Press	the	AV-MUTE	 button	to	turn	 off	the	 image	 and	sound	 for	a	short	 period	 of	time. 	
Press	again	to	restore	the	image	and	sound.
The	projector’s	 power-saving	 function	will	work	 10	seconds	 after	the	image	 is	turned	
off.
As	a	result,	the	lamp	power	will	be	reduced.
NOTE:
•	 Even	though	the	image	is	turned	off,	the	menu	still	remains	on	the	screen.
•	 Sound	from	the	AUDIO	OUT	jack	(Stereo	mini)	can	be	turned	off.
•	 Even	 when	the	power-saving	 function	works,	the	lamp	 power	 may	be	restored	 to	its	 original	
level	temporarily.
•	 To	 restore	 the	image,	 even	if	you	 press	 the	AV-MUTE	 button	immediately	 after	the	start	 of	the	
power-saving	function,	the	lamp	brightness	may	not	be	restored	to	its	original	level.
❷ Freezing a Picture

sound	temporarily	during	display	of	freezed	image.
❸ Enlarging a Picture
You	can	enlarge	the	picture	up	to	four	times.
NOTE:	
•	 Depending	 on	the	 input	 signal,	 the	maximum	 magnification	 may	be	less	 than	 four	times,	 or	this	
feature	is	not	available.
•	 This	feature	is	not	available	with	USB	Display.

❹ 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	P501X/P451W/PE501X 	and 	approx. 	83% 	on	
P451X/P401W)	 The	lamp	 life	will	 extend	 by	lowering	
the	lamp	power.
Steady	Green	
light
[ECO]
Lamp	 power	 consumption. 	(approx.60%	 brightness	
on	P501X/P451W/PE501X 	and 	approx. 	67% 	on	
P451X/P401W)	 The	lamp	 life	will	 extend	 longer	than	
the	one	 on	NORMAL	 mode	by	controlling	 power	ap-
propriate 	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.

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.
•	 Immediately	 after	[ECO	 MODE]	 is	changed	 from	[ECO]	 to	one	 of	[OFF],	 [AUTO	 ECO],	or	[NORMAL],	 the	lamp	 brightness	 may	
decrease	temporarily.	This	is	not	a	malfunction.
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	113)
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. 
						

							32
3. Convenient Features
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.
•	 The	factors	 for	[TOTAL	 COST	SAVINGS]	 can	be	changed	 from	the	menu	 ([CARBON	 CONVERT]	 and	[CURRENCY	 CONVERT]).	(→	
page	112)
•	 The	currency	unit	for	[TOTAL	COST	SAVINGS]	can	be	changed	from	the	menu	([CURRENCY]).	(→	page	112)

The	adjustable	ranges	for	3D	Reform	are	as	follows:
HORIZONTALVERTICAL
CORNERSTONE
Max. 	+/−	30°	approx.Max.	+/−	30°	approx.KEYSTONE
*	 The	following	are	conditions	under	which	the	maximum	angle	is	achieved:
•	 When	the	lens	shift	is	set	to	the	center
	 When	 the	lens	 shift	is	used	 and	yet	the	 image	 is	not	 displayed	 in	the	 center	 of	the	 screen,	 the	adjustable	 range	
will	be	increased	or	decreased.
•	 Image	is	projected	in	maximum	wide	with	the	zoom
NOTE:	
•	 Even	when	the	projector	is	turned	on,	the	last	used	correction	values	are	applied.
•	 If	the	Cornerstone	 screen	is	unavailable	 (grayed),	reset	the	current	 correction	 data.	The	Cornerstone	 function	becomes	 avail-
able.
•	 The	range	of	keystone	correction	is	not	the	maximum	tilt	angle	of	projector.
NOTE:	Using	[KEYSTONE]	correction	can	cause	the	image	to	be	slightly	blurred	because	the	correction	is	made	electronically.
