8. Maintenance
❶ Cleaning the Lens
•	 Turn	off	the	projector	before	cleaning.
•	 The	projector	has	a	plastic	lens.	Use	a	commercially	available	plastic	lens	cleaner .
•	 Do	not	scratch	or	mar	the	lens	surface	as	a	plastic	lens	is	easily	scratched.
•	 Never	use	alcohol	or	glass	lens	cleaner	as	doing	so	will	cause	damage	to	the	plastic	lens	surface.
 WARNING
•	 Do	not	use	a	spray	containing	flammable	gas	to	remov e	dust	attached	to	the	lens,	etc.	Doing	so	may	result	in	
fire. 
						

							114
❷ Cleaning the Cabinet
Turn	off	the	projector,	and	unplug	the	projector	before	cleaning.
•	 Use	a	dry	soft	cloth	to	wipe	dust	off	the	cabinet.
	 If	heavily	soiled,	use	a	mild	detergent.	
•	 Never	use	strong	detergents	or	solvents	such	as	alcohol	or	thinner.	
•	 When	cleaning	the	ventilation	slits	or	the	speaker	using	a	vacuum	cleaner,	do	not	force	the	brush	of	the	vacuum	
cleaner	into	the	slits	of	the	cabinet.
Vacuum	the	dust	off	the	ventilation	slits	or	the	speaker.
•	 Poor	ventilation	caused	by	dust	accumulation	in	ventilation	openings	can	result	in	overheating	and	malfunction.	
These	areas	should	be	cleaned	regularly.
•	 Do	not	scratch	or	hit	the	cabinet	with	your	fingers	or	any	hard	objects
•	 Contact	your	dealer	for	cleaning	the	inside	of	the	projector.
NOTE:	Do	not	apply	volatile	agent	such	as	insecticide	on	the	cabinet,	the	lens,	or	the	screen.	Do	not	leave	a	rubber	or	vinyl	product	
in	prolonged	contact	with	it.	Otherwise	the	surface	finish	will	be	deteriorated	or	the	coating	may	be	stripped	off.

Over-Temperature	Protection
If	the	projector	inside	temperature	gets	too	high,	the	light	modules	will	be	turned	off	automatically	and	the	status	
indicator	will	start	to	blink	(2-cycle	On	and	OFF).
Should	this	happen,	do	the	following:
•	 Unplug	the	power	cord	after	the	cooling	fans	stop.
•	 Move	the	projector	to	a	cooler	location	if	the	room	where	you	are	presenting	is	particularly	too	warm.
•	 Clean	the	vents	if	they	are	clogged	with	dust.
•	 Wait	about	60	minutes	until	the	inside	of	the	projector	becomes	cool	enough.

Common Problems & Solutions
(→	“POWER/STATUS/LIGHT	Indicator”	on	page	115.)
ProblemCheck	These	Items
Does not turn on
or shut down•	 Check	that	the	power	cord	is	plugged	in	and	that	the	power	button	on	the	projector	cabinet	or	the	remote	control is on� (→ pages 11, 12)•	 Check	to	see	if	the	projector	has	overheated.	If	there	is	insufficient	ventilation	around	the	projector	or	if	the	room where you are presenting is particularly warm, move the projector t\
o a cooler location�•	 The	light	module	may	fail	to	light.	Wait	a	full	minute	and	then	turn	on	the	power	again.•	 Set	[FAN	MODE]	to	[HIGH]	when	using	the	projector	at	altitudes	approximately	5500	feet/1700	meters	or higher� Using the projector at altitudes approximately 5500 feet/1700 meters or\
 higher without setting to [HIGH] can cause the projector to overheat and the projector could shut down� If this happens, wait a couple minutes and turn on the projector� (→ page 58) If you turn on the projector immediately after the light module is turne\
d off, the fans run without displaying an image for some time and then the projector will display the image� Wait for a moment�•	 In	case	it’s	hard	to	think	the	trouble	is	not	caused	on	the	above	mentioned	conditions,	unplug	the	power	cord from the outlet� Then wait 5 minutes before plugging it in again� (→ page 24)
Will turn off
•	 Ensure	that	the	[OFF	TIMER]	or	[AUTO	POWER	OFF]	is	off.	(→ page 52, 61)
No picture
•	 Check	if	the	appropriate	input	is	selected.	(→ page 14) If there is still no picture, press the SOURCE button or one of the source buttons again�•	 Ensure	your	cables	are	connected	properly.•	 Use	menus	to	adjust	the	brightness	and	contrast.	(→ page 45)•	 Check	that	the	AV	MUTE	(image	off)	buttons	are	not	pressed.•	 Reset	the	settings	or	adjustments	to	factory	preset	levels	using	the	[RESET]	in	the	Menu.	(→ page 66)•	 Enter	your	registered	keyword	if	the	Security	function	is	enabled.	(→ page 30)•	 If	the	HDMI	1	IN	or	the	HDMI	2	IN	signal	cannot	be	displayed,	try	the	following.- Reinstall your driver for the graphics card built in your computer, or use the updated driver� For reinstalling or updating your driver, refer to the user guide accompanied with your computer or graphics card, or contact the support center for your computer manufactu\
rer� Install the updated driver or OS on your own responsibility� We are not liable for any trouble and failure caused by this installation\
�•	 Signals	may	not	be	supported	depending	on	the	HDBaseT	transmission	device.	IR	and	RS232C	cannot	be	used in certain cases as well�•	 Be	sure	to	connect	the	projector	and	notebook	PC	while	the	projector	is	in	standby	mode	and	before	turning	on the power to the notebook PC� In most cases the output signal from the notebook PC is not turned on un\
less connected to the projector before being powered up�*	 If	the	screen	goes	blank	while	using	your	remote	control,	it	may	be	the	result	of	the	computer’s	screen-saver or power management software�•	 See	also	the	next page�
Picture suddenly 
becomes dark•	 Check	if	the	projector	is	in	the	Forced	ECO	mode	because	of	too	high	ambient	temperature.	If	this	is	the	case, lower the internal temperature of the projector by selecting [HIGH\
] for [FAN MODE]� (→ page 58)
Color tone or hue is 
unusual
•	 Check	if	an	appropriate	color	is	selected	in	[WALL	COLOR].	If	so,	select	an	appropriate	option.	(→ page 
51)
•	 Adjust	[HUE]	in	[PICTURE].	(→ page 45)
Image	isn’t	square	to	the screen•	 Reposition	the	projector	to	improve	its	angle	to	the	screen.	(→ page 16)•	 Use	the	Keystone	correction	function	to	correct	the	trapezoid	distortion.	(→ page 21)
Picture is blurred
•	 Adjust	the	focus.	(→ page 19)•	 Reposition	the	projector	to	improve	its	angle	to	the	screen.	(→ page 16)•	 Ensure	that	the	distance	between	the	projector	and	screen	is	within	the	adjustment	range	of	the	lens.	(→ 
page 67)
•	 Has	the	lens	been	shifted	by	an	amount	exceeding	the	guaranteed	range?	(→ page 71)•	 Condensation	may	form	on	the	lens	if	the	projector	is	cold,	brought	into	a	warm	place	and	is	then	turned	on� Should this happen, let the projector stand until there is no condensat\
ion on the lens�
Image is scrolling 
vertically, horizontally 
or both•	 Check	the	computer’s	resolution	and	frequency.	Make	sure	that	the	resolution	you	are	trying	to	display	is	supported by the projector� (→ page 126)•	 Adjust	the	computer	image	manually	with	the	[HORIZONTAL]/[VER TICAL]	in	the	[IMAGE	OPTIONS].	(→ 
page 47)
