signal	is	being	input	(by	factory	default	menu	settings).
 
Performing Lens Calibration 
After	installation	or 	replacement 	of 	the 	lens , 	be 	sure 	to 	perf orm	
[CALIBRATION]	by 	pressing 	and 	holding 	the 	ORIENT ATION 	
button	for	at 	least 	tw o 	seconds 	or 	b y 	holding 	the 	CTL 	b utton 	
and	pressing	t he	I NFO/L-CALIB	b utton	o n	t he	r emote	c ontrol.

of	the	27	menu	languages.
To	select	a	menu	language,	follow 	 these 	 steps:
1. Use the ▲, ▼, ◀ or ▶	button 	to 	select 	one 	of 	the 	27 	lan-
guages	from	the	menu.

(→	[LANGUAGE]	on	page	102	and	120)
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 	mal-
function.	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.
-	 Starting	under	low	temperature	conditions
	 If	the	usage 	environment 	temperature 	is 	lower 	than 	the 	projector’ s 	operating 	temperature, 	the 	TEMP . 	indicator 	will 	flash. 	Increase	
the	usage	environment	temperature	to	0°C	or	higher	and	turn	on	the	projector	again.
	 If	you	turn	on	the	projector	at	around	0°C,	it	may	take	5	minutes	to	warm	up	the	projector.
	 During	warm-up,	the	TEMP.	indicator	will	flash.	When	the	warm-up	is	completed,	the	TEMP.	indicator	will	light	out.
-	 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 	P ANEL 	LOCK] 	is 	turned 	on. 	
Cancel	the	lock	by	turning	it	off.	(→ page 126)
-	 If	the	lamp 	fails 	to 	light, 	and 	if 	the 	LAMP 	1 	or 	LAMP 	2 	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. 	W ait 	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\
.

❹ 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 	b utton 	once .	The 	projector 	will 	search 	f or 	the 	a vail-
able	input	source 	and 	displa y 	it.	The 	input 	source 	will 	change 	as 	f ollows:	
COMPUTER1	→	COMPUTER2	→	COMPUTER3	→	HDMI	→	Display-
Port	→	VIDEO 	→	S-VIDEO 	→	VIEWER	→	SLOT	→	COMPUTER1 	→ ...
•	 With	the	SOURCE 	screen 	displa yed, 	y ou 	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.

Press	any	one 	of 	the 	COMPUTER1, 	COMPUTER2, 	COMPUTER3, 	HDMI,	
DisplayPort,	VIDEO, 	 S-VIDEO, 	VIEWER, 	 NETWORK, 	 or 	 SLOT 	 buttons.
Selecting Default Source 
You	can	set 	a 	source 	as 	the 	def ault 	source 	so 	that 	it 	will 	be 	displa yed 	
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 	[DEF AULT 	SOURCE 	SE-
LECT]	and	press	the	ENTER	button.
 The [DEFAULT SOURCE SELECT] screen will be displayed.
 (→ page 131)
5.	 Select	a	sour ce 	as 	the 	default 	sour ce,	and 	press 	the 	ENTER 	b ut-
ton.
6.	 Press	the	EXIT	button	a	few	times	to	close	the	menu.
7. Restart the projector.
 The source y ou 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 	1/3 	IN 	input 	will 	power 	on 	the 	projector 	
and	simultaneously	project	the	computer’s	image.
	 ([AUTO	POWER	ON(COMP1/3)]	→ page 131)
•	 On	the	Windows 	7 	keyboard, 	a 	combination 	of 	the 	Windows 	and 	P 	keys 	allows 	
you to set up external display easily and quickly.

Adjusting the vertical position of a projected image (Lens shift)
 CAUTION•	 Perform	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.
•	 Keep	hands	a way 	from 	the 	lens 	mounting 	por tion 	while 	the 	lens 	shift 	is 	in 	oper ation.	
Failure	to	do	so	could	result	in	hands	being	pinched	by	the	moving	lens.
NOTE:
•	 The	lens	shift 	function 	is 	not 	available 	on 	the 	projector 	with 	NP16FL 	(PX750U2) 	and 	NP06FL 	(PX700W2/PX800X2) 	lens 	installed. 	
	 Return	the	lens	shift	position	to	the	home	position	before	installing	the	lens	to	the	projector.
•	 Shifting	the	lens 	to 	the 	maximum 	in 	two 	directions 	combined 	will 	cause 	the 	edges 	of 	the 	image 	to 	become 	dark 	or 	will 	cause 	
some shadows.
Adjusting with buttons on the cabinet
1.	 Press	one	of	the	LENS	SHIFT	▼▲◀▶ buttons.
2.	 Use	the	LENS	SHIFT	▼▲◀▶ buttons to move the projected image.
Returning	the	lens	shift	position	to	the	home	position
Press	and	hold 	the 	SHUTTER/HOME 	POSITION 	b utton 	f or 	2 	seconds 	to 	retur n 	the 	lens 	shift 	position 	to 	the 	home 	
position	(nearly	center	position)
