    2.	 Adjust	the	focus	at	the	edges	of	the	projected	image.	(Manual 	 focus)
     Turn the edge focus ring clockwise or counterclockwise.
    Optical axis
    This	completes	adjusting	the	projected	image’s	overall	focus.
    NOTE:
    The	NP31ZL	supports	the	Lens	Memory	function,	which	allows	you	to	store	changes	for	Lens	Shift,	Zoom,	and	Focus.
    If	you	accidentally 	move 	the 	Edge 	focus 	ring 	(drawing 	shown 	below) 	after 	having 	stored 	adjusted 	values, 	the 	adjusted 	values 	stored 	
    in	the	Lens	Memory	will	not	be	correctly	applied.
    Edge focus ring
    After	having	removed 	the 	lens 	from 	the 	projector 	and 	mounted 	it 	back, 	call 	up 	the 	adjusted 	values 	stored 	in 	the 	Lens 	Memor y 	and 	
    then	follow	Step	2	in	the	procedure	above	to	adjust	the	focus	at	the	edges	of	the	projected	image	again.
    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 104)
    •	 You	can	also	use	the	TEST	button	on	the	remote	control	to	display	the	test	pattern.
    3.	Keep	pressing	the	FOCUS	−	button	until	the	grid	of	the	text	pattern	is	made	invisible.
    4.	Keep	pressing	the	FOCUS	+	button	until	you	obtain	the	best	focus.
     If you adjust beyond the best focal point, go back to step 3 and repeat \
    the procedures.
    5.	Turn	the	edge	focus	ring	clockwise	or	counterclockwise	to	adjust	the	focus	at	the	edges	of	the	projected	image.

    Adjusting the Tilt Feet
    •		 Turn	the	left 	and 	right 	tilt 	f eet 	on 	the 	right,	left,	and 	rear 	to 	adjust.
    	 The	tilt	feet	lengthen	and	shorten	when	turned.
    	 The	height	of 	the 	pr ojected 	ima ge 	is 	adjusted 	b y 	turning 	the 	left 	
    and	right	tilt	feet.
    	 If	the	pr ojected 	ima ge 	is 	tilted,	turn 	one 	of 	the 	tilt 	f eet 	to 	adjust 	
    the image so that it is level.
    -	 If	the	projected 	image 	is 	distor ted, 	see 	“2-6 	Correcting 	K eystone 	
    Distortion” (→ page 30).
    - The tilt feet can be used to tilt +/− 50 mm/1.97" (6.75°), −9 mm/0.35" 
    (1.2°).
     CAUTION
    The	rear	vents 	of 	the 	projector 	ma y 	become 	heated 	dur ing 	nor mal 	
    projector	operation.
    Use	caution	when	adjusting	the	tilt	foot	on	the	rear	side.	
    NOTE:
    •	 Do	not	lengthen 	the 	tilt 	feet 	on 	the 	right 	and 	left 	any 	more 	than 	50 	mm/1.97" 	
    and	the	tilt 	foot 	on 	the 	rear 	any 	more 	than 	9 	mm/0.35" 	on 	the 	rear . 	The 	for ce 	
    of doing so may cause the rear foot to come off, resulting in damage to 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 th\
    e projector.

    The	following	procedure 	e xplains 	ho w 	to 	use 	the 	[KEYST ONE] 	screen 	from 	the 	men u 	to 	correct 	tr apezoidal 	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 	Hor izontal 	option 	of 	the 	K eystone 	men u 	
    so	that	the	top	and	bottom	of	sides	of	the	projected	image	are	parallel.
    1.	 Press	the	3D 	REFORM 	b utton 	on 	the 	remote 	contr ol 	or 	the 	pr ojector 	
    cabinet.
     The Keystone screen will be displayed on the screen.
    2. Press the ▼	button	to 	select 	[VER TICAL] 	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 	[HORIZONT AL] 	and 	then 	use 	the 	◀ or ▶ 
    so	that 	the 	top 	and 	bottom 	sides 	of 	the 	pr ojected 	ima ge 	are 	parallel.
    •	 Adjust	the	horizontal	keystone	distortion.

    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	39.
    •	 The	Cornerstone 	adjustment 	will 	not 	be 	available 	during 	the 	Keystone 	adjustment. 	T o 	per form 	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. 	T o 	per form 	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	K eystone 	correction 	again, 	press 	the 	3D 	REFORM 	b utton 	
    to display the Keystone screen and repeat above steps 1 to 6.

    INGS-	SESSION	0.000[g-CO2]]	message	will	appear.
    2.	 Secondly,	press 	the 	ENTER 	b utton 	or 	press 	the 	 
    (POWER)	or	the	POWER	OFF	button	again.
     The lamp will turn off and 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].

     CAUTION:
    Parts	of 	the 	projector 	ma y 	become 	tempor arily 	heated 	if 	the 	projector 	is 	tur ned 	off 	with 	the 	PO WER 	b utton 	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. 	T o 	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.
