    and	the	lens	shift	mechanism	may	encounter	damage	caused	by	improper	handling	during	transportation. 	
    Do	not	hold	the	lens	part	when	carrying	the	projector.
    Doing	so	could	cause	the	focus	ring	to	rotate,	resulting	in	accidental	dropping	of	the	projector.
    Lamp Replacement
    •	 To	replace	the	lamp,	follow	all	instructions	provided	on	page	79.
    •	 Be	sure	to	replace	 the	lamp	 when	 the	message	[THE LAMP HAS REACHED THE END OF ITS USABLE LIFE. 
    PLEASE REPLACE THE LAMP.]	appears. 	If	 you	 continue	 to	use	 the	lamp	 after	the	lamp	 has	reached	 the	end	
    of	its	usable	life,	the	lamp	bulb	may	shatter,	and	pieces	of	glass	may	be	scattered	in	the	lamp	case. 	Do	not	touch	
    them	as	the	pieces	of	glass	may	cause	injury.
    	 If	this	happens,	contact	your	dealer	for	lamp	replacement.
    A Lamp Characteristic
    The	projector	has	a	high-pressure	mercury	lamp	as	a	light	source.
    A	lamp	 has	a	characteristic	 that	its	brightness	 gradually	decreases	 with	age.	Also	 repeatedly	 turning	the	lamp	 on	
    and	off	will	increase	the	possibility	of	its	lower	brightness.
    CAUTION:
    When	 removing	 the	lamp	 from	a	ceiling-mounted	 projector,	make	sure	that	no	one	 is	under	 the	projector. 	Glass	
    fragments	could	fall	if	the	lamp	has	been	burned	out.
    Important Information
    Remote Control Precautions

    •	 If	the	remote	control	gets	wet,	wipe	it	dry	immediately.
    •	 Avoid	excessive	heat	and	humidity.
    •	 Do	not	heat,	take	apart,	or	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.
    Note for US Residents
    The	lamp	in	this	product	contains	mercury. 	Please	dispose	according	to	Local,	State	or	Federal	Laws.
    CAUTION
    •	Always carry	your	projector	by	the	carrying	handle.	Before	doing	so,	be	sure	to	lock	the	carrying	handle	in	place.
    	 To	lock	the	carrying	handle,	see	“To	lock	the	carrying	handle”	on	page	6.
    •	 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.
    •	 Do	 not	send	 the	projector	 in	a	soft	 case	 by	parcel	 delivery	 service	or	cargo	 shipment. 	The	 projector	 inside	the	
    soft	case	could	be	damaged.
    •	 Select	 [HIGH]	in	Fan	 mode	 if	you	 continue	 to	use	 the	projector	 for	consecutive	 days.	(From	 the	menu,	 select	
    [SETUP]	→	[OPTIONS(1)]	→	[FAN	MODE]	→	[HIGH].)
    •	 Before	 using	Direct	 Power	 Off,	be	sure	 to	allow	 at	least	 20	minutes	 immediately	 after	turning	 on	the	 projector	
    and	starting	to	display	an	image. 	
    •	 Do	not	unplug	the	power	cable	from	the	wall	outlet	or	projector	when	the	projector	is	powered	on. 	Doing	so	can	
    cause	damage	to	the	AC	IN	connector	of	the	projector	and	(or)	the	prong	plug	of	the	power	cable.
    	 To	turn	off	the	 AC	power	 supply	 when	the	projector	 is	powered	 on,	use	 a	power	 strip	equipped	 with	a	switch	
    and	a	breaker.
    •	 Do	 not	try	to	touch	 the	ventilation	 outlet	on	the	 left	front	 (when	 seen	from	the	front)	 as	it	can	 become	 heated	
    while	the	projector	is	turned	on	and	immediately	after	the	projector	is	turned	off.
    •	 Do	not	turn	 off	the	 AC	power	 for	60	seconds	 after	the	lamp	 is	turned	 on	and	 while	 the	POWER	 indicator	 is	
    blinking	green. 	Doing	so	could	cause	premature	lamp	failure.
