This projector is equipped with a lamp to project images. This lamp is a consumable. It may burn out or its brightness 
may decrease during use. In such cases, replace the lamp with a new one as soon as possible. Be sure to replace the 
lamp with a new lamp sold separately that is exclusive to this projector. Contact your dealer for purchase of the lamp.
Spare lampVLT-HC7800LP
Warning:
•	 Be	careful	not	to	drop	the	lamp	fixing	screws	inside	of	the	projector.	Don’t	put	a	metal	piece	or	flammable	object	
into the projector. Using the projector with any foreign object present inside may result in electric shock or fire. 
When you can’t remove the foreign object from the inside, contact your dealer for removal.
•	 Do	not	touch	the	lamp	with	bare	hands	or	give	a	shock	to	the	lamp.	Attach	the	lamp	properly.	Improper	handling	
may cause explosion.
•	 Be	sure	to	install	the	lamp	securely.	When	the	lamp	isn’t	installed	properly,	it	won’t	illuminate.	Improper	installation	
may also result in fire.
•	 Don’t	shake	the	removed	lamp	or	don’t	lift	it	above	your	face.	Your	eyes	may	be	injured	by	flying	or	falling	glass	
fragments.
•	 Don’t	replace	the	lamp	immediately	after	use	because	the	lamp	cover	will	be	very	hot.	You	may	get	burned.	Turn	
off the power using the POWER button. After the lamp goes out, wait about \
two minutes until the intake and 
exhaust fans for cooling the lamp stop rotating. Then unplug the power cord, and wait at least one hour to allow 
the lamp to cool down enough to the touch.
•	 Keep	small	parts	such	as	screws	out	of	the	reach	of	babies	and	children.	If	swallowed,	those	parts	can	cause	
suffocation. In case a baby or a child swallows them, see a doctor.
Interval of lamp replacement
The recommended interval of lamp replacement is about 5000 hours*1*2 of consecutive use. Such interval differs 
depending on the operating environment and may be shorter than 5000 hours*1*2. Decrease in luminescence and/or 
color brightness indicates that the lamp needs to be replaced. When the lamp operation time exceeds 3750 hours*1, 
the	indicator	will	blink	alternately	between	green	and	red	(while	the	lamp	is	lit;	when	the	lamp	is	not	lit,	the	indicator	
will be lit red only) and the lamp replacement message will appear on the screen for one minute everytime the lamp is 
turned on. When the lamp has been used for about 4750 hours*1, the replacement message (LAMP REPLACEMENT) 
will appear on the screen for one minute every 25 hours*1 thereafter. When the lamp operation time exceeds 5000 
hours*1*2, the projector automatically shuts off and can’t be used until the lamp is replaced and the lamp 
operation time is reset.
*1: Duration when LAMP MODE of the INSTALLATION menu is set to LOW. When it is set to STANDARD, this duration will be 
shorted.
*2: When LAMP MODE is set to STANDARD, this duration will be shorted to 3000 hours.
Caution:
•	 Don’t	remove	the	lamp	for	any	purpose	other	than	replacement.	Unnecessary	removal	of	the	lamp	may	result	in	a	
breakdown.
•	 This	projector	uses	a	high-pressure	mercury	lamp	as	the	light	source.	The	high-pressure	mercury	lamp	may	
explode or fail to illuminate permanently because of an impact, scratch,\
 or deterioration through use. The period 
of time until explosion or permanent failure to illuminate varies considerably from lamp to lamp, depending on 
operation conditions. Therefore, the lamp may explode soon after the start of use.
•	 The	possibility	of	explosion	of	the	lamp	increases	if	you	use	it	beyond	its	replacement	period.	When	the	instruction	
of lamp replacement appears, replace it with a new one immediately even if the lamp is still lighting \
normally.
•	 When	the	high-pressure	mercury	lamp	explodes,	glass	fragments	will	scatter	inside	or	outside	the	lamp	box	and 	
the gas charged inside the lamp will diffuse inside or outside the projector. The gas inside the lamp contains 
mercury. Be careful not to breathe it or avoid it from entering your eye or mouth. If you should breathe it or if it 
should enter your eye or mouth, see a doctor immediately.
•	 In	the	event	that	the	high-pressure	mercury	lamp	exploded,	glass	fragments	may	have	been	scattered	inside	the	
projector. Ask your dealer to replace the lamp and to inspect the inside of the projector. When you clean or replace 
the lamp by yourself, be sure to hold the handle of the lamp. You may get injured by glass fragments.
•	 When	removing	the	lamp	from	the	ceiling-mounted	projector,	use	the	lamp	replacement	attachment	packed	with	
the projector or option lamp to prevent glass fragments from scattering.
•	 Be	sure	to	use	the	lamp	exclusive	to	this	projector,	VLT-HC7800LP.	Use	of	other	lamps	may	cause	a	failure	of	the	
projector.
