Cleaning the Air Filter
Cleaning the Air Filter
When a message appears on the projected image indicating time for a filter cleaning, 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.
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.

the AC power cord from the AC outlet.

Open the rear panel by loosening the
three screws on the rear panel.
