❹ Changing Eco Mode/Checking Energy-Saving Effect 
Using Eco Mode [ECO MODE]
The	ECO	MODE	(NORMAL	and	ECO)	increases	lamp	life,	while	low ering	pow er	consumption	and	cutting	down	on	
CO2	emissions.	
Four	brightness	modes	of	the	lamp	can	be	selected:	[OFF],	[AUTO	ECO],	[NORMAL]	and	[ECO]	modes .	
[ECO	MODE]	DescriptionStatus	of	LAMP	indicator
[OFF]The	lamp	brightness	is	100%.Off
[AUTO	ECO]Lamp	power	consumption	will	be	changed	between	
[OFF]	and	[NORMAL]	automatically	according	to	
picture	level
NOTE:	A	bright	gradation	may	be	less	visible	depending	
on	the	image.
[NORMAL]Lamp	power	consumption:	approx.80%	brightness.	
The	lamp	life	will	extend	by	lowering	the	lamp	pow er.	
Steady	Green	
light
[ECO]
Lamp	power	consumption	(approx.	60%	brightness).	
The	lamp	life	will	extend	longer	than	the	one	on	
NORMAL	mode	by	controlling	pow er	appropriate	for	
the	lamp.	The	maximum	power	becomes	equivalent	
to	the	power	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]	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].	The	projector	will	return	to	its	original	setting	once	a	signal	is	accepted.
•	 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	its	original	setting.
	 Thermometer	symbol	[		]	indicates	the	[ECO	MODE]	is	automatically	set	to	[NORMAL]	mode	because	the	internal	temperature	
is	too	high.
•	 Immediately	after	[ECO	MODE]	is	changed	from	[ECO]	to	one	of	[OFF],	[AUTO	ECO],	or	[NORMAL],	the	lamp	brightness	may	
decrease	temporarily.	This	is	not	a	malfunction.

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	to	[AUTO	ECO],	[NORMAL],	or	[ECO].	This	feature	is	called	as	[CARBON	METER].
There	are	two	messages:	[TOTAL	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	70)
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	AUTO	ECO/NORMAL/
ECO	for	ECO	MODE)	×	CO2	conversion	factor.*	When	the	image	is	turned	off	with	the	AV-MUTE	button,	the	amount	of	CO2	em-
mission	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.
