❹ Changing Eco Mode/Checking Energy-Saving Effect 
Using Eco Mode [ECO MODE]
When	the	[LIGHT	MODE]’s	[ECO	MODE]	is	set	to	[ECO1]	or	[ECO2],	the	brightness	and	the	operating	sound	are	
reduced.	Furthermore,	the	po wer	consumption	is	decreased	and	the	projector’ s	CO2	emissions	are	reduced.

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 ▼▲ buttons to select, then press the ENTER button.
 The [ECO MODE] selection screen turns off and the projector s witches to the selected mode.
•	 When	in	the	[ECO	MODE],	the	LIGHT	indicator	lights	green.
NOTE:	
•	 The	[ECO	MODE]	can	be	changed	by	using	the	menu.
	 Select	[SETUP]	→	[GENERAL]	→	[LIGHT	MODE]	→	[ECO	MODE].
•	 The	[LIGHT	HOURS	USED]	can	be	checked	in	[USAGE	TIME].	Select	[INFO.]	→	[USAGE	TIME].
•	 After	a	lapse	of	1	minute	from	when	the	projector	displays	no-signal	guidance,	a	blue,	black	or	logo	screen,	the	projector	goes	
into	[ECO2]	automatically.	The	projector	will	return	to	its	original	setting	once	a	signal	is	accepted.
•	 If	the	projector	inside	te mperature	be comes	hi gh	ca used	on	th e	hi gh	ro om	te mperature,	th e	pr ojector	ma y	de crease	th e	br ightness	
temporarily	for	protecting	itself.	This	is	a	protective	function	called	[FORCED	ECO	MODE].	When	the	projector	is	in	the	[FORCED	
ECO	MODE],	the	thermometer	symbol	[		]	is	indicated	at	the	right	bottom	of	the	screen.	When	the	projector	inside	temperature	
goes	down	by	cooling	the	room	or	setting	the	fan	mode	to	[HIGH],	the	[FORCED	ECO	MODE]	will	be	released	and	the	projector	
will	be	back	to	the	original	setting	state.	During	the	[FORCED	ECO	MODE],	it	disables	to	change	the	state	by	changing	the	setting	
of	the	[ECO	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	[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	65)
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	[ECO1]/[ECO2]	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.

❻ Viewing 3D Images
The	projector	provides	3D	images	to	a	user	wearing	commercially	available	LCD	shutter	eyeglasses.
 CAUTION
Health precautions
Before	viewing,	be	sure	to	read	health	care	precautions	that	may	be	found	in	the	user’s	manual	included	with	your	LCD	
shutter	eyeglasses	or	your	3D	compatible	content	such	as	DVDs,	video	games,	computer’s	video	files	and	the	like .
To	avoid	any	adverse	symptoms,	heed	the	following:
•	 Do	not	use	LCD	shutter	eyeglasses	for	viewing	any	material	other	than	3D	images.
•	 Allow	a	distance	of	2	m/7	feet	or	greater	between	the	screen	and	a	user.	Viewing	3D	images	from	too	close	a	
distance	can	strain	your	eyes.
•	 Avoid	viewing	3D	images	for	a	prolonged	period	of	time.	Take	a	break	of	15	minutes	or	longer	after	ev ery	hour	
of	viewing.
•	 If	you	or	any	member	of	your	family	has	a	history	of	light-sensitive	seizures,	consult	a	doctor	before	viewing	3D	
images.
•	 While	viewing	3D	images,	if	you	get	sick	such	as	nausea,	dizziness,	queasiness,	headache,	eyestrain,	blurr y	
vision,	convulsions,	and	numbness,	stop	viewing	them.	If	symptoms	still	persist,	consult	a	doctor.	
•	 View	3D	images	from	the	front	of	the	screen.	Viewing	from	an	angle	may	cause	f atigue	or	e yestrain.	
LCD shutter eyeglasses (recommended)
•	 Use	commercially	available	DLP®	Link	or	other	method	compatible	LCD	shutter	eyeglasses.
Steps for viewing 3D images on the projector

To	view	3D	images,	see	page	33.
Select	[HDMI1],	[HDMI2],	[COMPUTER],	[VIDEO],	or	[HDBaseT].
NOTE:
•	 The	maximum	distance	for	viewing	3D	images	is	10	m/394	inches	from	the	screen	surface	under	the	following	restrictions:
-	 Brightness	on	the	projector:	2000	lumens	or	greater

