	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 par ts of the subject…
		increase the value
		To give priority to the high-brightness par ts 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.

Item		Functions and set values	Initial value
PRIORITY	This item sets the order in which the AGC and slow shutter		MOTION
	speed decrease function when the object brightness
	becomes low.
	If B&W item of the B&W/COLOUR mode is set to AUTO, and the
	AGC MODE item or the SENSE UP item is set to OFF, “- - -” will
	appear, disabling any setting.
	MOTION:	Priority is given to motion.
		This is suitable to a subject with quick motion,
		since the AGC (automatic gain control) functions
		with priority when the subject becomes dark.
	PICTURE: Priority is given to image.
		When the subject becomes dark, SENSE UP
		(sensitivity goes up) functions with priority,
		offering suitability that gives priority to image.
BLC	Sets the backlight compensation function. Set when a		OFF
	bright light source, etc. is placed in the same direction as
	the subject.

If the item SHUTTER/ExDR is set to the M.ExDR or the

A.ExDR, “- - -” will appear, and the BLC does not function.

OFF: The backlight compensation function does not work.

AREA 1 to AREA 4: When the SET button is pressed, the fixed light metering areas are displayed. Select one of the four types. (Indicated positions on the screen are rough guides. Execute required settings after checking and confirming the functions on actual images.)
