INGS-	SESSION	0.000[g-CO2]]	message	will	appear.
 
2. Press one among the ENTER, the  (POWER), and the 
POWER OFF button.
	 When	the	projector	is	in	STANDBY	MODE,	the	POWER	
indicator	lights	up	red.	(When	[STANDBY	MODE]	is	in	
[NORMAL]	setting)
•	 If	you	do	not	want	to	turn	off,	select	[NO]	by	◀/▶button	
and	press	ENTER.
3. Make sure the projector is in STANDBY MODE, then 
turn	off	the	main	power	switch	(○ OFF)
	 The	POWER	indicator	will	go	off	and	the	main	pow er	will	
turn	off.
•	 While	the	POWER	indicator	is	blinking	blue	in	short	
cycles,	the	power	cannot	be	turned	off.

							35
NOTE:
•	 Do	not	unplug	the	power	cord	from	the	projector	or	from	the	power	outlet	while	an	image	is	being	projected.	Doing	so	could	
deteriorate	the	projector’s	AC	IN	terminal	or	the	power	plug’s	contact.	To	turn	off	the	AC	power	supply	when	the	projector	is	
powered	on,	use	the	projector’s	main	power	switch,	a	power	strip	equipped	with	a	switch,	or	a	breaker.
•	 Do	not	turn	off	the	main	power	switch	or	disconnect	the	AC	power	supply	within	10	seconds	of	making	adjustments	or	setting	
changes	and	closing	the	menu.	Doing	so	can	cause	loss	of	adjustments	and	settings.

❻ Changing LIGHT MODE/Checking Energy-Saving Effect 
Using LIGHT MODE [LIGHT MODE]
When	either	[ECO1]	or	[ECO2]	in	[LIGHT	MODE]	is	selected,	motion	noise	of	the	projector	is	cut	down	by	lowering	
brightness	of	its	light	source.	By	saving	energy	consumption,	the	CO2	emission	from	this	projector	can	be	reduced.
LIGHT	MODEIcon	at	the	bottom	
of	the	menuDescription
NORMAL
100%	brightness
The	screen	will	be	brightly	lit.
ECO1Brightness	will	be	at	about	80%.
The	cooling	fan	will	also	slow	down	accordingly.
Lower	power	consumption
ECO2Brightness	will	be	at	about	50%.
The	cooling	fan	will	also	slow	down	accordingly.
Lower	power	consumption	considerably
To	turn	on	the	[LIGHT	MODE],	do	the	following:	
1. Press LIGHT button on the cabinet.
•	 In	another	way,	press	ECO/L-SHIFT	button	on	the	remote	control.
	 The	[LIGHT	MODE]	screen	will	be	displayed.
 
2. Press the ENTER button.
	 The	[LIGHT	MODE]	selection	screen	will	be	displayed.
3. Use the ▼▲ buttons to make a selection, and press the ENTER 
button.
	 The	display	will	return	to	the	[LIGHT	MODE]	screen	and	the	selected	
option	will	be	applied.
	 Press	the	MENU	button	to	return	to	the	original	screen.
3. Convenient Features  
						

							40
NOTE: 
•	 The	[LIGHT	MODE]	can	be	changed	by	using	the	menu.
	 Select	[SETUP]	→	[INSTALLATION(1)]	→	[LIGHT	MODE]	→	[LIGHT	MODE].
•	 The	light	module	hours	used	can	be	checked	in	[USAGE	TIME]	on	the	menu.	Select	[INFO.]	→	[USAGE	TIME].
•	 After	a	lapse	of	1	minute	from	when	the	projector	displays	a	blue,	black	or	logo	screen,	[LIGHT	MODE]	will	automatically	switch	
to	[ECO].	
•	 This	projector	equips	the	sensor	to	detect	atmospheric	pressure	and	temperature	and	the	projector	controls	the	power	based	on	
the	detected	values.	When	the	projector	is	used	in	high	altitude	and	high	temperature,	the	light	source	brightness	becomes	lower	
regardless	of	the	setting	for	LIGHT	MODE.	This	is	called	“Forced	ECO	MODE”.	Please	refer	the	below	table	for	the	conditions	and	
output	power	in	Forced	ECO	MODE.
AltitudesAtmospheric	temperature
5–25°C
(41–77°F) 26–30°C
(78–86°F) 31–35°C
(87–95°F) 36–40°C
(96–104°F)

0–1200	m	(0–4000	ft)100% 80%
•	 When	the	projector	is	in	the	Forced	LIGHT	MODE,	the	picture	brightness	decreases	slightly	and	the	TEMP.	indicator	lights	orange.	
At	the	same	time	the	Thermometer	symbol	[		]	is	displayed	at	the	bottom	right	of	the	screen.
	 When	the	projector	comes	back	to	normal	temperature,	the	Forced	ECO	MODE	is	cancelled	and	the	[LIGHT	MODE]	returns	to	
[NORMAL]	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	[LIGHT	MODE]	
is	set	to	either	[ECO1]	or	[ECO2].	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	137)
The	[CARBON	SAVINGS-SESSION]	message	shows	the	amount	of	CO2	emission	reduction	between	the	time	of	
changing	to	LIGHT	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	shown	below	is	used	to	calculate	the	amount	of	CO2	emission	reduction.	Amount	of	CO2	emission	reduction	=	(Power	
consumption	in	[NORMAL]	LIGHT	MODE	–	Power	consumption	in	current	setting)	×	CO2	conversion	factor.*	When	an	energy-
saving	LIGHT	MODE	is	selected,	or	the	Lens	Shutter	is	used,	there	will	be	a	further	reduction	in	CO2	emission.
*	 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	[LIGHT	MODE]	is	turned	on	or	off.
