INCIDENT LIGHT LEVEL ADJUSTMENT
Since the incident light level has been preset at the factory, usually no further adjustment is
required. If the picture is too dark, however, or if the picture’s highlights are extremely
overexposed, adjust the LEVEL adjustment screw. This adjustment can only be used for
auto-iris lenses or CCD iris control.
