Maintenance
Before cleaning the projector / 
replacing components
Attention
Turn off the  switch and disconnect 
 
z
the power plug from the wall outlet before cleaning the 
projector/replacing components.
Follow the “Switching off the power” procedure when 
 
z
turning off the projector. (

Cleaning the projector
 
■ Cleaning the outer surface of the 
projector
Wipe off dirt and dust gently with a soft dry cloth.
If it is difficult to remove the dirt, soak a cloth in water, 
 
z
wring the cloth well and then wipe the projector. Dry 
the projector with a dry cloth.
Do not use petroleum benzene, thinner, any 
 
z
alcoholic solvent, or kitchen detergents. Using these 
substances may result in changes or damage to the 
surface of the projector.
When using a chemically treated cloth, follow the 
 
z
accompanying guidelines.
 
■ Cleaning the lens surface
If dirt or dust accumulates on the surface of the lens, it will 
be enlarged and projected onto the screen.
 
Wipe dirt and dust from the front of the lens gently with a 
clean, soft, and dry cloth.
Do not use a fluffy rag, or a greasy, wet, or dirty 
 
z
cloth.
Do not rub the lens harshly as this may damage the 
 
z
surface.
Attention
The lens is made of glass. It may break or crack if struck 
 
z
with a hard object or rubbed harshly. Please be careful 
when handling the lamp.
 
■ Air filter unit
If too much dust accumulates in the air filter the internal 
temperature of the projector cannot be maintained at the 
normal level. A confirmation message is displayed on the 
screen, and at the same time  illuminates red. The 
power is cut off automatically after a while. Clean the filter 
after every 100 hours of usage.
Remove the air filter cover.

Component replacement
 
■ Air filter and 
electrostatic filter
The air filter should be replaced when cleaning is ineffective.   
A replacement air filter / electrostatic filter is available separately (service component).    
Contact your dealer for the optional air filter and electrostatic filter . 
 Also, please replace the air filter and electrostatic filter when replacing the lamp unit.   
 (An air filter and electrostatic filter are included with the [ET -LAA110] replacement lamp unit.)
 
■ Lamp unit
The lamp unit is a consumable component. See “When to replace the lamp unit” ( page 76) about the lifespan.
Contact your dealer if you wish to purchase a replacement lamp unit (ET -LAA110: Service component).
It is recommended that specialized engineers perform lamp unit replacement. Contact your dealer .
Attention
Wait until the lamp unit has cooled sufficiently before replacing (wait one hour or longer). 
 
z
The lamp cover gets very hot, and contact with it can cause burns.
 
Before replacing the lamp unit
 
■
A Phillips screwdriver is necessary when carrying out  
z
replacement. Hold the screwdriver firmly.
The light source lamp is a glass component. If it is hit on a hard 
 
z
object or dropped, breakage may occur. 
Be careful when handling a light source lamp.
Do not disassemble or modify the lamp unit.
 
z
Grip the handle when you remove the lamp unit. Some parts of  
z
the lamp unit are sharpened and may cause injury.
The lamp may be ruptured. Care should be taken not to scatter 
 
z
pieces of the broken lamp glass when replacing the lamp unit. 
Pieces of the broken lamp may fall from the lamp unit especially 
when the projector is mounted on the ceiling, so when replacing 
the lamp unit do not stand directly underneath it or position your 
face close to it. 
The lamp contains mercury. Contact the local government office 
 
z
or distributor for the correct disposal of the old lamp unit.
Note
Be sure to use the lamp unit specified.

■ When to replace the lamp unit
The lamp unit is a consumable component. Brightness decreases according to duration of usage, so periodical replacement 
of the lamp unit is necessary. A rough estimate for the usage period is 2 000 hours, but depending on the characteristics of 
individual lamps, usage conditions, periods of continuous use, and environmental conditions etc., the lamp may cease to 
illuminate prior to reaching 2 000 hours of use. It is recommended that you prepare a spare lamp unit in advance.
 
As the risk of the lamp to cracking increases after 2 000 hours the lamp automatically turns of f.
