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.

Remote Jack
NOTE: 
•	 When	a	remote	cable	is	inserted	into	the	REMOTE	jack,	the	remote	control	does	not	work	for	infrared	wireless	communication.
•	 When	a	remote 	cable 	is 	inserted 	into 	the 	REMOTE 	jack, 	the 	[POWER-SA VING] 	and 	[NORMAL2] 	functions 	in 	[ST ANDBY 	MODE] 	
will not work.
•	 Power	will	not 	be 	supplied 	to 	the 	remote 	control 	from 	the 	projector 	via 	the 	REMOTE 	jack. 	Batter y 	is 	needed 	when 	the 	remote 	
control is used in wired operation.

❷ Connecting Your Computer/Connecting the supplied Power 
Cord
NOTE:
•	 Install	a	lens	before	performing	the	following	steps.	(→ page 162)
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 164.
	 Connect	the	computer 	cab le 	(V GA) 	betw een 	the 	projector’ s 	COMPUTER 	1 	IN 	connector 	and 	the 	computer’ s 	por t 	
(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 	T O 	 RAIN 	 OR 	 MOISTURE.
DO	NOT	USE 	THIS 	UNIT’S 	PLUG 	WITH 	AN 	EXTENSION 	CORD 	OR 	IN 	AN 	OUTLET 	UNLESS 	ALL 	THE 	PR ONGS	
CAN	BE	FULLY	INSERTED.
	 Important	Information:
•	 When	plugging	in 	or 	unplugging 	the 	supplied 	po wer 	cord, 	mak e 	sure 	that 	the 	main 	po wer 	s witch 	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 	po wer 	cord’ s 	three-pin 	plug 	to 	the 	A C 	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 	ma y 	become 	tempor arily 	heated 	if 	the 	projector 	is 	tur ned 	off 	with 	the 	PO WER 	b utton 	or 	if 	the 	
AC	power	supply	is	disconnected	during	normal	projector	operation.
Use	caution	when	picking	up	the	projector.

Using the Supplied Power Cord Stopper
To	prevent	the 	po wer 	cord 	from 	accidently 	remo ving 	from 	the 	A C 	IN 	of 	the 	projector , 	attach 	the 	supplied 	po wer 	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
•	 To	prevent	the 	po wer 	cord 	from 	coming 	loose , 	mak e 	sure 	that 	all 	the 	prongs 	of 	the 	po wer 	cord 	are 	fully 	inser ted 	
into	the	AC 	IN 	ter minal 	of 	the 	projector 	bef ore 	using 	the 	po wer 	cord 	stopper 	to 	fix 	the 	po wer 	cord.	A 	loose 	
contact	of	the	power	cord	may	cause	a	fire	or	electric	shock.
•	 Do	not	bundle	the	power	cord.	Doing 	 this 	 could 	 cause 	 heat 	 or 	 a 	 fire.
•	 Do	not	clamp 	tw o 	po wer 	cords 	that 	w ould 	be 	used 	when 	stac king 	tw o 	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 loc k it.
