The	maximum	power	becomes	equivalent	to	the	pow er	
in	NORMAL.
To	turn	on	the	[ECO	MODE],	do	the	following:	
1.	 Press	the	ECO	Button	on	the	remote	control	to	display	[ECO	MODE]	screen.
2.	 Press	the	ECO	button	again	to	select	a	mode	you	wish.	
•	 Each	time	the	ECO	button	is	pressed,	the	choices	will	be	changed:
 OFF → AUTO ECO → NORMAL → ECO → OFF
TIP:	
•	 The	leaf	symbol	at	the	bottom	of	the	menu	shows	the	current	selection	of	ECO	mode.
NOTE:	
•	 The	ECO	MODE	and	DYNAMIC	CONTRAST	features	control	the	lamp	power.	Some	pictures	may	become	extremely	bright	when	
using	both	ECO	MODE	and	DYNAMIC	CONTRAST	features	to	control	the	lamp	power.	To	avoid	this	phenomena,	turn	off	the	ECO	
MODE	and	DYNAMIC	CONTRAST.
•	 Immediately	after	the	menu	item	is	selected	for	[ECO	MODE],	the	screen	may	flicker.	This	is	not	malfunction.
•	 Using	the	projector	in	the	[AUTO	ECO],	[NORMAL],	or	[ECO]	mode	for	[ECO	MODE]	may	cause	poor	halftones	depending	on	the	
projected	image.
•	 When	[ECO]	has	been	set	for	[ECO	MODE],	the	fan	noise	may	change	in	a	certain	cycle.
•	 The	[ECO	MODE]	can	be	changed	by	using	the	menu.
	 Select	[SETUP]	→	[GENERAL]	→	[ECO	MODE].
•	 The	lamp	life	remaining	and	lamp	hours	used	can	be	checked	in	[USAGE	TIME].	Select	[INFO.]	→[USAGE	TIME].
•	 The	projector	is	always	in	[NORMAL]	for	90	seconds	after	the	lamp	is	turned	on	and	while	the	POWER	indicator	is	blinking	green.	
The	lamp	condition	will	not	be	affected	even	when	[ECO	MODE]	is	changed.
•	 After	a	lapse	of	1	minute	from	when	the	projector	displays	no-signal	guidance,	a	blue,	black	or	logo	screen,	[ECO	MODE]	will	
automatically	switch	to	[ECO].
•	 If	the	projector	is	overheated	in	[OFF]	mode,	there	may	be	a	case	where	the	[ECO	MODE]	automatically	changes	to	[NORMAL]	
mode	to	protect	the	projector.	When	the	projector	is	in	[NORMAL]	mode,	the	picture	brightness	decreases.	When	the	projector	
comes	back	to	normal	temperature,	the	[ECO	MODE]	returns	to	[OFF]	mode.
	 Thermometer	symbol	[		]	indicates	the	[ECO	MODE]	is	automatically	set	to	[NORMAL]	mode	because	the	internal	temperature	
is	too	high.

Checking Energy-Saving Effect [CARBON METER]
This	feature	will	show	energy-saving	effect	in	terms	of	CO2	emission	reduction	(kg)	when	the	projector’s	[ECO	MODE]	
is	set.	This	feature	is	called	as	[CARBON	METER].
There	are	two	messages:	[TO TAL	CARBON	SAVINGS]	and	[CARBON	SAVINGS-SESSION].	The	[TO TAL	CARBON	
SAVINGS]	message	shows	the	total	amount	of	CO2	emission	reduction	from	the	time	of	shipment	up	to	now.	You	can	
check	the	information	on	[USAGE	TIME]	from	[INFO.]	of	the	men u.	(→	page	66)
The	[CARBON	SAVINGS-SESSION]	message	shows	the	amount	of	CO2	emission	reduction	between	the	time	of	
changing	to	ECO	MODE	immediately	after	the	time	of	power-on	and	the	time	of	pow er-off.	The	[CARBON	SAVINGS-
SESSION]	message	will	be	displayed	in	the	[POWER	OFF/	ARE	YOU	SURE?]	message	at	the	time	of	po wer-off.
TIP:
•	 The	formula	as	shown	below	is	used	to	calculate	the	amount	of	CO2	emission	reduction.
	 Amount	of	CO2	emission	reduction	=	(Power	consumption	in	[OFF]	for	[ECO	MODE]	−	Power	consumption	in	[ECO	MODE])	×	
CO2	conversion	factor.*	When	the	image	is	turned	off	with	the	AV-MUTE	button,	the	amount	of	CO2	emmission	reduction	will	also	
increase.
*	 Calculation	for	amount	of	CO2	emission	reduction	is	based	on	an	OECD	publication	“CO2	Emissions	from	Fuel	Combustion,	
2008	Edition”.
•	 The	[TOTAL	CARBON	SAVINGS]	is	calculated	based	on	savings	recorded	in	15	minutes	intervals.
•	 This	formula	will	not	apply	to	the	power	consumption	which	is	not	affected	by	whether	[ECO	MODE]	is	turned	on	or	off.
