CORNERSTONE
Display	the	4-point	correction	screen	and	adjust	the	trapezoidal	distortion	of	the	projection	screen.
Please	refer	to	“Correcting	 Horizontal	and	Vertical	 Keystone	 Distortion	 [CORNERSTONE]” 	(→	page	33)	 for	 details	
on	the	operation.
HORIZONTAL	CORNER/VERTICAL	CORNER
Distortion	correction	for	corner	projection	such	as	wall	surfaces.
HORIZONTAL CORNER
 ������������������������������Performs correction for projection onto a wall lying at an angle to the hor\
izontal direction�
*  Reverse angle correction is also possible�
VERTICAL CORNER
 ������������������������������Performs correction for projection onto a wall lying at an angle to the ver\
tical direction�
*  Reverse angle correction is also possible�
NOTE:
•	 When	 the	maximum	 adjustment	 range	is	exceeded,	 distortion	adjustment	 is	disabled.	 Set	up	the	 projector	 at	an	 optimal	 angle	as	
the deterioration in the image quality increases as the distortion adjus\
tment volume gets larger.
•	 Please	 note	that	the	image	 will	go	out	 of	focus	 due	to	the	 difference	 in	the	 distance	 between	 the	upper	 and	lower	 or	left	 and	 right	
sides 	and 	the 	center 	of 	the 	screen 	for 	projections 	cutting 	across 	corners. 	Lenses 	with 	short 	focal 	points 	are 	also 	not 	recommended	
for projections cutting across corners as the image will go out of focus\

Conditions for using tiling
All	the	projectors	need	to	fulfil	the	following	conditions.
•	 The	panel	size	must	be	the	same
•	 The	projection	screen	size	must	be	the	same
•	 The	left	and	right	ends	or	top	and	bottom	ends	of	the	projection	screen	must	be	consistent.

•	 The	settings	for	the	top	and	bottom	edges	of	the	edge	blending	are	the	same
If	the	 tiling	 conditions	 are	satisfied,	 the	video	 screen	 of	the	 projector	 at	each	 installation	 position	will	be	automatically	
extracted	and	projected.
If	the	 tiling	 conditions	 are	not	satisfied,	 adjust	the	video	 screen	 of	the	 projector	 at	each	 installation	 position	using	the	
zoom	function.

This	reorients	 your	image	 for	your	 type	of	projection. 	The	 options	 are:	desktop	 front	projection,	 ceiling	rear	projection,	
desktop	rear	projection,	and	ceiling	front	projection.
NOTE: 
•	 Please	 consult	the	retail	 store	 if	you	 require	 special	installation	 services	e.g.	when	 mounting	 the	projector	 to	a	ceiling.	 Never	install	
the projector on your own. This may result in the projector falling down\
 and causing injury to people.
•	 When	 using	the	projector	 suspended	 from	a	ceiling,	 ensure	that	people	 do	not	 stay	 below	 the	projector.	 In	the	 event	 the	lamp	
were to break, there is a risk that glass fragments may fall from the pr\
ojector.

This	function	allows	for	quick	adaptive	color	correction	in	applications	where	the	screen	material	is	not	white.
NOTE:	Selecting	[WHITEBOARD]	reduces	lamp	brightness.
Selecting Fan Mode [FAN MODE]
Fan	Mode	is	used	to	set	the	speed	of	the	internal	cooling	fan.
MODE  ��������������������Select three modes for fan speed: AUTO, HIGH, and HIGH ALTITUDE�
AUTO: The built-in fans automatically run at a variable speed according \
to the internal temperature�
HIGH: The built-in fans run at high speed
HIGH ALTITUDE: The built-in fans run at a high speed� Select this option when using the projector at altitudes 
approximately 5500 feet/1600 meters or higher � To use the projector with ECO MODE ON in other installed 
conditions than desktop/ceiling with +/-20°, heed the following:
(1) Select [HIGH ALTITUDE]  for [MODE] at altitude 3200 feet/1000 meters�
(2) Select [OFF] for [ECO MODE] at altitude 6800 feet/2100 meters or h\
igher �
NOTE: 
•	 Make	sure	the	speed	is	set	to	[HIGH]	when	you	are	using	this	device	continuously	for	several	days.
•		 Set	[FAN	MODE]	to	[HIGH	ALTITUDE]	when	using	the	projector	at	altitudes	approximately	5500	feet/1600	meters	or	higher.
•	 Using	the	projector	 at	altitudes	 approximately	 5500	feet/1600	 meters	or	higher	 without	 setting	to	[HIGH	 ALTITUDE]	 can	cause	
the projector to overheat and the protector could shut down. If this hap\
pens, wait a couple minutes and turn on the projector.
•		 Using	 the	projector	 at	altitudes	 less	than	 approximately	 5500	feet/1600	 meters	and	setting	 to	[HIGH	 ALTITUDE]	 can	cause	 the	
lamp	to	overcool,	causing	the	image	to	flicker.	Switch	[FAN	MODE]	to	[AUTO].
•		 Using	 the	projector	 at	altitudes	 approximately	 5500	feet/1600	 meters	or	higher	 can	shorten	 the	life	of	optical	 components	 such	
as the lamp.
•	 Your	setting	will	not	be	affected	even	when	[RESET]	is	done	from	the	menu.
TIP: 
•	 When	[HIGH	ALTITUDE]	is	selected	for	[FAN	MODE],	a	symbol	icon	 will be displayed at the bottom of the menu.
