You should clean the projector if it becomes dirty or if the quality of
projected images starts to deteriorate.

Cleaning the Projector's Surface

Clean  the  projector's  surface  by  wiping  it  gently  with  a  soft  cloth.
If  the  projector  is  particularly  dirty,  moisten  the  cloth  with  water
containing  a  small  amount  of  neutral  detergent,  and  then  firmly  wring
the  cloth  dry  before  using  it  to  wipe  the  projector's  surface.

Attention

Do not use volatile substances such as wax, alcohol, or thinner to clean the
projector's surface. The quality of the case may change or become discolored.

Cleaning the Lens

Use a commercially available cloth for cleaning classes to gently wipe
the lens.

Attention

Do not rub the lens with harsh materials or subject the lens to shocks, as it
can easily become damaged.

Cleaning the Air filter

Clean the air filter and the Air intake vent when the following message
is displayed.

The projector is overheating. Make sure nothing is blocking the air
vent, and clean or replace the air filter.

Attention

•

If  dust  collects  on  the  air  filter  it  can  cause  the  internal  temperature  of
the  projector  to  rise,  and  this  can  lead  to  problems  with  operation  and
shorten  the  optical  engine's  service  life.  Clean  the  air  filter  immediately
when  the  message  is  displayed.

•

Do not rinse the air filter in water. Do not use detergents or solvents.

• If a message is frequently displayed, even after cleaning, it is

time to replace the air filter. Replace it with a new air filter.

• It is recommended that you clean these parts at least once every

three months. Clean them more often than this if using the
projector in a particularly dusty environment.
