Filter prevents dust from accumulating on the optical elements inside th\
e projector. Should the Filter  become 
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. If a “Filter warning” icon appears on the screen, replace the Fi\
lter   
immediately. Replace the filter by following the steps below.
Loosen the screw and remove the lamp cover and lift 
the filter out of the projector.3

CAUTION
-  Do not operate the projector with the filter removed. 
Dust may accumulate on the optical elements 
degrading picture quality.
-  Do not put anything into the air vents. Doing so may 
result in malfunction of the projector.
-  Do not wash the filter with water or any other liquid 
matter. Otherwise the filter may be damaged.
RECOMMENDATION
 We recommend avoiding dusty/smoky environments 
when you operate the projector  . Usage in these 
environments may cause poor image quality  .
 When using the projector under dusty or smoky conditions, 
dust may accumulate on a lens or optical elements inside 
the projector degrading the quality of a projected image. 
When the symptoms above are noticed, contact your 
authorized dealer or service center for proper cleaning.

Cleaning the Projector Cabinet
Cleaning the Projection Window
Unplug the AC power cord before cleaning.
First, remove the dust with a commercially available air 
blower. Then gently wipe the projection window surface. 
Use a cleaning paper moistened with methyl alcohol 
(methanol). Avoid using an excessive amount of cleaner.
Do not use abrasive cleaners, solvents, or other harsh 
chemical cleaners to avoid damaging the projection window.
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.
Maintenance and Cleaning
CAUTION
Do not use any flammable solvents or air sprays 
on the projector and in its vicinity. The explosion 
or fire hazard may occur even after the AC power 
cord is unplugged because the temperature inside 
the projector is extremely high due to the lamps. In 
addition, there is a risk that the internal parts may 
be damaged not only by the flammable air spray but 
also by the cold air.
CAUTION
This projector is equipped with a projection window.
-  Do not rub the projection window with a hard fiber 
cloth or hit it with a something hard to prevent the 
projection window from scratching. 
-  Do not use a chemical cleaner (liquid and solid) to 
avoid deteriorating the projection window.

When the projection lamp of the projector reaches its end 
of life, the Lamp replacement icon appears on the screen 
and LAMP REPLACE indicator lights yellow. Replace the 
lamp with a new one promptly. The timing when the LAMP 
REPLACE indicator should light is depending on the lamp 
mode.
For continued safety, replace with a lamp of the 
same type. Do not drop a lamp or touch a glass 
bulb! The glass can shatter and may cause injury.
Allow a projector to cool for at least one hour 
before you open the Lamp Cover. The inside of

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 life may differ from lamp to lamp and according to the environment of use. There is no guarantee
  of the same life for each lamp. Some lamps may fail or terminate their\
 life in a shorter period of time than 
  other similar lamps.
 If the projector indicates that the lamp should be replaced, i.e., if t\
he 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 t\
his manual.) Continuous use of 
  the lamp with the LAMP REPLACE indicator lighted may increase the risk of lamp explosion.  
 A Lamp may explode as a result of vibration, shock or degradation as a re\
sult 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 SAFETY PRECAUTIONS SHOULD BE TAKEN .
If a lamp explodes, disconnect the projector’s AC plug from the AC outlet immediately. Contact an 
authorized service center for a checkup of the unit and replacement of t\
he lamp. Additionally, check 
carefully to ensure that there are no broken shards or pieces of glass a\
round 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 t\
he 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.
