    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  “2-6  Correcting  Keystone 
    Distortion” (→ page 22).
    - 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	projector.
    	
    Zoom
    Turn	the	zoom	lever	or	zoom	ring	clockwise	and	counterclockwise.
    -	 The	separately	sold	NP11FL	lens	does	not	have	a	zoom	ring.

     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	GEOMETRIC. 	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	GEOMETRIC.	button	for	a	minimum	of	2	seconds.
    •	 Each	time	the	GEOMETRIC.	 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	32.
    •	 The	 Cornerstone	 adjustment	will	not	be	available	 during	the	Keystone	 adjustment.	 To	perform	 the	Cornerstone	 adjustment,	press	
    and	hold	 the	GEOMETRIC.	 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	
    GEOMETRIC.	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	GEOMETRIC. 	but-
    ton to display the Keystone screen and repeat above steps 1 to 6.
