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.
1. Turn toward L (low) to make the picture darker.
2. Turn toward H (high) to make the picture brighter.

BACKLIGHT CONTROL ADJUSTMENT

You can compensate for backlight conditions by turning the backlight control (BLC) screw.
When using this unit under backlight conditions, turn the BLC screw toward AV.
