Installation (continued)
Front projection, ceiling mounting
For ceiling mounting, you need the ceiling mount 
kit designed for this projector. Ask a specialist for 
installation. For details, consult your dealer.
•	 The	warranty	on	this	projector	does	not	cover	any	
damage caused by use of any non-recommended 
ceiling mount kit or installation of the ceiling mount 
kit in an improper location.
•	 When	using	the	projector	mounted	on	the	ceiling,	
set Image Reverse in the Installation menu to Mirror 
Invert. See page 27.
•	 When	the	projector	is	mounted	on	the	ceiling,	
images may appear darker than those projected in 
the case of tabletop mounting. This isn’t a product 
malfunction.
Ceiling mount installation
If you wish to install the projector using a ceiling 
mount, please use the screw holes as the illustration 
shows.
Important:
•	 Screws	are	not	included.	Please	obtain	the	
appropriate screws for your type of ceiling. (M4 
diameter)
•	 It	is	recommended	that	you	keep	a	reasonable	
space between the bracket and the projector to 
allow for proper heat distribution.
Caution:
•	 Installation	must	be	done	by	a	qualified	
professional. 
 When the projector is installed on the ceiling using 
the ceiling mount kit, it is recommended to hold 
the mount kit and the projector using a metal bar 
or wire in addition to the mount kit fixing screws 
to prevent the projector from falling due to an 
earthquake or other cause. For that purpose, use 
a metal bar, wire, or screw that bears a load of at 
least 55 kgf. When using a metal wire, secure one 
end to a screw hole marked with an arrow on the 
rear terminal panel and the other end to the mount 
kit. (Don’t use screw holes without arrow marks.) In 
this case, make sure that the screw is inserted in 
the projector at least 5 mm. The length of the screw 
should	be	20	mm	or	shorter.	Also	make	sure	that	
no electrical current is flowing in the mount kit due 
to current leakage or other cause. 
Rear projection
Ask a specialist for installation. For details, consult 
your dealer.
•	 For	rear	projection,	set	Image	Reverse	in	the	
Installation menu to Mirror. See page 27.
Caution:
•	 Placing	the	projector	directly	on	a	carpet	impairs	
ventilation by the fans, causing damage or failure. 
Put a hard board under the projector to facilitate 
ventilation.
•	 Place	the	projector	at	least	50	cm	(or	20	inch)	away	
from the wall to prevent the intake vents and the 
exhaust vents that emit hot air from being blocked.
•	 Do	not	use	the	projector	in	the	following	locations	
and manners, which may cause fire or electric 
shock.
•	 In	a	dusty	or	humid	place.

2. Plug the power cord in the wall outlet.
3. Remove the lens cap.
Warning:
•	 Do	not	look	into	the	lens	directly	when	the	projector	
is on.
•	 The	lens	cap	is	for	protecting	the	lens.	If	you	leave	
the lens cap on the lens with the projector turned 
on, it may be deformed because of heat build-
up. Remove the lens cap when you turn on the 
projector.
•	 One	of	power	cords	for	the	U.S.,	Europe,	
U.K., Australia, and South Korea is provided 
appropriately.
•	 This	projector	uses	the	power	plug	of	three-pin	
grounding type. Do not remove the grounding pin 
from the power plug. If the power plug doesn’t fit 
your wall outlet, ask an electrician to change the 
wall outlet.
•	 In	case	that	the	power	cord	for	the	U.S.	is	provided	
with this projector, never connect this cord to any 
outlet or power supply using other voltages or 
frequencies than rated. If you want to use a power 
supply using other voltage than rated, prepare an 
appropriate power cord separately.
•	 Use	100-240	V	AC	50/60	Hz	to	prevent	fire	or	
electric shock.
•	 Do	not	place	any	objects	on	the	power	cord	or	
do not place the projector near heat sources to 
prevent damage to the power cord. If the power 
cord should be damaged, contact your dealer for 
replacement because it may cause fire or electric 
shock.
•		 Do	not	modify	or	alter	the	power	cord.	If	the	power	
cord is modified or altered, it may cause fire or 
electric shock.
Caution:
•	 Plug	in	the	power	cord	firmly.	When	unplugging,	
hold and pull the power plug, not the power cord.
•	 Do	not	plug	in	or	out	the	power	cord	with	your	
hand wet. It may cause electric shock.
•	 When	you	move	the	projector,	turn	off	the	power,	
unplug the power cord from the wall outlet, and 
then remove the connected cords. Otherwise, the 
power cord may be damaged, resulting in fire or 
electric shock.
•	 If	dust	or	metallic	substance	is	on	or	around	the	
pins of the power plug, unplug the power cord and 
clean it using a dry cloth. If you continue to use the 
projector without cleaning, it may result in fire or 
electric shock. Clean the power plug periodically at 
least once a year.
•	 Be	sure	to	unplug	the	power	cord	from	the	wall	
outlet if the projector will not be used for a long 
period of time. Otherwise, it may cause fire.
Important:
•	 When	Standby	Mode	of	the	Efficient	Mode	menu	
in the Installation menu is set to LAN, Speaker Out, 
or Monitor Out, the fans rotate at very low speed 
during standby after plugging the power cord (with 
5 second high speed rotation at the beginning) 
and after turning off the lamp. This is to cool down 
the projector operating various functions during 
standby and is not a malfunction. (When Standby 
Mode is set to Low, the fans stop during standby.)
Adjusting the position of the 
projected image
To adjust the position of the projected image on the 
screen, use the LENS SHIFT dial.
1. Rotate the LENS SHIFT dial inside the top cover of 
the projector to adjust the image position.
•	 Rotating	the	dial	clockwise	(or	counterclockwise	
for a ceiling-mount projector) moves the image 
up. 
•	 Rotating	the	dial	counterclockwise	(or	clockwise	
for a ceiling-mount projector) moves the image 
down.
•	 Be	careful	not	to	be	caught	in	the	opening	in	the	
lens while the lens is moving.
•	 While	the	lens	shift	is	working,	the	screen	may	
flicker.
•	 Projected	images	may	become	distorted,	have	
decreased resolution, or have shadows at their 
corners if they are positioned close to the top or 
bottom. 
						

