These are used to set the special features. The switches in order

are for Flicker less, Back Light Compensation, Electronic

Shutter, Automatic Gain Control, Line-Lock and Auto Iris Lens

type.

Fluorescent On/OFF

This is a function compensates for the flickering images that can

occur in fluorescent light conditions. When filming images in

fluorescent lighting, turn on the Fluorescent function; the default

setting is off.

BLC (Back Light Compensation) On/Normal

When BLC is turned on, the AGC, ES and IRIS operating point is

determined by averaging over the center area instead of entire field-

of-view, so that a dimly-lit foreground object in the center area can

be clearly distinguished from brightly-lit backgrounds. BLC should

not be used unless it is needed to compensate for back-lighting.

The default setting is Normal.
