2. Projecting an Image (Basic Operation)
❺ Adjusting the Picture Size and Position
Use	the	lens	 shift	dial,	the	adjustable	 tilt	foot	 lever,	 the	zoom	 lever/zoom	 ring	and	the	focus	 ring	to	adjust	 the	picture	
size	and	position.
In	this	chapter	drawings	and	cables	are	omitted	for	clarity.

2. Projecting an Image (Basic Operation)
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.

•	 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	vertical	 shift	adjustment	 must	be	finished	 with	an	image	 shifted	 upward.	 If	you	 finish	 the	vertical	 shift	adjustment	 with	an	
image shifted down, the zoom/focus adjustments or strong shaking may cau\
se a projected image to slightly shift down.
•	 The	lens	shift	function	cannot	be	used	when	using	the	separately	sold	NP11FL	lens.

•	 The	diagram	 below	shows	 the	lens	 shift	 adjustment	 range	for	the	 PA622U	 and	PA522U	 (projection	 mode:	desktop	 front).	To	raise	
the projection position higher than this, use the tilt feet. (→ page 23)

Applicable lens: NP11FL
With	the	NP11FL	lens,	adjust	the	focus	and	picture	distortion.
Preparations:
Turn	the	lens	shift	dials	(vertical	and	horizontal)	on	the	projector	to	return	the	lens	shift	to	the	center.

 knob is horizontal�
From this position, turn the dial 2 full turns counterclockwise�
1.   Turn the distortion ring to the left edge.

3.  Use  the  distortion  ring  to  correct  the  screen’s  distor-
tion.
	 (This	also	brings	the	edges	of	the	screen	into	focus.)
4.  Use  the  focus  lever  to  adjust  the  screen’s  overall  fo-
cus.
*	 If	 the	focus	 at	the	 center	 of	the	 screen	 is	off,	 turn	 the	
distortion	 ring	a	little	 counterclockwise. 	The	 focus	 at	the	
center	 of	the	 screen	 can	now	 be	adjusted	 with	the	focus	
lever.

2. Projecting an Image (Basic Operation)
Adjusting the Tilt Feet
1.  Turn the left and right tilt feet to adjust.
	 The	tilt	feet	lengthen	and	shorten	when	turned.
	 The	 height	of	the	 projected	 image	is	adjusted	 by	turning	 the	left	and	
right	tilt	feet.
	 If	 the	projected	 image	is	tilted,	 turn	one	of	the	 tilt	feet	 to	adjust	 the	
image	so	that	it	is	level.
•	 If	the	projected	 image	is	distorted,	 see	“3-6	 Correcting	 Horizontal	
and	Vertical	 Keystone	 Distortion	 [CORNERSTONE]” 	(→	page	33) 
and	 “[GEOMETRIC	CORRECTION]” 	(→	page	87).
•	 The	tilt	feet	can	be	lengthened	by	a	maximum	of	20	mm.
•	 The	tilt	feet	can	be	used	to	tilt	the	projector	by	a	maximum	of	4º.
NOTE:
•	 Do	not	lengthen	 the	tilt	feet	 any	more	 than	20	mm/0.8".	 Doing	so	will	 make	 the	
tilt	feet’s	 mount	 section	 unstable	 and	could	 cause	 the	tilt	feet	 to	come	 off	the	
projector.
•	 Do	 not	use	 the	tilt	feet	 for	any	 purpose	 other	than	adjusting	 the	projector’s	
projection angle.
	 Handling	 the	tilt	feet	 improperly,	 such	as	carrying	 the	projector	 by	grasping	 the	
tilt feet or hooking it onto a wall using the tilt feet, could damage the projec -
tor.
 
Zoom
Turn	the	zoom	lever	or	zoom	ring	clockwise	and	counterclockwise.
•	 The	separately	sold	NP11FL	lens	does	not	have	a	zoom	ring.

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 78, 79)
❼ Turning Up or Down Volume
Sound	level	from	the	speaker	can	be	adjusted.
TIP:	 When	 no	menus	 appear,	 the	◀ and ▶ buttons on the projector cabinet work 
as a volume control. 
NOTE:
•	 Volume 	control 	is 	not 	available 	with 	the 	◀ or  ▶ button when an image is enlarged 
by	using	the	D-ZOOM	(+)	button	or	when	the	menu	is	displayed.

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	go	off	and	 the	power	 supply	 will	be	cut. 	At	
this	 point,	 if	there	 are	no	input	 signals,	 the	projector	 will	go	
into	 the	standby	 mode	after	about	 10	seconds. 	When	 in	
standby	 mode,	the	POWER	 indicator	 will	light	 red	and	 the	
STATUS	 indicator	 will	light	 off	when	 [NORMAL]	 is	selected	
for	[STANDBY	MODE]. 	
Power On
Steady blue light Standby
Steady red light
Press twice
 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.
•	 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	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.
