Maintenance/replacement
Before performing maintenance/replacement
 fMake sure to turn of f the power before maintaining or replacing the unit. ( x pages 54, 63)
 fWhen switching of

f the projector, make sure to follow the procedures in “Switching off the projector” 
(x
  page   63).
Maintenance
Outer case
Wipe off dirt and dust with a soft, dry cloth.
 fIf the dirt is persistent, soak the cloth with water and wring it thorou\
ghly before wiping. Dry of

f the projector with 
a dry cloth.
 f Do not use benzene, thinner

, or rubbing alcohol, other solvents, or household cleaners. Doing so may 
deteriorate the outer case.
 f When using chemically treated dust cloths, follow the instructions writt\
en on its packaging.
Lens front surface
Wipe off dirt and dust from the front surface of the lens with a soft clean clo\
th.
 fDo not use a cloth that is fluf

fy, dusty, or soaked with oil/water.
 fSince the lens is fragile, do not use excessive force when wiping the lens.
Attention
 f The lens is made of glass. Impacts or excessive force when wiping may scratch its surface. Handle with care.
Air filter unit
Perform maintenance of the air filter unit in the following cases.
 fThe air filter is clogged with dust, causing the filter replacement message to appear on the screen and the filter 
indicator  to light in red.
Attention
 f Make sure to turn of f the power before performing maintenance on the air filter unit. fMake sure that the projector is stable, and perform the maintenance in a safe place even if you drop it accidentally .

Attention
 fAfter washing the air filter unit, dry it thoroughly before attaching it back to the projector .  Attaching a wet unit will cause an electric shock or 
malfunction.
 f Do not disassemble the air filter unit. fT

ake care not to touch the air intake fan in the air filter unit compartment when removing dirt or dust.
Note
 f Make sure that the air filter unit is properly attached before using the projector . If it is not properly attached, the projector will suck in dirt and 
dust causing a malfunction.
 f If you use the projector without attaching the air filter unit, the filter indicator  blinks in red and the message appears on the 
projected image for approximately 30 seconds.
 f Replace the air filter unit with the new optional Replacement Filter Unit (Model No.: ET-

EMF330) if it is damaged or if the dirt does not come 
off even after washing.
 f Air filter replacement is recommended after cleaning the unit two times. fThe dust-proof properties may be reduced after each cleaning.
