2. Projecting an Image (Basic Operation)
NOTE:
•	 If	the	projection	angle	is	the	same	as	in	the	last	use,	the	previous	correction	setting	values	are	retained	in	the	memory.
•	 When	doing	Step	2,	adjust	the	position	of	image	so	that	the	screen	is	smaller	than	the	area	of	the	projected	area.
•	 To	reset	the	3D	Reform	correction	setting	values,	press	and	hold	the	3D	REFORM	button	for	a	minimum	of	2	seconds.
•	 Each	time	the	3D	REFORM	 button	is	pressed,	 the	item	 will	change	 as	follows:	 KEYSTONE	→	CORNERSTONE	→ None  →	KEY-
STONE	→ ...
For	information	on	[CORNERSTONE],	see	“Correcting	Horizontal	and	Vertical	Keystone	Distortion	(Cornerstone)”	on	page	37.
•	 The	 Cornerstone	 adjustment	will	not	be	available	 during	the	Keystone	 adjustment.	 To	perform	 the	Cornerstone	 adjustment,	press	
and	hold	 the	3D	REFORM	 button	for	a	minimum	 of	2	seconds	 to	reset	 the	Keystone	 correction	 setting	values.	 The	Keystone	
adjustment	 will	not	be	available	 during	the	Cornerstone	 adjustment.	To	perform	 the	Keystone	 adjustment,	 press	and	hold	 the	3D	
REFORM	button	for	a	minimum	of	2	seconds	to	reset	the	Cornerstone	correction	setting	values.
•	 The	3D	Reform	feature	can	cause	an	image	to	be	slightly	blurred	because	the	correction	is	made	electronically.
5.	 Repeat	steps	2	and	4	to	correct	keystone	distortion.
6.	 After	completing	Keystone	correction, 	press	the	EXIT	button.
 The Keystone screen will disappear.
•	 To	 perform	 Keystone	 correction	 again,	press	the	3D	REFORM	 button	
to display the Keystone screen and repeat above steps 1 to 6.

 Turning off the Projector
To turn off the projector:
1.	 First,	press	 the		(POWER)	 button	on	the	 projector	
cabinet	 or	the	 POWER	 OFF	button	 on	the	 remote	 con-
trol. 
  The  [POWER  OFF  /  ARE YOU  SURE  ?  /  CARBON  SAV-
INGS-	SESSION	0.000[g-CO2]]	message	will	appear.
2.	 Secondly, 	press 	the 	ENTER 	button 	or 	press 	the 	 
(POWER)	or	the	POWER	OFF	button	again.
 The lamp will turn off and the projector will go into standby 
mode. When  in  standby  mode,  the  POWER  indicator  will 
light orange and the STATUS indicator will light green when 
[NORMAL] is selected for [STANDBY MODE]. 
3.	 Press	the	main	power	switch	to	the	OFF	position	(O). 	
 The  POWER  indicator  will  go  off  and  the  main  power  will 
turn off.
Power	On
Steady blue light Standby
Steady  
orange light
Press twice
 CAUTION:
Parts	
of	the	 projector	 may	become	 temporarily	 heated	if	the	 projector	 is	turned	 off	with	 the	POWER	 button	or	if	the	
AC	power	supply	is	disconnected	during	normal	projector	operation.
Use	caution	when	picking	up	the	projector.
NOTE:
•	 While	the	POWER	indicator	is	blinking	blue	in	short	cycles,	the	power	cannot	be	turned	off.
•	 You	cannot	turn	off	the	power	for	60	seconds	immediately	after	turning	it	on	and	displaying	an	image.
•	 Wait	 at	least	 20	minutes	 after	the	power	 is	turned	 on	(after	 starting	 to	project)	 before	turning	 the	AC	power	 off	while	 an	image	 is	
being projected or while the cooling fan is running.
•	 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	input	 connector	 or	the	 power	 plug’s	contact.	 To	turn	 off	the	 AC	power	 while	an	image	 is	being	
projected,	use	the	projector's	main	power	switch,	the	power	strip’s	switch,	the	breaker,	etc.
•	 Do	 not	disconnect	 the	AC	power	 supply	 to	the	 projector	 within	10	seconds	 of	making	 adjustment	 or	setting	 changes	 and	closing	
the menu. Doing so can cause loss of adjustments and settings.

 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]	→	[BASIC]	→	[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]	 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].

3. Convenient Features
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	125)
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,	the	amount	of	CO2 emission 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.
