1. Introduction
• 10 W built-in speaker for an integrated audio solution
	 Powerful	10	watt	monaural	speaker	provides	volume	need	for	large	rooms.
• The supplied remote control allows you to assign a CONTROL ID to the projector
	 Multiple 	projectors 	can	 be	operated 	separately 	and	 independently 	with 	the	 same 	single	 remote	 control	by	assigning 	
an	ID	number	to	each	projector.
• Vertical keystone correction
	 Keystone	feature	allows	the	projector	to	correct	vertical	distortion.
• USB Display 
	 Using	 a	commercially	 available	USB	cable	 (compatible	 with	USB	 2.0	specifications)	 to	connect	 the	computer	 with	
the	projector	 allows	you	to	send	 your	computer	 screen	image	to	the	 projector	 without	the	need	 of	a	traditional	
computer	cable	(VGA).
•  Integrated RJ-45 connector for wired networking capability along with wireless networking capabilities
	 An	 RJ-45	connector	 is	standard. 	A	 wireless	 LAN	unit	is	equipped	 with	the	projector	 for	models	 distributed	 in	North	
America	 models.	An	 optional	 wireless	 LAN	unit	is	available	 for	models	 for	Europe,	 Australia,	 Asia	and	other	 coun-
tries	than	North	America.
• Software programs (User Supportware) contained in the supplied CD-ROM

• AUTO POWER ON and AUTO POWER OFF features
	 The	 AUTO	POWER	 ON(AC),	 AUTO	POWER	 ON(COMP1),	 AUTO	POWER	 OFF,	and	OFF	 TIMER	 features	 eliminate 	
the	need	to	always	use	the	POWER	button	on	the	remote	control	or	projector	cabinet.
• Preventing unauthorized use of the projector
	 Enhanced	 smart	security	 settings	for	keyword	 protection,	 cabinet	control	panel	lock,	security	 slot,	and	security	
chain	opening	to	help	prevent	unauthorized	access,	adjustments	and	theft	deterrence.

Opening and closing the lens cover
Slide	the	lens	cover	to	the	left	to	uncover	the	lens.
To	cover	the	lens,	slide	the	lens	cover	to	the	right.
NOTE:
•	 The	lens	cover	 works	 in	conjunction	 with	the	AV	mute	 function.	 Closing	the	lens	 cover	 will	turn	 off	the	 image	 and	sound	 during	
normal	projector	operation;	opening	it	will	restore	the	image	and	sound.
	 With	 the	lens	 cover	 closed	 the	image	 and	sound	 is	turned	 off,	however	 the	lamp	 is	still	 lit.	If	the	 projector	 stays	this	way	 for	about	
2	hours,	it	will	turn	off	automatically.
•	 Do	 not	pull	 the	lens	 cover	 with	excessive	 force	or	apply	 strong	 pressure	 in	either	 the	up	or	down	 direction.	 Doing	so	can	 cause	
damage	to	the	lens	cover	sliding	mechanism!

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
1Press	firmly	and	slide	 the	battery	
cover	off.
2Install 	new 	batteries 	(AAA). 	Ensure	
that 	you 	have 	the 	batteries’ 	polarity	
(+/−)	aligned	correctly.
•	 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.
Battery Installation
3Slip	 the	cover	 back	over	the	bat-
teries	 until	it	snaps	 into	place. 	Do	
not	 mix	 different	 types	of	batteries	
or	new	and	old	batteries.
