Item						Function & Setting	Initial Value
SHUTTER	Sets the electronic shutter speed.						1/50
	When the item “SENSE UP” is set to “x2” or higher, the, available settings for the
	SHUTTER are limited to 1/50 and 1/120.
	Setting values : 1/50, 1/120, 1/250, 1/500, 1/1000, 1/2000, 1/4000, 1/10000
				MEMO
			● To reduce the flickering which occurs under fluorescent lighting, set the shutter speed
					to 1/50 if your local power supply frequency is 50 Hz and to 1/120 if it is 60 Hz.
			● When a high shutter speeds are used, white stripes may be observed above and
					below bright objects. This is called the smear phenomenon and is usual to CCD
					cameras.
AGC MODE	Sets the maximum gain of the AGC (Auto Gain Control), which electronically in-						10 dB
	creases the gain when the object is under low light conditions.
	OFF				: Turns the AGC off.
	10 dB : According to the brightness of the object, gain is increased by up to 10 dB
	20 dB : According to the brightness of the object, gain is increased by up to 20 dB
	SUPER : Use this setting when brightness is still insufficient under the “20 dB”
					setting.
				MEMO
		● When the item “B&W” is set to “AUTO”, [SUPER] is displayed when the item “AGC MODE”
				is set to “SUPER”, and [20 dB] is displayed for other settings. Increase the gain up to the
				value displayed.
		● Note that increasing gain affects picture quality.
		● When the “SUPER” setting is used, the AGC operation may take a while to adjust to
				sudden drastic changes in the brightness level.
