Remote Control Precautions
•	 Handle	the	remote	control	carefully.
•	 If	the	remote	control	gets	wet,	wipe	it	dry	immediately.
•	 Avoid	excessive	heat	and	humidity.
•	 Do	not	short,	heat,	or	take	apart	batteries.
•	 Do	not	throw	batteries	into	fire.
•	 If	you	will	not	be	using	the	remote	control	for	a	long	time,	remove	the	batteries.
•	 Ensure	that	you	have	the	batteries’	polarity	(+/−)	aligned	correctly.
•	 Do	not	use	new	and	old	batteries	together,	or	use	different	types	of	batteries	together.
•		 Dispose	of	used	batteries	according	to	your	local	regulations.

Operating Range for Wireless Remote Control
•	 The	
infrared	 signal	operates	 by	line-of-sight	 up	to	a	distance	 of	about	 22	feet/7	 m	and	 within	 a	60-degree	 angle	of	
the	remote	sensor	on	the	projector	cabinet.
•	 The	 projector	 will	not	 respond	 if	there	 are	objects	 between	 the	remote	 control	and	the	sensor,	 or	if	strong	 light	falls	
on	the	sensor. 	Weak	batteries	will	also	prevent	the	remote	control	from	properly	operating	the	projector.
1Press 	the 	catch 	and 	remove	
the	battery	cover.
2Install 	new 	ones 	(AA). 	Ensure	
that	 you	have	 the	batteries’ 	polar-
ity	(+/−)	aligned	correctly.
3Slip	 the	cover	 back	over	the	batteries	 until	it	
snaps	into	place.
NOTE:  Do  not  mix  different  types  of  batteries  or 
new and old batteries.

Image	Express	Utility	2.0•	 This	is 	a 	software 	program 	used 	to 	send 	the 	screens 	of 	your 	personal 	comput-
ers	to	the	projector	via	wired/wireless	LAN	(Meeting	mode).
	 Projected	images	can	be	transferred	and	saved	to	personal	computers.
	 When	 “Meeting	 Mode”	is	 used,	 projected	 images	can	be	sent	 and	saved	 to	
the	personal	 computers. 	Images	 can	be	sent	 from	 a	personal	 computer	 to	
not	only	 one	projector	 but	also	 to	two	 or	more	 projectors	 at	the	 same	 time.	
(→	page	183)
PC	Control	Utility	Pro	4This	is	a	software	 program	used	to	operate	 the	projector	 from	the	computer	 when	
the	computer	 and	the	projector	 are	connected	 with	LAN	 (wired	 or	wireless)	 or	
a	serial	cable. 	(→	page	194)
Image	Express	Utility	for	Mac•	 This	is 	a 	software 	program 	used 	to 	send 	the 	Mac’s 	screen 	image 	to 	the 	projec-
tor	 over	 a	network	 (wired	or	wireless	 LAN).	For	 Mac’s	 operating	 environment,	
see	page	195.

the	signal	 can	be	performed. 	It	 is	 also	 possible	 to	send	 an	image	 to	the	 projector	
and	 register	 it	as	 the	 background	 logo.	Once	 the	image	 is	registered,	 it	can	 be	
locked	to	prevent	the	logo	from	being	overwritten.	(→	page	199)

