	Item		Functions and set values	Initial value
	FAST LIMIT	This sets the fastest value of a shutter speed when AUTO is set.		1/100000
		The MANUAL, M. ExDR, A. ExDR set value is displayed as “- - -” and
		cannot be changed. The higher the shutter speed becomes, the more
		smear phenomenon is emphasized, which is peculiar to the CCD.
		[Set values: 1/1000, 1/2000, 1/4000, 1/10000, 1/20000, 1/40000, 1/100000]
	ExDR	This sets the signal level of the composing high-speed shutter during		NORMAL
	LEVEL	ExDR mode. This is set according to the brightness of a subject.
		When using M.ExDR, be sure to set M.ExDR SPEED in advance.
		When the SHUTTER/ExDR item is set to MANUAL or AUTO,
		“- - -” appears, disabling setting.
		To give priority to the low-brightness parts of the subject…
		increase the value
		To give priority to the high-brightness parts of the subject…
		decrease the value
		[Set values: –5 to NORMAL to 5]
		MEMO
		• In the case of a subject with a large difference in the luminous flux
		density, sometimes images do not change even if ExDR LEVEL is
		varied. However, this occurrence is a peculiarity of the unit and is
		not a malfunction.
	M.ExDR	This sets the composing high shutter speed when ExDR is set to M.ExDR.		1/4000
	SPEED	Set the shutter speed in order that a subject with a high luminous flux
		density (outdoor, etc.) may come out most clearly. This is displayed as “-
		- -” during MANUAL, AUTO or A. ExDR and cannot be set.
		[Set values: 1/500, 1/1000, 1/2000, 1/4000, 1/10000, 1/20000]
AGC MODE		This sets a maximum gain of the AGC (Automatic Gain Control).		20dB
		OFF:	When the AGC function is not used.
		10dB:	When luminous energy is insufficient.
		20dB:	When luminous energy is extremely insufficient.
		SUPER:	When brightness is insufficient even when it is set to 20dB.
		• If the gain is increased, the screen gets rough in a dark place.
		• If it is set to SUPER, it can sometimes consume operation time to
		cope with a drastic level change.
		• When the item “B&W” is set to “AUTO”, [SUPER] is displayed when
		the item “AGC MODE” is set to “SUPER”, and [20dB] is displayed for
		other settings. Increase the gain up to the value displayed.
LOLUX MODE		Used when brightness is low even when setting the AGC MODE.		OFF
		(Functions regardless of the AGC MODE setting.)
		OFF: LOLUX MODE is off
		ON: LOLUX MODE is on (+ 6dB)
SENSE UP		This item makes up a sensitivity should be heightened automatical-		OFF
		ly when a subject becomes dark.
		In case of the X32 AUTO, the sensitivity is automatically heightened
		up to 32 times continuously as compared with standard.
		As the sensitivity becomes higher, the shutter speed becomes lower,
		resulting in unnatural motion.
		If SHUTTER/ExDR is set to MANUAL or the M.ExDR,
		“- - -” will appear, disabling the SENSE UP function.
		[Set values: OFF, X2 AUTO, X4 AUTO, X8 AUTO, X16 AUTO, X32
		AUTO]
		MEMO
		• When the magnification of SENSE UP is enhanced, the screen
		can become coarse or whitish, or whitish flaws can emerge
		sometimes, but this is not abnormal.
		• When the item SENSE UP is set other than to OFF, a flicker can
		occur under a fluorescent lamp, mercury lamp, etc. However, this
		occurs by principle of SENSE UP, and therefore this is not a
		malfunction.
