Cleaning the Air Filter

When the message that prompts cleaning the air
filter appears, clean the air filter.
If the dust cannot be removed from the air filter
even after cleaning, replace the air filter with a
new one.
For details on a new air filter, consult with qualified
Sony personnel.
Caution
If you continue to use the projector even after the
message is displayed, dust may accumulate, clogging it.
As a result, the temperature may rise inside the unit,
leading to a possible malfunction or fire.

power cord from a wall outlet.
