Lens/Autoiris Adjustment
The manual iris lens can be manually adjusted for focus and angle of view. On the lens, focus (near to
infinity) is the front ring and the telephoto/wide adjustment is the end ring; iris is fixed. On autoiris lenses, iris
adjustment may be required if the picture appears dark or grainy or has poor color. There is a potentiometer
(VR1) on the camera front board to adjust the autoiris. Refer to Figure 5. Turning the potentiometer opens
and closes the iris to regulate light extremes. Turning the potentiometer clockwise opens the iris wider,
allowing more light.
