 Replacing the Lamp and the Filters
When	the	lamp	 reaches	 the	end	 of	its	 life,	 the	LAMP	 indicator	 in	the	 cabinet	 will	blink	 red	and	 the	message	 “THE	
LAMP	HAS	REACHED	 THE	END	 OF	ITS	 USABLE	 LIFE.	PLEASE	 REPLACE	 THE	LAMP	 AND	FILTER. 	USE	 THE	
SPECIFIED	 LAMP	FOR	SAFETY	 AND	PERFORMANCE.” 	will	 appear	 (*).	Even	 though	 the	lamp	 may	still	be	working,	
replace	 the	lamp	 to	maintain	 the	optimal	 projector	 performance. 	After	 replacing	 the	lamp,	 be	sure	 to	clear	 the	lamp	
hour	meter. 	(→	page	116)
 CAUTION
•	 DO	NOT	TOUCH	 THE	LAMP	 immediately	 after	it	has	 been	 used.	It	 will	 be	extremely	 hot.	Turn	 the	projector	
off	and	then	disconnect	the	power	cord. 	Allow	at	least	one	hour	for	the	lamp	to	cool	before	handling.
•	 Use	the	specified	lamp	for	safety	and	performance.
•	 DO	NOT	REMOVE	 ANY	SCREWS	 except	one	lamp	 cover	 screw	 and	two	lamp	 housing	 screws.	You	 could	 receive	
an	electric	shock.
•	 Do	not	break	the	glass	on	the	lamp	housing.
	 Keep	 finger	prints	off	the	 glass	 surface	 on	the	 lamp	 housing. 	Leaving	 finger	prints	on	the	 glass	 surface	 might	cause	
an	unwanted	shadow	and	poor	picture	quality.
•	 The	 projector	 will	turn	 off	and	 go	into	 standby	 mode	when	you	continue	 to	use	 the	projector	 for	another	 100	hours	
after	 the	lamp	 has	reached	 the	end	 of	its	 life. 	If	 this	 happens,	 be	sure	 to	replace	 the	lamp. 	If	 you	 continue	 to	use	
the	 lamp	 after	the	lamp	 reaches	 the	end	 of	its	 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	NEC	
dealer	for	lamp	replacement.
*NOTE:	This	message	will	be	displayed	under	the	following	conditions:
•	 for	one	minute	after	the	projector	has	been	powered	on
•	 when	the		(POWER)	button	on	the	projector	cabinet	or	the	POWER	OFF	button	on	the	remote	control	is	pressed
To	turn	off	the	message,	press	any	button	on	the	projector	cabinet	or	the	remote	control.