							EN-16
Adjustment of the projection angle
For the best projection, project images on a flat screen 
installed	at	90	degrees	to	the	floor.	If	necessary,	tilt	the	
projector using the two adjustment feet on the bottom 
of the projector.
Using the adjustment feet (front)
1. Tilt up the projector to the appropriate angle.
2. Rotate the adjustment feet (front) for fine 
adjustment.
Important:
•	 Install	the	screen	on	a	flat	wall	at	90	degrees	to	the	
floor.
•	 Slanting	the	projector	more	than	±10°	(right	and	
left)	or	±15°	(front	and	rear)	may	cause	trouble	or	
explosion of the lamp. You can tilt the projector up 
to 8 degrees using the adjustment feet only.
•	 Images	may	not	be	projected	in	a	shape	of	a	
regular rectangle or with its aspect ratio 4:3, 
depending on the installation conditions of the 
projector and the screen.
When projected images are 
distorted to a trapezoid
When Auto Keystone in the Installation menu is set 
to On, this projector automatically corrects vertical 
keystone distortion. For fine adjustment, press the 
KEYSTONE button on the projector or the remote 
control to display Keystone, and adjust the image by 
pressing the ,  button (or VOLUME ,  button 
on the remote control).
In the following cases:
Press the 
 button.
Press the 
 button.
•	 In	the	keystone	adjustment,	you	can	obtain	an	
optimum result when the LENS SHIFT dial is at the 
factory default position. (See page 9.)
•	 The	automatic	keystone	adjustment	may	not	
be carried out correctly because of the ambient 
temperature and the installation conditions of the 
projector and the screen. In such cases, correct the 
keystone manually.
•	 When	the	projector	is	projecting	images	where	
acceleration is present, such as in a vehicle and 
aircraft, the automatic keystone adjustment may 
not function correctly. In such a case, set Auto 
Keystone in the Installation menu to Off and correct 
the keystone manually.
Preparation (continued)
•	 You	can	correct	the	vertical	keystones.	However,	
their adjustment ranges are limited in such 
correction.
Important:
•	 When	the	keystone	adjustment	is	carried	out,	the	
adjustment value is indicated. Note that this value 
doesn’t mean a projection angle.
•	 The	allowable	range	of	the	adjustment	value	in	
the keystone adjustment varies depending on 
the installation condition, input signal and aspect 
settings in MENU.
•	 When	the	keystone	adjustment	takes	effect,	the	
resolution decreases. In addition, stripes may 
appear or straight lines may bend in images with 
complicated patterns. They are not due to product 
malfunctions.
•	 Noise	may	appear	on	the	screen	during	the	
keystone adjustment because of the type of the 
video signal being projected and the setting values 
of the keystone adjustment. In such cases, set the 
keystone adjustment values in the range where the 
image is displayed without noise.
•	 When	the	keystone	adjustment	is	carried	out,	the	
image may not be displayed correctly because of 
the type of input signal.

screen. If the temperature stays high, the lamp will 
go out automatically.
Important:
•	 Do	not	display	a	still	picture	for	a	long	time	
because the afterimages may persist on the screen.
When connecting to a laptop computer:
When this projector is connected to a laptop 
computer, there may be times when images may not 
be projected. When it occurs, set the computer so that 
it can output signals externally. The procedure varies 
across computers in use. See the instruction manual 
of your computer.

