4. Convenient Features
 Lamp Mode and Energy-Saving Effect
Selecting	[Quiet]	for	Lamp	mode	will	help	you	to	reduce	CO2 emissions from the projector. 
The Lamp mode enables you to select two brightness modes of the lamp: Normal and Quiet modes. The lamp life 
can be extended by using the Quiet mode.

ness). Steady Green 
light 
Changing Lamp Mode
To	change	the	[Lamp	mode]	from	[Normal]	to	[Quiet],	do	the	following:	
1. Press the MENU button on the remote control to display the menu.
2.	 Select	[Setup]	 →	[General]	
→	[Lamp	mode].
3.  Press the ENTER button to display the Lamp mode menu. 
4.  Press the 
	button	to	select	[Quiet]	and	press	the	OK	button.
5.  Press the OK button to close the menu.
 
N OTE:
•	 The 	projector 	has 	the 	Eco 	message 	function 	that 	will 	show 	the 	status 	of 	Quiet 	mode 	on 	screen. 	Select 	[Setup] 	
→ 	[Menu]	
→ [Eco 
message]	 →	[On].See	page	60
, 61.
•	 The	 lamp	life	remaining	 and	lamp	 hours	 used	can	be	checked	 in	[Usage	 time].	Select	 [Information]	
→	
[Usage	 time].	See	page	
66 .
•	 The	projector	will	only	operate	in	the	[Quiet]	mode	for	90	seconds	immediately	after	the	lamp	is	turned	on.
	 The	lamp	condition	will	not	be	affected	even	when	[Lamp	mode]	is	changed.
•	 If	 there	 is	no	 signal	 for	about	 one	minute,	 the	projector	 will	display	 a	blue,	 black	 or	logo	 background	 (depending	on	setting)	
and	go	
into	[Quiet].
	 The	projector	will	return	to	the	[Normal]	mode	once	a	signal	is	accepted.
•	 If	 the	projector	 is	overheated	 in	Normal	 mode,	there	may	be	a	case	 where	 the	Lamp	 mode	 automatically	 changes	to	Quiet	
mode  to  protect  the  projector.  This  is  called  “forced  cooling  operation”.  When  the  projector  is  in  a  forced  cooling  operation, 
the	 picture	 brightness	 decreases.	 When	the	projector	 comes	back	to	normal	 temperature,	 the	Lamp	 mode	 returns	 to	Normal	
mode.
  Thermometer  symbol  [
]	indicates	 the	lamp	 mode	 is	automatically	 set	to	a	forced	 cooling	 operation	 because	the	internal	
temperature	 is	too	 high.	 In	this	 condition,	 changing	[Lamp	mode]	 setting	 in	the	 menu	 will	not	affect	 the	actual	 lamp	mode	
and	the	LAMP	indicator	lights	green.

4. Convenient Features
Checking Energy-Saving Effect
This  feature  will  show  energy-saving  effect  in  terms  of  CO2	 emission	 reduction	 (kg)	when	 the	projector’s	 [Lamp	
mode]	is	set	to	[Quiet].	This	feature	is	called	as	[Carbon	meter].	
There	 are	two	 messages:	 [Total	carbon	 savings]	 and	[Carbon	 savings-Session].	 The	[Total	 carbon	 savings]	 mes-
sage  shows  the  total  amount  of  CO
2  emission  reduction  from  the  time  of  shipment  up  to  now.  You  can  check  the 
information	on	[Usage	time]	from	[Information]	of	the	menu.	See	page	66 .
The	[Carbon	 savings-Session]	 message	shows	the	amount	 of	CO2  emission  reduction  between  the  time  of 
changing	 to	[Quiet]	 mode	immediately	 after	the	time	 of	power-on	 and	the	time	 of	power-off.	 The	[Carbon	 sav-
ings-Session]	 message	will	be	displayed	 in	the	 [Push	 POWER	 button	again	to	turn	 off	power/	 Carbon	 savings-
Session/23.220(g-CO2)]	message	at	the	time	of	power-off.	
TIP:
•	 The	 formula	 as	shown	 below	is	used	 to	calculate	 the	amount	 of	CO
2	emission	 reduction.	 Amount	of	CO2 emission reduction = 
Power	consumption	in	[Quiet]	for	[Lamp	mode]	–	Power	consumption	in	[Quiet]	for	Lamp	mode	x	CO
2 conversion factor.* 
*	 Calculation	 for	amount	 of	CO
2	emission	 reduction	 is	based	 on	an	OECD	 publication	 “CO2	Emissions	 from	Fuel	Combustion,	
2008	Edition”.	
•	 This	formula	will	not	apply	to	the	power	consumption	which	is	not	affected	by	whether	[Lamp	mode]	is	set	to	[Quiet]	or	not.
