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. 
62), a Filter replacement icon (Fig.1) appears on the screen 
and the WARNING FILTER indicator on the top panel lights 
up (p.79). When you see this icon, replace the filter as soon 
as possible (pp.35, 57). 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.62).
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.79). When you 
see this icon, replace the filter cartridge (p.64) and reset the 
Filter counter (p.65) and the Scroll counter (p.65).
When the filter is being scrolled using the remote control 
unit (p.35) or the Filter control function in the setting 
menu (p.57), 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.77).
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.79).

Maintenance and Care 
						

							68
This projector uses a high-pressure lamp which must be handled carefully and properly. 
Improper handling may result in accidents, injury, or create a fire hazard.
● Lamp  lifetime  may  differ  from  lamp  to  lamp  and  according  to  the  environment  of  use. There  is  no 
guarantee  of  the  same  lifetime  for  each  lamp.  Some  lamps  may  fail  or  terminate  their  lifetime  in  a 
shorter period of time than other similar lamps.
● If  the  projector  indicates  that  the  lamp  should  be  replaced,  i.e.,  if  the  LAMP  REPLACE  indicator  lights 
up,  replace  the  lamp  with  a  new  one  IMMEDIATELY  after  the  projector  has  cooled  down.  (Follow 
carefully the instructions in the Lamp Replacement section of this manual.) Continuous use of the lamp 
with the LAMP REPLACE indicator lighted may increase the risk of lamp explosion.  
● Lamp  may  explode  as  a  result  of  vibration,  shock  or  degradation  as  a  result  of  hours  of  use  as  its 
lifetime  draws  to  an  end.  Risk  of  explosion  may  differ  according  to  the  environment  or  conditions  in 
which the projector and lamp are being used.
IF A LAMP EXPLODES, THE FOLLOWING SAFET y PRECAUTIONS SHOULD BE TAKEN .
If  a  lamp  explodes,  disconnect  the  projector’s  AC  plug  from  the  AC  outlet  immediately.  Contact  an 
authorized  service  station  for  a  checkup  of  the  unit  and  replacement  of  the  lamp.  Additionally,  check 
carefully to ensure that there are no broken shards or pieces of glass around the projector or coming out 
from  the  cooling  air  circulation  holes.  Any  broken  shards  found  should  be  cleaned  up  carefully.  No  one 
should  check  the  inside  of  the  projector  except  those  who  are  authorized  trained  technicians  and  who 
are familiar with projector service. Inappropriate attempts to service the unit by anyone, especially those 
who are not appropriately trained to do so, may result in an accident or injury caused by pieces of broken 
glass.
         LAMP HANDLING PRECAUTIONS
Maintenance and Care
CAUTION 
						

							69
Unplug the AC power cord before cleaning.
Gently wipe the projection lens with a cleaning cloth that 
contains a small amount of non-abrasive camera lens 
cleaner, or use a lens cleaning paper or commercially 
available air blower to clean the lens. 
Avoid using an excessive amount of cleaner. Abrasive 
cleaners, solvents, or other harsh chemicals might scratch 
the surface of the lens.
Cleaning the Projector Cabinet
Unplug the AC power cord before cleaning.
Gently wipe the projector body with a soft dry cleaning 
cloth. When the cabinet is heavily soiled, use a small amount 
of mild detergent and finish with a soft dry cleaning cloth. 
Avoid using an excessive amount of cleaner. Abrasive 
cleaners, solvents, or other harsh chemicals might scratch 
the surface of the cabinet.
When the projector is not in use, put the projector in 
an appropriate carrying case to protect it from dust and 
scratches.

The WARNING indicators show the state of the function which protects the projector. Check the state of the 
WARNING indicators and the POWER indicator to take proper maintenance. 
Warning Indicators
The projector is shut down and the WARNING TEMP. 
indicator is blinking red.
When the temperature inside the projector reaches a 
certain level, the projector will be automatically shut down 
to protect the inside of the projector. The LAMP/SHUTTER 
indicator turns red and the WARNING TEMP indicator 
blinks while the projector is being cooled down. When the 
projector has cooled down enough (to its normal operating 
temperature), it can be turned on again by pressing the 
POWER button.
✔Note:
 
•	 The	 WARNING	 TEMP.	indicator	continues	to	blink	even	after	the	
temperature	inside	the	projector	returns	to	normal.	 When	the	
projector	is	turned	on	again,	the	 WARNING	TEMP.	indicator	stops	
blinking.	
Then check the matters below:
–   Did you provide appropriate space for the projector to be 
ventilated? Check the installing condition to see if the air 
vents of the projector are not blocked.
–   Has the projector been installed near an Air-Conditioning/ 
Heating Duct or Vent? Move the installation of the 
projector away from the duct or vent.
–   Is the filter clean? Replace the filter with a new one.
The projector is shut down; and the LAMP/SHUTTER indicator 
is lighting red and other four indicators are blinking.
When the projector detects an abnormal condition, it will 
be automatically shut down to protect the inside of the 
projector and the LAMP/SHUTTER indicator lights red and 
other four indicators blink. In this case, unplug the AC power 
cord and plug it, and then turn on the projector once again 
to verify operation. If the projector cannot be turned on and 
these indicators are still lighting and blinking, unplug the AC 
power cord and contact the service station.
WARNING
DO NOT LEAVE THE PROJECTOR WITH THE 
AC POWER CORD CONNECTED UNDER AN 
ABNORMAL CONDITION. IT MAY RESULT IN FIRE 
OR ELECTRIC SHOCK.
