Maintenance	and	Cleaning
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 Filter immediately. Replace the filter by following the steps below.
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, LCD panels, 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.
Be sure to reset the Filter counter after cleaning or replacing the filter.

Cleaning	the	Projector	Cabinet
Cleaning	the	Projection	Lens
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.
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.
When moving this projector or while not using it over an extended period of time, attach the lens cap.
Attach the lens cap according to the following procedures.

Thread the string through the hole on the lens cap and then tie a knot in the string to secure it in place.
To pass the other end of the string into the hole on the bottom of the projector and pull at it.
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.

Maintenance	and	Cleaning
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 lamp\
s.
●  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  this  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  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 bei\
ng 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 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.
