Adjusting the vertical position of a projected image (Lens shift)
NOTE:
•	 The	lens	shift	function	is	not	available	on	the	projector	with	NP25FL	(fixed	focus)	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	button	for	2	seconds	 to	return	 the	lens	 shift	position	 to	the	 home	
position	(nearly	center	position)

Focus
Applicable	lens:	NP26ZL/NP27ZL/NP28ZL/NP29ZL/NP32ZL
Use	the	FOCUS	(+)	or	(−)	button	on	the	projector	cabinet	to	obtain	the	best	focus.
TIP:	To	obtain	the	best	focus,	perform	the	following	(for	fixed	installation)
Preparation:	Warm	up	the	projector	for	one	hour.
1.	Use	the	FOCUS	+/−	buttons	to	make	sure	you	obtain	the	best	focus.	If	you	do	not,	move	the	projector	back	and	forth.
2.	Select	the	[TEST	PATTERN]	from	the	menu	and	display	the	test	pattern.	(→ page 109)
•	 You	can	also	use	the	TEST	button	on	the	remote	control	to	display	the	test	pattern.

❻ Correcting Keystone Distortion
When	the	projector	 is	not	 exactly	 perpendicular	 to	the	 screen,	 keystone	 distortion	 occurs.	To	 overcome	 it,	you	 can	 use	
the	“Keystone” 	function,	 a	digital	 technology	 that	can	adjust	 for	keystone-type	 distortion,	resulting	in	a	crisp,	 square	
image.
The	following	 procedure	 explains	how	to	use	 the	[KEYSTONE]	 screen	from	the	menu	 to	correct	 trapezoidal	 distor-
tions.
When	the	projector	is	placed	diagonally	to	the	screen,	
When	 the	projector	 is	set	 up	at	an	 angle	 in	relation	 to	the	 screen,	 adjust	the	Horizontal	 option	of	the	 Keystone	 menu	
so	that	the	top	and	bottom	of	sides	of	the	projected	image	are	parallel.
1.	 Press	the	3D	REFORM	 button	on	the	 remote	 control	 or	the	 projec-
tor cabinet.
	 The	Keystone	screen	will	be	displayed	on	the	screen.
2.  Press  the ▼	button	 to	select	 [VERTICAL]	 and	then	 use	the	◀
  or  ▶
 
so	that	the	left	and	right	sides	of	the	projected	image	are	parallel.
*	Adjust	the	vertical	keystone	distortion.
3.	 Align	the	left	(or	right)	side	of	the	screen	with	the	left	(or	right)	side	
of	the	projected	image.
•	 Use	the	shorter	side	of	the	projected	image	as	the	base.
•	 In	the	right	example,	use	the	left	side	as	the	base.
4. Press the ▲	button	 to	select	 [HORIZONTAL]	 and	then	 use	the	◀
 or 
▶
	 so	 that	 the	top	 and	 bottom	 sides	of	the	 projected	 image	are	par-
allel.
•	 Adjust	the	horizontal	keystone	distortion.

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	41.
•	 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.

❼ Optimizing Computer Signal Automatically
Adjusting the Image Using Auto Adjust
Optimizing	a	computer	image	automatically.	(COMPUTER1/COMPUTER2/COMPUTER3)
Press	the	AUTO	ADJ.	button	to	optimize	a	computer	image	automatically.
This	adjustment	may	be	necessary	when	you	connect	your	computer	for	the	first	time.

NOTE:
Some	signals	may	take	time	to	display	or	may	not	be	displayed	correctly.
•	 If	the 	Auto 	Adjust 	operation 	cannot 	optimize 	the 	computer 	signal, 	try 	to 	adjust 	[HORIZONTAL], 	[VERTICAL], 	[CLOCK], 	and 	[PHASE]	
manually. (→ page 116, 117)

❽ 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.	After	 the	cooling	 is	completed,	 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.

2. Projecting an Image (Basic Operation)
 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.
•	 Do	 not	turn	 off	the	 main	 power	 using	the	Main	 Power	 Switch	 or	by	 disconnecting	 the	power	 to	the	 projector	 while	lens	adjust-
ments	 are	being	 performed.	 If	power	 is	removed	 while	the	lens	 is	moving,	 you	may	 not	be	able	 to	achieve	 the	best	 possible	 lens	
adjustments after restarting the projector.

❾ Carrying the Projector
Preparation:	Make	sure	that	the	projector	is	turned	off.
1. Unplug the power cord.
2.	 Disconnect	any	other	cables.
•	 Remove	the	USB	memory	if	it	is	inserted	into	the	projector.
•	 Remove	the	lens	before	shipping	the	projector.
3.  Mount the lens cap on the lens.
4. Before	moving	the	projector, 	screw	in	the	tilt	feet	if	they	have	been	lengthened.
NOTE:
•	 Do	not	apply	strong	shock	or	force	to	the	projector	while	carrying	the	projector.
•	 Remove	the	lens	before	moving	the	projector.	Attach	the	lens	cap	to	the	lens	and	the	dust	cap	to	the	lens	hood	of	the	projector.
•	 Use	the	original	 carton	when	shipping	 the	projector	 without	the	lens.	 Improper	 packaging	 may	cause	 damage	 to	the	 projector	
during shipping.
