VIDEO LEVEL SCREEN

	Item			Functions and operation	Variables values
LENS TYPE		Switch over between AUTO and MANUAL according to the lens to be used.			AUTO
		AUTO		: Set it when an automatic iris lens is used.	MANUAL
		MANUAL		: Set it when a manual iris lens is used or no lens is used.
IRIS		Switch over between AUTO and MANUAL for iris setting when a automatic iris lens is used.			AUTO
CONTROL		AUTO		: Iris can be adjusted automatically.	MANUAL
		MANUAL		: Iris can be adjusted by manually.
		Note:
		When AUTO is set, make sure to set the FREEZE item of the FREEZE screen to the
		NORMAL.
SHUTTER		This is to change the shutter mode.			NORMAL
		NORMAL		: Fixed with 1/60 [U Ver.] or 1/50 [E Ver.].	STEP
		STEP		: Shutter speed can be changed at the “LEVEL” item. (Fix value)	EEI
		EEI		: Shutter speed varies automatically depending on brightness of the object.	V.SCAN
				(Max. approx. 1/1920) [U Ver.] , (Max·approx. 1/1600) [E Ver.]
		V.SCAN		: Adjust the shutter speed to the scanning speed of the computer's
				monitor, so that the horizontal lines do not appear when taking a shot
				of the computer monitor. The shutter speed can be varied finely at the
				“LEVEL” item.
		Note:
		This item cannot be set only when the FREEZE item on the FREEZE screen is
		set to NORMAL. (not available with RANDOM, TRG, FLASH, SLOW SHUT).
		The shutter speed is set to that at the FREEZE screen .
	LEVEL	The shutter speed can be varied when the SHUTTER is set to the V.SCAN or the			[U Ver.]
		STEP.			V.SCAN
		Increase shutter speed: Press the DATA+ button.			1/60.6 - 1/9936.4
		Decrease shutter speed: Press the DATA- button.			STEP
		It is recommended to set the RANDOM SHUT to 1/100 [U Ver.] or 1/120 [E Ver.] in			1/100,1/250,
		the area with 50 Hz [U Ver.] or 60Hz [E Ver.] to decrease flickers when an object is			1/500,1/1000,1/2000
		shot under a fluorescent lamp.			[E Ver.]
		Note:
					V.SCAN
		When	the shutter speed is increased, the light volume may not be high
					1/50.4 - 1/9900.0
		enough. Therefore an adjustment of the lens’ iris or sensitivity is necessary.
					STEP
		Also, attention is required to the picture quality because the GAIN is boosted,
					1/120,1/250,
		the sensitivity increases and causes a rough appearance to the picture.
					1/500,1/1000,1/2000
GAIN		Sensitivity mode can be changed.			0 dB
		0 dB	: Sensitivity does not increase.		ALC
		ALC	: GAIN is varied automatically according to brightness.		STEP
		STEP	(Max. GAIN can be set at the next item, ALC MAX.)		V.GAIN
			: Sensitivity can be changed at the “LEVEL” item. (Fix value)
		V.GAIN : GAIN can be varied at the “LEVEL” item.
		Note:
		ALC can not be set when the FREEZE item of the FREEZE screen is set to
		RANDOM TRG, Flash or SLOW.
	LEVEL	The sensitivity can be varied when the GAIN is set to the V.GAIN or STEP.			V.GAIN
		Increase sensitivity: Press the DATA+ button.			+0.2dB - +18.0dB
		Decrease sensitivity: Press the DATA- button.			(0.2 dB step)
					STEP
					+6dB, +9dB, +12dB,
					+18dB
ALC MAX		Max. GAIN for the ALC which changes the sensitivity automatically according to			+6dB
		brightness.			+12dB
		+6 dB: Max. GAIN is 6 dB.			+18dB
		+12 dB: Max. GAIN is 12 dB.
		+18 dB: Max. GAIN is 18 dB.
IRIS DETECT		The setting value of the detection level in the AUTO IRIS mode can be varied.			NORMAL
		NORMAL		: Normal position	PEAK
		PEAK		: The max. value (peak level) of the brightness is detected to make the	AVG
		AVG		highlight object more clearly.
				: The average value of the brightness is detected to make the object
				more clear.