-	 Viewing	position:	Facing	straight	towards	the	screen	center
-	 Outside	light:	None
-	 LCD	shutter	eyeglasses:	DLP®	Link	compatible	3D	eyeglasses
•	 If	3D	content	is	played	back	on	your	computer	and	the	performance	is	poor	it	may	be	caused	by	the	CPU	or	graphics	chip.	In	this	
case	you	may	have	difficulty	seeing	the	3D	images	as	they	were	intended.	Check	to	see	if	your	computer	meets	the	requirements	
provided	in	your	user’s	manual	included	with	your	3D	content.
•	 The	DLP®	Link	compatible	LCD	shutter	eyeglasses	allow	you	to	view	3D	images	by	receiving	synch	signals,	which	are	included	
in	left	eye	and	right	eye	images,	reflected	from	the	screen.	Depending	on	environments	or	conditions	such	as	the	ambient	bright-
ness,	screen	size	or	viewing	distance,	the	LCD	shutter	eyeglasses	may	fail	to	receive	synch	signals,	causing	poor	3D	images.
•	 When	the	3D	mode	is	enabled,	the	Keystone	correction	range	will	be	narrower.
•	 When	the	3D	mode	is	enabled,	the	following	settings	are	invalid.
	 [WALL	COLOR],	[PRESET],	[REFERENCE],	[COLOR	TEMPERATURE]
•	 Refer	to	the	[SOURCE(2)]	screen	under	the	[INFO.]	menu	for	information	on	whether	the	input	signal	is	3D	compatible.
•	 Signals	other	than	those	listed	in	“Compatible	Input	Signal	List”	on	page	126	will	be	out	of	range	or	will	be	displayed	in	2D.
Using a 3D emitter
This	projector	can	be	used	to	watch	videos	in	3D	using	commercially-available	active	shutter-type	3D	ey ewear.	In	
order	to	synchronize	the	3D	video	and	eyewear,	a	commercially-av ailable	3D	emitter	needs	to	be	connected	to	the	
projector	(on	the	projector	side).
The	3D	eyewear	receives	information	from	the	3D	emitter	and	performs	opening	and	closing	on	the	left	and	right.	
3D eyewear and 3D emitter preparations
Please	use	an	active	shutter-type	3D	eyewear	that	conforms	with	the	VESA	standard.
A	commercially-available	RF	type	made	by	Xpand	is	recommended.
3D eyewear ������������Xpand X105-RF-X2
3D emitter
 ��������������Xpand AD025-RF-X1
Connect	your	3D	emitter	to	the	3D	SYNC	terminal	of	the	projector.
NOTE:
•	 Use	an	active	shutter	3D	eyewear	(compliance	with	VESA)
•	 Check	the	operating	conditions	described	in	the	user	manual	of	the	Blu-ray	player.
•	 Please	connect	the	DIN	terminal	of	the	3D	emitter	to	the	3D	SYNC	of	the	projector.
•	 The	3D	eyewear	allows	videos	to	be	viewed	in	3D	by	receiving	synchronized	optical	signals	output	from	the	3D	emitter.	As	a	result,	
the	3D	image	quality	may	be	affected	by	conditions	such	as	the	brightness	of	the	surroundings,	screen	size,	viewing	distance,	
etc.
•	 When	playing	a	3D	video	software	on	a	computer,	the	3D	image	quality	may	be	affected	if	the	computer	CPU	and	graphics	chip	
performance	are	low.	Please	check	the	required	operating	environment	of	the	computer	that	is	stated	in	the	operating	manual	
attached	to	the	3D	video	software.

Troubleshooting on viewing 3D images
If	images	will	not	be	displayed	in	3D	or	3D	images	appear	as	2D,	check	the	follo wing	table .	Also	refer	to	the	user’s	
manual	accompanied	with	your	3D	content	or	LCD	shutter	eyeglasses.
Possible	causesSolutions
•	 The	content	you	are	playing	back	is	not	compatible	with	3D.•	 Play	back	a	content	compatible	with	3D.
•	 The	3D	mode	was	turned	off	for	the	selected	source.•	 Use	the	projector’s	menu	to	turn	on	3D	mode	for	the	selected	source.	(→	page	63)
•	 You	are	not	using	our	recommended	LCD	shutter	eyeglasses.•	 Use	our	recommended	LCD	shutter	eyeglasses.	(→	page	33)
•	 If	the	shutter	of	your	LCD	shutter	ey eglasses	cannot	syn-chronize	with	the	currently	projected	source,	the	follo wing	are	possible	causes:
-	 Your	LCD	shutter	eyeglasses	are	not	switched	on.•	 Switch	on	your	LCD	shutter	eyeglasses.For	using	a	3D	emitter:•	 Use	an	active	shutter-type	3D	ey ewear	an d	3D	em itter	re com-