Play the field-sequential 3D video contents on a 
computer or DVD player, and then, connect the cable 
with the projector.
Go to the Picture menu (or press the 3D button on 
the remote control) and set the 3D option to On. 
(See page 23.)
Put on the 3D glasses to watch the contents.
If the contents are not projected correctly, go to the 
Picture menu, and switch the 3D Sync Invert option to 
On.
Important:
•	 You	cannot	project	the	3D	content	from	the	input	
source LAN Display, USB Display, and PC Less 
Presentation.
•	 If	the	viewing	distance	is	nearer	than	the	
recommended distance, it will cause physical 
discomfort and eye fatigue.
•	 Watch	the	contents	in	front	of	the	screen,	not	at	big	
angle. If you are viewing the screen at big angle, 
you may not be able to view 3D contents correctly.
•	 If	you	are	not	viewing	3D	contents	correctly,	
check to see if the 3D glasses are powered on or 
adequately charged. See the instruction manual of 
the 3D glasses for more information.
•	 There	are	personal	differences	in	viewing	the	3D	
images. For persons with myopia, hypermetropia, 
astigmatism or left and right sights, please wear 
glasses to correct them then wear the 3D glasses.
•	 The	picture	seems	misplaced	at	the	start	of	
projecting the 3D images, however, this is not a 
malfunction.
•	 With	the	3D	option	set	to	On,	contents	displayed	
on the projector appear darker. It is normal and 
does not mean the projector is malfunctioning.

•	 The	MAGNIFY	mode	cannot	be	used	when	viewing	
3D contents on the projector.
•	 It	may	occur	that	the	image	may	not	be	enough	3D	
image because setting such as fluorescent lighting 
may occur loss of synchronism of glasses.
•	 3D	image	may	not	appear	on	the	screen	depending	
on the PC performance such as graphics board, 
memory, or CPU.
•	 The	signals	specified	in	the	table	on	page	60	
can be displayed with viewing 3D contents on 
the projector. If a different signal is inputted, the 
projector shows no 3D contents even with the 3D 
option set to On in the Picture menu.
•	 If	DVD	is	run	by	480p	signals,	3D	image	may	not	be	
displayed correctly depending on the DVD player.

Caution:
Notes on danger to public health during watching 
3D image
•	 Stop	viewing	the	3D	image	immediately	if	you	feel	
tired, discomfort, or any other abnormality. It may 
cause you to feel unwell if continuing to watch the 
3D image in such cases. Please take the necessary 
rest, do not continue watch the 3D image for a long 
time. Stop using the 3D glasses if you can clearly 
see double images when viewing 3D content. 
Prolonged use may cause eyesight fatigue.
•	 The	following	people	need	to	refrain	from	use	as	
with 2D image.
•	 a	photosensitive	patient
•	 a	patient	with	heart	disease
•	 a	person	in	poor	physical	condition
•	 a	sleepy	person
•	 a	very	tired	person
•	 a	drunk	person
•	 children
•	 When	watching	3D	movies,	take	an	appropriate	
break after watching a movie. When watching 3D 
content on interactive devices such as 3D games 
or computers, take an appropriate break every 
30-60	minutes.	Prolonged	use	may	cause	eyesight	
fatigue.
•	 When	you	feel	uncomfortable,	stop	viewing	
3D images and playing 3D games until you are 
restored. If necessary, consult a doctor. Also, 
stop driving a car until you are restored (for about 
2 hours). The period to restore varies with the 
individual.
•	 As	a	guide,	3D	glasses	should	not	be	used	by	
children younger than 5 - 6 years old. As it is 
difficult to judge younger children’s reactions to 
fatigue or discomfort, their physical condition may 
deteriorate suddenly. When this product is being 
used by a child, the parent or guardian should 
check to ensure that the child’s eyes are not 
becoming tired.
•	 When	viewing	the	pictures	that	roll	over	and	
shake or many dynamic pictures, if you feel 
uncomfortable, please look at another place.
•	 When	viewing	contents	with	movements	such	as	
rotation, or horizontal or vertical oscillation, you 
may feel as if you are actually moving. If such a 
feeling results in discomfort, look away from the 
screen.
•	 When	using	the	3D	glasses,	be	careful	not	to	strike	
the screen or other people by mistake. As the 
images are in 3D, you may mistake the distance 
from the screen, causing to strike the screen which 
may result in injury. When using the 3D glasses, 
do not place breakable objects near the glasses. 
You may move by mistaking the 3D objects you are 
viewing as the real objects, causing damages to 
surrounding objects that may lead to injury.
•	 When	using	the	3D	glasses,	make	sure	your	eyes	
are on an approximate horizontal level. If you 
suffer from myopia (short sightedness), hyperopia 
(far-sightedness), astigmatism, or have eyesight 
differences between the left and right eyes, please 
use corrective glasses or other such methods to 
correct your eyesight before putting on the 3D 
glasses.
•	 When	you	view	the	3D	images,	keep	a	distance	
from the screen of about three times the effective 
height of the screen.
