Setting
This Projector is equipped with 2 Projection Lamps.  This 
function allows you to choose how to use the lamp as follows. 
 Lamp1 ............ Always use Lamp 1.
  Lamp2  ........... Always use Lamp 2.
  Lamp1/2 .........  Automatically switch the active lamp from one  
lamp to the other when the projector is turned 
Off and On each time the lighting time of a 
lamp exceeds 10 hours.
Lamp control
This function allows you to change brightness of the screen.
Auto 1 .........  The brightness according to the input signal 
(between Normal and Eco mode).
Auto 2 .........  The brightness according to the input signal 
(between High and Eco mode).
High ............  Brighter than the Normal mode.
Normal  .......  Normal brightness 
  Eco 1 ..........  
Lower brightness and Fan speed decrease. 
Lower brightness reduces the lamp power 
consumption and extends the lamp life.
 Eco 2 ..........  Lower brightness and Fan speed increase. 
Lower brightness reduces the lamp power 
consumption and extends the lamp life. It is 
recommended to use Eco 2 when using the 
projector continuously over a long period of 
time. 
Lamp control
Lamp life control
Select the lamp operation when the total lighting time of a lamp 
exceeds the recommended total hours of use. 
  
  Mode 1   ............   A lamp can be turned on even after exceeding 
the recommended total hours of use.
  Mode 2   ......  A lamp is not turned on after exceeding the 
recommended total hours of use.
✔Note:
	 •	 	 When	Lamp	1	or	Lamp	2	mode	is	switched	to	Lamp	1/2	
mode,	the	active	lamp	changes	after	the	total	lighting	
time	of	a	currently	used	lamp	exceeds	10	hours.	
	 •		 When	the	total	lighting	time	of	one	lamp	exceeds	the	
recommended	total	hours	of	use	in	the	Lamp	1/2	mode,	
the	Lamp	mode	will	be	switched	to	Lamp	1	or	Lamp	2	
mode	automatically.
	 •	 	 Lamp	mode	cannot	be	changed	for	a	while	after		turning	
on	the	projector.	Lamp	needs	some	time	to	stabilize	
after	the	power	is	turned	on.	Stored	lamp	mode	will	be	
active	after	the	lamp	is	stabilized.
  •	When	the	different	lighting	time	of	the	lamps	light	
alternately,	you	may	recognize	different	brightness	and	
white	balance	on	each	different	lighting	time	of	lamps.
	 	 When	you	change	the	other	lamp,	we	recommend	you	 always	use	the	other	lamp	which	is	not	changed.

Maintenance and Care
Filter Instructions
Filter prevents dust from accumulating on the optical elements inside the projector\
. Should the filter becomes 
clogged with dust particles, it will reduce cooling fans’ effectiveness and may result in internal heat buildup 
and adversely affect the life of the projector. This projector has an electrically operated filter which helps you to 
replace the filter easily. The projector monitors the condition of the filter at all time and replac\
es a filter with a 
new one automatically when it detects the clogging. 
If the projector reaches a time set in the timer setting (p. 
59), a Filter replacement icon (Fig.1) appears on the screen 
and the WARNING FILTER indicator on the top panel lights 
up (p.75). When you see this icon, replace the filter as 
soon as possible (p53).  If the filter is out of scroll and the 
projector reaches a time set in the timer setting, Fig. 2 
appears on the screen, indicating that the filter cartridge 
replacement is necessary.
When the filter scroll is counted down to 1, the Last scroll 
icon (Fig.3) appears on the screen, indicating that there is 
one scroll left in the filter cartridge (p.59).
If the projector detects that the filter is clogged and no scroll 
is left in the filter cartridge, a Filter cartridge replacement 
icon (Fig. 4) appears on the screen and the WARNING 
FILTER indicator on the top panel lights up (p.75). When you 
see this icon, replace the filter cartridge (p.61) and reset the 
Filter counter (p.62) and the Scroll counter (p.62).
When the filter is being scrolled by the Filter control function 
in the setting menu (p.53), a Filter replacement icon and 
“Please wait...” message (Fig.5) appear on the screen 
and the WARNING FILTER indicator blinks slow (approx. 2 
seconds ON, 2 seconds OFF) (p.73).
The WARNING FILTER indicator blinks fast when the 
projector detects an abnormal condition, the filter cartridge 
is not installed properly, or the filter scroll is not working 
properly (p.75).

projector	will	be	shut	down	automatically	for	safety	purposes.
•		Do	not	forget	to	reset	the	filter	counter	and	the	scroll	counter	 in	the	setting	menu	after	replacing	the	filter	cartridge.	If	you	
forget	to	reset	the	filter	counter	and	the	scroll	counter,	the	
projector	cannot	recognize	the	correct	number	of	remaining	
scrolls	and	it	may	cause	a	breakdown.	
•		 When	the	projector	is	kept	used	for	3	minutes	without	getting	
the	filter	cartridge	replaced	after	the	Fig.4	appears	on	the	
screen,	the	projector	is	turned	off	automatically	to	prevent	the	
damage	of	optical	components.
