Remote Control Precautions
•	 Handle	the	remote	control	carefully.
•	 If	the	remote	control	gets	wet,	wipe	it	dry	immediately.
•	 Avoid	excessive	heat	and	humidity.
•	 Do	not	short,	heat,	or	take	apart	batteries.
•	 Do	not	throw	batteries	into	fire.
•	 If	you	will	not	be	using	the	remote	control	for	a	long	time,	remove	the	batteries.
•	 Ensure	that	you	have	the	batteries’	polarity	(+/−)	aligned	correctly.
•	 Do	not	use	new	and	old	batteries	together,	or	use	different	types	of	batteries	together.
•		 Dispose	of	used	batteries	according	to	your	local	regulations.
Operating Range for Wireless Remote Control
•	 The	infrared	 signal	operates	 by	line-of-sight	 up	to	a	distance	 of	about	 22	feet/7	 m	and	 within	 a	60-degree	 angle	of	
the	remote	sensor	on	the	projector	cabinet.
•	 The	 projector	 will	not	 respond	 if	there	 are	objects	 between	 the	remote	 control	and	the	sensor,	 or	if	strong	 light	falls	
on	the	sensor. 	Weak	batteries	will	also	prevent	the	remote	control	from	properly	operating	the	projector.

2. Projecting an Image (Basic Operation)
 Connecting Your Computer/Connecting the Power Cord
1.	 Connect	your	computer	to	the	projector.
 This  section  will  show  you  a  basic  connection  to  a  computer.  For  information  about  other  connections,  see “(2) 
Making Connections” on page 143.
 Connect  the  computer  cable  (VGA)  between  the  projector’s  COMPUTER  IN  connector  and  the  computer’s  port 
(mini D-Sub 15 Pin). Turn two thumb screws of both connectors to fix the computer cable (VGA).
2.	 Connect	the	supplied	power	cord	to	the	projector.
 First  connect  the  supplied  power  cord’s  three-pin  plug  to  the  AC  IN  of  the  projector,  and  then  connect  the  other 
plug of the supplied power cord in the wall outlet.
 The projector’s power indicator will light orange* (standby mode).
 The STATUS indicator will also light green*.
 *  
This will apply for both indicators when [NORMAL] is selected for [STANDBY MODE]. See the Power Indicator 
section.(→ page 214) 
COMPUTER IN
Make sure that the prongs are fully inserted into 
both the AC IN and the wall outlet. To wall outlet
 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.

 Turning on the Projector
1. Remove the lens cap.
2.  Press the 	(POWER) button on the projector cabinet 
or the POWER ON button on the remote control. 
  The  POWER  indicator  will  turn  to  blue  and  the  projector 
will become ready to use.
TIP:	
•	 When	 the	message	 “PROJECTOR	 IS	LOCKED!	 ENTER	YOUR	
PASSWORD.” 	is 	displayed, 	it 	means 	that 	the 	[SECURITY]	
feature	is	turned	on.	(→	page	37)
•	 When 	the 	ECO 	message 	is 	displayed, 	it 	means 	that 	[ON] 	is	
selected	for	[ECO	MESSAGE].	(→	page	102)
•	 Pressing	 buttons	such	as	power	 button	 and	MENU	 button	 will	
make	sound. 	To 	turn 	off 	the 	beep 	sound, 	select 	[OFF] 	for 	[BEEP]	
from	the	menu.	(→	page	109)
 After you turn on your projector, ensure that the computer 
or video source is turned on.
NOTE:	A	 blue	 screen	 (blue	background)	 is	displayed	 when	no	signal	
is	being	input	(by	factory	default	menu	settings).
(→	page	214)

2. Projecting an Image (Basic Operation)
Note on Startup screen (Menu Language Select screen)
When	you	first	 turn	 on	the	 projector,	 you	will	get	 the	Startup	 menu.	This	 menu	 gives	you	the	opportunity	 to	select	 one	
of	the	27	menu	languages.
To	select	a	menu	language, 	follow	these	steps:
1. Use  the , ,   or   button  to  select  one  of  the  27 
languages from the menu.
2.  Press the ENTER button to execute the selection.
After 	this 	has 	been 	done, 	you 	can 	proceed 	to 	the 	menu	
operation.
If	you	want,	you	can	select	the	menu	language	later.
(→	[LANGUAGE]	on	page	85	and	101)
NOTE:	
•	 Turning	 the	power	 back	on	directly	 after	it	is	 turned	 off	(by	 direct	 power	 off)	while	 an	image	 is	being	 projected	 can	result	 in	
malfunction.	Be	sure	to	wait	at	least	1	second	before	turning	the	power	back	on.
•	 Keep	the	lens	cap	off	the	lens	while	the	projector’s	power	is	on.
	 If	the	lens	cap	is	on,	it	could	be	warped	due	to	high	temperature.
•	 If	one	of	the	following	things	happens,	the	projector	will	not	turn	on.
-	 If	the	internal	 temperature	 of	the	 projector	 is	too	 high,	 the	projector	 detects	abnormal	 high	temperature.	 In	this	 condition	 the	
projector	will	not	turn	 on	to	protect	 the	internal	 system.	 If	this	 happens,	 wait	for	the	 projector’s	 internal	components	 to	cool	
down.
-	 When	the	lamp	reaches	its	end	of	usable	life,	the	projector	will	not	turn 	on.	If	this	happens,	replace	the	lamp.
-	 If	the	STATUS	 indicator	 lights	orange	 with	the	power	 button	 pressed,	 it	means	 that	the	[CONTROL	 PANEL	LOCK]	is	turned	 on.	
Cancel	the	lock	by	turning	it	off.	(→	page	106)
-	 If	the	lamp	fails	to	light,	and	if	the	STATUS	indicator	flashes	on	and	off	in	a	cycle	of	six	times,	wait	a	full	minute	and	then	turn	
on	the	power.
•	 While	the	POWER	indicator	is	blinking	blue	in	short	cycles,	the	power	cannot	be	turned	off	by	using	the	power	button.
•	 Immediately	 after	turning	 on	the	 projector,	 screen	flicker	may	occur.	 This	is	normal.	 Wait	3	to	 5	minutes	 until	the	lamp	 lighting	 is	
stabilized.
•	 When	the	projector	is	turned	on,	it	may	take	some	time	before	the	lamp	light	becomes	bright.
•	 If	you	turn	 on	the	 projector	 immediately	 after	the	lamp	 is	turned	 off	or	when	 the	temperature	 is	high,	 the	fans	 run	without	 display-
ing	an	image	for	some	time	and	then	the	projector	will	display	the	image.