2. Projecting an Image (Basic Operation)
 Connecting Your Computer/Connecting the Power Cord
NOTE:
•	 Install	a	lens	before	performing	the	following	steps.	(→ page 154)
1.	 Connect	your	computer	to	the	projector.
 This  section  will  show  you  a  basic  connection  to  a  computer.  For  information  about  other  connections,  see “(2) 
Making Connections” on page 156.
	 Connect	 the	computer	 cable	(VGA)	 between	 the	projector’s	 COMPUTER	 1	IN	 connector	 and	the	computer’s	 port	
(mini	D-Sub	15	Pin). 	Turn	two	thumb	screws	of	both	connectors	to	fix	the	computer	cable	(VGA).
2.	 Connect	the	supplied	power	cord	to	the	projector.
WARNING:	TO	PREVENT	FIRE	OR	SHOCK,	DO	NOT	EXPOSE	 THIS	UNIT	TO	RAIN	OR	MOISTURE.
DO	NOT 	USE 	THIS 	UNIT’S 	PLUG 	WITH 	AN 	EXTENSION 	CORD 	OR 	IN 	AN 	OUTLET 	UNLESS 	ALL 	THE 	PRONGS	
CAN	BE	FULLY	INSERTED.
	 Important	Information:
•	 When	 plugging	in	or	 unplugging	 the	supplied	 power	cord,	make	 sure	that	the	main	 power	 switch	 is	pushed	 to	
the off [O] position. Failure to do so may cause damage to the projector.
•	 Do	not	use	a	three-phase	power	supply. 	Doing	so	may	cause	malfunction.
	 First	connect	 the	supplied	 power	cord’s	three-pin	 plug	to	the	 AC	IN	of	the	 projector,	 and	then	 connect	 the	other	
plug of the supplied power cord in the wall outlet.
COMPUTER 1 IN
Make sure that the prongs are fully inserted into 
both	the	AC	IN	and	the	wall	outlet.
Main power switch
To wall outlet
NOTE	(for	North	America	only)
•	 The	model	distributed	in	North	America	comes	with	two	different	types	of	power	cords:	one	for	120V	and	the	other	for	200V.
	 Use	the	power	cord	suitable	for	the	voltage	being	used.
 
 CAUTION:
Parts	 of	the	 projector	 may	become	 temporarily	 heated	if	the	 projector	 is	turned	 off	with	 the	POWER	 button	or	if	the	
AC	power	supply	is	disconnected	during	normal	projector	operation.
Use	caution	when	picking	up	the	projector.

2. Projecting an Image (Basic Operation)
Using the Supplied Power Cord Stopper
To	prevent	 the	power	 cord	from	 accidently	 removing	from	the	AC	IN	of	the	 projector,	 attach	the	supplied	 power	cord	
stopper	to	clamp	the	power	cord.
NOTE:
•	 Do	not	clamp	the	power	cord	with	other	cables.	Doing	so	can	generate	noise,	which	can	affect	adversely	the	signal	cable.
 CAUTION
•	 Do	not	bundle	the	power	cord. 	Doing	this	could	cause	heat	or	a	fire.
•	 Do	not	clamp	 two	power	 cords	that	would	 be	used	 when	 stacking	 two	projectors. 	Doing	 this	could	 cause	 a	
fire.
NOTE:	Be	careful	not	to	insert	the	band	inversely.	Once	the	band	is	attached,	it	cannot	be	removed	from	the	slot.
Attaching the power cord stopper
1.	 Insert	the	end	of	band	of	the	power	cord	stopper	into	the	slot	next	to	the	AC	IN	on	the	terminal	panel.
2.	 Use	the	power	cord	stopper	to	clamp	the	power	cord.
 Push the clamper to lock it.

Removing	the	power	cord	from	the	power	cord	stopper
1.	 Push	the	clamper	of	the	power	cord	stopper	to	unclasp	it.
2.	 Push	the	power	cord	clamper	to	open	it	wide	enough	to	pull	out	the	power	cord.

2. Projecting an Image (Basic Operation)
 Turning on the Projector
NOTE:
•	 The	projector	has	two	power	switches:	A	main	power	switch	and	a	POWER	button	(POWER	ON	and	OFF	on	the	remote	control)
•	Turning	on	the	projector:
1.	 Press	the	main	power	switch	to	the	ON	position	(I).
  The projector will go into standby mode.
2.	 Press	the	POWER	button	.
 The projector will become ready to use.
•	Turning	off	the	projector:
1.	 Press	the	POWER	button.
  The confirmation message will be displayed.
2.	 Press	the	POWER	button	again.
 The projector will go into standby mode.
3.	 Press	the	main	power	switch	to	the	OFF	position	(O).
 The projector will be turned off.
 
Remove	the	lens	cap.
1.	 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 STA -
TUS indicator will light green when [NORMAL] is selected 
for	 [STANDBY	 MODE].	See	 the	Power	 Indicator	 section.
