❹ Changing Eco Mode/Checking Energy-Saving Effect Using Eco 
Mode [ECO MODE]
This	feature	enables	you	to	select	two	brightness	modes	of	the	lamp:
OFF	and	ON	modes. 	The	lamp	life	can	be	extended	by	turning	on	the	[ECO	MODE].
[ECO	MODE]	Description
[OFF]
This	is	the	default	setting	(100%	Brightness).
[ON]Low	lamp	power	consumption	(approx. 	80%	Brightness).
To	turn	on	the	[ECO	MODE],	do	the	following: 	
1.	 Press	the	ECO	button	on	the	remote	control	to	display	[ECO	MODE]	screen.
2. Use the ▲ or ▼	button	to	select	[ON].
3.  Press the ENTER button. 
	 To	change	from	[ON]	to	[OFF],	Go	back	to	Step	2	and	select	[OFF]. 	Repeat	Step	3.
NOTE: 
•	 The	[ECO	MODE]	can	be	changed	by	using	the	menu.
	 Select	[SETUP]	→	[INSTALLATION]	→	[LAMP	MODE]	→	[ECO	MODE].
•	 The	lamp	life	remaining	and	lamp	hours	used	can	be	checked	in	[USAGE	TIME].	Select	[INFO.]	→[USAGE	TIME].
•	 [ECO	MODE]	is	always	 set	to	[OFF]	 for	1	minute	 immediately	 after	the	lamp	 is	turned	 on.	The	 lamp	 condition	 will	not	be	affected	
even	when	[ECO	MODE]	is	changed.
•	 After	 a	lapse	 of	1	minute	 from	when	 the	projector	 displays	a	blue,	 black	 or	logo	 screen,	 [ECO	MODE]	 will	automatically	 switch	to	
[ON].	
•	 If	the	projector	 is	overheated	 in	[OFF]	 mode,	 there	may	be	a	case	 where	 the	[ECO	 MODE]	 automatically	 changes	to	[ON]	 mode	
to	protect	 the	projector.	 This	is	called	 “Forced	 ECO	Mode”.	 When	the	projector	 is	in	 the	 Forced	 Eco	Mode,	 the	picture	 brightness	
decreases	 slightly	and	the	TEMP.	 indicator	 lights	orange.	 At	the	 same	 time	the	Thermometer	 symbol	[		]	 is	 displayed	 at	the	 bot-
tom right of the screen.
	 When	 the	projector	 comes	back	to	normal	 temperature,	 the	Forced	 Eco	Mode	 is	cancelled	 and	the	[ECO	 MODE]	 returns	to	[OFF]	
mode.

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	[OFF],	or	[ON]. 	This	feature	is	called	as	[CARBON	METER].
There	 are	two	 messages: 	[TOTAL	 CARBON	 SAVINGS]	 and	[CARBON	 SAVINGS-SESSION]. 	The	 [TOTAL	 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	menu.	(→	page	118)
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	power-off. 	The	 [CARBON	 SAVINGS-
SESSION]	message	will	be	displayed	in	the	[POWER	OFF/	ARE	 YOU	SURE	?]	message	at	the	time	of	power-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	ON	 for	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.
