7. Maintenance

This section describes the simple maintenance procedures you should follow to clean the filters, the lens, the cabinet,
and to replace the lamp and the filters.
❶ Cleaning the Filters
The air-filter sponge keeps dust and dirt from getting inside the projector and should be frequently cleaned. If the filter
is dirty or clogged, your projector may overheat.
NOTE: The message for filter cleaning will be displayed for one minute after the projector is turned on or off. When the message is
displayed, clean the filters. The time to clean the filters is set to [OFF] at time of shipment. (→ page 122)
To cancel the message, press any button on the projector cabinet or the remote control.
CAUTION
• Before cleaning the filters, turn off the projector, disconnect the power cord and then allow the cabinet to cool.
Failure to do so can result in electric shock or burn injuries.
Preparation: Before cleaning the filters, use a vacuum cleaner to clean the ventilations (inlet).
There are two filters on the front (front filter) and left side (side filter).
When replacing the filters, buy the optional filter NP02FT in advance.
