2. Installation and Connections
Connecting to a Network
The projector comes standard with a LAN port () which provides a LAN connection using a LAN cable. 
Using a LAN cable allows you to specify the Network Settings and the Alert Mail Settings for the projector over a 
LAN.	 To	use	 a	LAN	 connection,	 you	are	required	 to	assign	 an	IP	address	 to	the	 projector	 on	the	 [PROJECTOR	
NETWORK	SETTINGS]	screen	of	the	web	browser	on	your	computer.	For	setting,	see	page	43 , 44, 45 , 46.

2. Installation and Connections
Connecting the Supplied Power Cord
Connect the supplied power cord to the projector.
First connect the supplied power cord's two-pin plug to the AC IN of the projector, and then connect the other plug 
of the supplied power cord in the wall outlet.
When  you  press  the  Main  Power  switch  to  the  On  position  (I),    the  projector  will  go  into  standby  mode.  When  in 
standby	mode,	the	POWER	indicator	will	light	orange	and	the	STATUS	indicator	will	light	green	to	show	that	[Normal]	
mode	is	selected	for	[Standby	mode].
Make sure that the prongs are fully inserted into 
both the a C in and the wall outlet.

3. Projecting an Image (Basic Operation)
This section describes how to turn on the projector and to project a picture onto the screen.
  Turning on the Projector
N OTE:
•	 The	projector	has	two	power	switches:	a	main	power	switch	and	a	POWER	(	
	)	button.
•	 When	 plugging	 in	or	 unplugging	 the	supplied	 power	cord,	make	 sure	that	the	main	 power	 switch	 is	pushed	 to	the	 off	(
 )	
po -
sition.	Failure	to	do	so	may	cause	damage	to	the	projector.
1.  To turn on the main power to the projector, press the 
Main Power switch to the on position ( I ).
•	 T h e	 p r o j e c t o r	 w i l l	g o	i n t o	 s t a n d b y	 m o d e .	W h e n	i n	
standby  mode,  the  POWER  indicator  will  light  orange 
and  the  STATUS  indicator  will  light  green  to  show  that 
[Normal]	mode	is	selected	for	[Standby	mode].
3.  Press the POWER (
) button on the projector cabi-
net or the POWER (
) button on the remote control 
for about 1 second.
  The STATUS indicator goes off and the POWER indica-
tor starts blinking. 
  When  the  POWER  indicator  turns  a  steady  green,  and 
the projector is ready to use.
  Less  than  4  seconds*  after  turning  on  the  power,  the 
projector is ready to display PC or video images (Quick 
Start).The	 quick	start	time	is	only	 when	 [Standby	 mode]	
is	set	to	[Normal]	in	the	on-screen	message.
  If  the  projector  is  turned  off  and  is  turned  it  back  on 
quickly, it may take some time to start displaying an im-
age. This is because the fans run for cooling purpose.
TIP:   When  the  STATUS  indicator  lights  orange,  it  means  that 
the	[Key	lock]	is	turned	on.	See	page	6 2.
•	 When 	the 	message 	"Projector 	is 	locked! 	Enter 	your 	password."	
is	 displayed,	 it	means	 that	the	[Password]	 is	turned	 on.	See	
page 40.
  After  you  turn  on  your  projector,  ensure  that  the  com-
puter  or  video  source  is  turned  on  and  that  your  lens 
cover is removed.

Note on Startup screen (Menu Language Select screen)
When you first turn on the projector, you will get the Startup menu. This menu gives you the opportunity to select 
one of the 21 menu languages.
To select a menu language, follow these steps:
1.  Use the    or  button to select one of the 21 
languages for the menu.
2.  Press the OK button to execute the selection.
After  this  has  been  done,  you  can  proceed  to  the  menu  op-
eration.
If  you  want,  you  can  select  the  menu  language  later.  See 
[Language]	on	pages	49 and 60 .
NOTE:	Immediately	 after	turning	 on	the	 projector,	 screen	flicker	may	occur.	 This	is	normal.	 Wait	3	to	 5	minutes	 until	the	lamp	
lighting	is	stabilized.
NOTE: If you turn on the projector immediately after the lamp is turned off or when the temperature is high, the fans runs with-
out displaying an image for some time and then the projector will display the image.
When the Lamp mode is set to Quiet, the LAMP indicator will light green.
If one of the following things happens, the projector will not turn on.
•	 If	 the	internal	 temperature	 of	the	 projector	 is	too	 high,	 the	projector	 will	not	turn	 on	to	protect	 the	internal	 system.	
Please wait for the projector's internal components to cool down.
•	 When	the	lamp	reaches	its	end	of	usable	life,	the	projector	will	not	turn	on.	If	this	happens,	replace	the	lamp.
•	 If	 the	lamp	 fails	to	light,	 and	if	the	 STATUS	 indicator	 flashes	on	and	 off	in	a	cycle	 of	six	 times,	 wait	a	full	 minute	
and then turn on the power.
NOTE:	Turning	the	Main	Power	Switch	Off	then	Back	On
Allow	
a	minimum	of	1	second	between	turning	off	the	main	power	switch	and	turning	it	back	on	again.
The	same	will	be	applied	when	a	power	strip	equipped	with	a	switch	and	a	breaker	is	used.
Failing	to	do	so	could	result	in	no	power	to	the	projector.	(There	will	be	no	stand-by	LED)
Should this happen, unplug the power cord and plug it in again. Turn on the main power switch.
CAUTION:
The projector cannot be turned off for 60 seconds after the lamp is turned on and while the POWER indicator 
is blinking green. Doing so could cause premature lamp failure.

Adjusting the Tilt Foot
1.  Lift the front edge of the projector.
CAUTION:
Do not try to touch the ventilation outlet during Tilt Foot adjustment 
as it can become heated while the projector is turned on and during 
its cool down period after it is turned off.
2.   Push straight up and hold the Adjustable Tilt Foot Lever on the 
front of the projector to extend the adjustable tilt foot.
3.   Lower the front of the projector to the desired height.
4.   Release the Adjustable Tilt Foot Lever to lock the Adjustable tilt 
foot.
  t he tilt foot can be extended up to 1.8 inch/45 mm.
  t here is approximately 10 degrees (up) of adjustment for the front 
of the projector.
  r otate the rear foot to the desired height in order to square the im-
age on the projection surface.
CAUTION:
•	 Do 	not 	use 	the 	tilt-foot 	for 	purposes 	other 	than 	originally 	intended.
  Misuses such as using the tilt foot to carry or hang (from the wall 
or ceiling) the projector can cause damage to the projector.
Adjusting the left and right tilt of an image [Rear foot]
1.  Remove the spacer (black rubber) from the rear foot.
  a spacer is provided for leveling the projector. Keep the spacer for  future use.
2.  Rotate the rear foot.
  t he rear foot can be extended up to 0.4 inch/10 mm. r otating the 
rear foot allows the projector to be placed horizontally.
N OTE:
•	 Do	 not	extend	 the	rear	 foot	 beyond	 its	height	 limit	(0.4	inch/10	 mm).	Doing	
so may cause the rear foot to come out of the projector. 
•	 After	using	the	projector,	attach	the	spacer	to	the	rear	foot.

N OTE:
•	 Vertical	distortions	between	offset	angles	of	+/-	30	degrees	can	be	corrected.
	 The	range	of	keystone	correction	is	not	the	maximum	tilt	angle	of	projector.
•	 The	Auto	Keystone	correction	will	take	effect	in	2	seconds	after	changing	the	projection	angle	during	projection.
•	 The	left	and	right	(horizontal)	keystone	correction	is	not	available.
