	FUNCTION SWITCHES

Shutter speed switches

Shutter speeds are selected with DIP switches 8, 9 and 10. DIP switch 7 must be down to enable manual shutter speed selection. For EI, BLC and Flickerless functions, switch 7 must be up.

7 8 910		7 8 910		7 8 910		7 8 910

	1/4,000		1/1,000		1/250		1/50

EI (Electronic Iris)

The EI (Electronic Iris) feature compensates for excessive light level by automatically adjusting shutter speed. Selecting Electronic Iris disables manual shutter speed selection. The Electronic Iris setting must not be used when the camera is set to Flickerless mode. The default setting is Electronic Iris ON.

BLC (Back Light Compensation)

The BLC (Back Light Compensation) feature compensates for back-lit scenes by enhancing objects in the center of the scene which would previously have been in silhouette. Select ON or OFF using the BLC switch. Default is OFF. BLC will only function with a manual iris lens when the Electronic Iris feature is switched on. For direct drive and auto iris lenses, BLC will still function even though the Electronic Iris feature is switched off.

Flickerless

The Flickerless setting can reduce the flicker caused by certain lighting conditions. Choose between ON or OFF. The default setting is OFF. Note that the Electronic Iris setting must be off for correct operation of the Flickerless function.

LENS SELECTION

Suitable lens types are C and CS mount in fixed iris, manual iris, auto-iris or direct drive versions. Sizes are shown below. Cameras are factory set for CS mount lenses. If using a C mount lens, rotate either of the back focus screws approximately 30 turns counterclockwise before installing the lens.
