Iris lens. It is used to control the amount of light striking the CCD image sensor.

Turn off AGC. With a brightly lit scene adjust LENS-IRIS control for a clean 1 VPP video level with no blooming. Turn AGC back on after adjustment is complete.
