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	112)
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.