 Selecting a Source
Selecting the computer or video source
NOTE:	Turn	on	the	computer	or	video	source	equipment	connected	to	the	projector.
Detecting the Signal Automatically
Press	the 	SOURCE 	button 	once. 	The 	projector 	will 	search 	for 	the 	available	
input	source	and	display	it. 	The	input	source	will	change	as	follows: 	
HDMI1	→	HDMI2	→	DisplayPort	→	BNC	→	BNC	 (CV)	→	BNC	 (Y/C)	→ 
COMUPTER	→ ...
•	 With	 the	SOURCE	 screen	displayed,	 you	can	 press	 the	SOURCE	
button	a	few	times	to	select	the	input	source.
TIP:	If	no	input	signal	is	present,	the	input	will	be	skipped.
Using the Remote Control
Press	any	one	of	the	1	(HDMI	1),	2	(HDMI	2),	3	(DisplayPort),	4	(BNC),	
5	(BNC(CV)),	6	(NBC(Y/C)),	7	(Computer),	or	8	(Ethernet)	buttons.
Selecting Default Source 
You	 can	set	a	source	 as	the	 default	 source	 so	that	 it	will	 be	displayed	
each	time	the	projector	is	turned	on.
1. Press the MENU button.
  The menu will be displayed.
2. Press the 	button	 twice	to	select	 [SETUP]	 and	press	 the	 but-
ton	or	the	ENTER	button	to	select	[BASIC].
3. Press the 	button	five	times	to	select	[OPTIONS(2)].
4. Press  the 	button	 five	times	 to	select	 [DEFAULT	 SOURCE	
SELECT]	and	press	the	ENTER	button.
 The [DEFAULT SOURCE SELECT] screen will be displayed.
 (→ page 111)
5. Select a source as the default source, and press the ENTER but-
ton.
6.  Press the EXIT button a few times to close the menu.
7.  Restart the projector.
  The source you selected in step 5 will be projected.
NOTE:	 Even	when	 [AUTO]	 is	turned	 on,	the	[NETWORK]	 will	not	be	automatically	
selected.	To	set	your	network	as	the	default	source,	select	[NETWORK].
TIP:	
•	 When	 the	projector	 is	in	 Standby	 mode,	applying	 a	computer	 signal	from	a	
computer	 connected	 to	the	 COMPUTER	 IN	input	 will	power	 on	the	 projector	
and	simultaneously	project	the	computer’s	image.
	 ([AUTO	POWER	ON(COMP)]	→	page	111)
•	 On	 the	Windows	 7	keyboard,	 a	combination	 of	the	 Windows	 and	P	keys	 allows	
you	to	set	up	external	display	easily	and	quickly.

2. Projecting an Image (Basic Operation)
Adjusting the vertical position of a projected image (Lens shift)
CAUTIONPerform	the	adjustment	 from	behind	 or	from	 the	side	 of	the	 projector. 	Adjusting	 from	the	
front	could	expose	your	eyes	to	strong	light	which	could	injure	them.
Turn the lens shift dials clockwise or counterclockwise.
Vertical	dial
Turn	this	clockwise	or	counterclockwise	to	adjust	the	projection	position	in	the	vertical	direction.
Approximate	 turning	range:	About	 6	turns	 counterclockwise,	 about	2	turns	 clockwise	 when	the	lens	 is	at	 the	 center	
position.
Horizontal	dial
Turn	this	clockwise	or	counterclockwise	to	adjust	the	projection	position	in	the	horizontal	direction.
Approximate	 turning	range:	About	 1	turn	 counterclockwise,	 about	1	turn	 clockwise	 when	the	lens	 is	at	 the	 center	
position.
NOTE:
•	 The	 dials	can	be	turned	 more	than	one	full	turn,	 but	the	projection	 position	cannot	be	moved	 more	than	the	range	 indicated	 on	
the	following	page.
•	 If	the	lens	is	shifted	to	the	maximum	in	the	diagonal	direction,	the	edges	of	the	screen	will	be	dark	or	shaded.
•	 The	lens	shift	function	cannot	be	used	when	using	the	separately	sold	NP11FL	lens.
