3. Convenient Features
 Changing Eco Mode/Checking Energy-Saving Effect 
Using Eco Mode [ECO MODE]
The	ECO	 MODE	 (NORMAL	 and	ECO)	 increases	 lamp	life,	while	 lowering	 power	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	
on	M311X/M271X/M271W 	and 	approx. 	75% 	on	
M361X/M311W) 	The 	lamp 	life 	will 	extend 	by 	lowering	
the	lamp	power.
Steady	Green	
light
[ECO]
Lamp	 power	 consumption	 (approx.	60%	 brightness). 	
The	lamp 	life 	will 	extend 	longer 	than 	the 	one 	on	
NORMAL	 mode	by	controlling	 power	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.
2. Press the  button.
  The area of the magnified image will be moved
3.	 Press	the	D-ZOOM	(−)	button.
 Each time the D-ZOOM (−) button is pressed, the image is reduced.
NOTE:	
•	 The	image	will	be	enlarged	or	reduced	at	the	center	of	the	screen.
•	 Displaying	the	menu	will	cancel	the	current	magnification. 
						

							28
3. Convenient Features
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].
•	 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	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	 [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	96)
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	AUTO	 ECO/NORMAL/
ECO	for	ECO	 MODE)	 ×	CO2	conversion	 factor.*	When	the	image	 is	turned	 off	with	 the	AV-MUTE	 button	or	with	 the	lens	 cover	
closed,	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.
