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.
WARNING
• Please do not use a spray containing flammable gas to remove dust attached to the filters, etc. Doing so may result in
fires.
NOTE: The message for lter cleaning will be displayed for one minute after the projector is turned on or o. When the message is displayed, clean the lters. The time to
clean the lters is set to [OFF] at time of shipment. (→ page 108)
To cancel the message, press any button on the projector cabinet or the remote control.
The two-layer filter on the projector improves cooling and dust-proof capabilities compared with the conventional models.
The outsides (the intake vent side) of the first and second layer filters remove dust.
To clean the filter, detach the filter unit and the filter cover.
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.
1. Press down on the buttons on the left and right and then pull the
filter cover towards you to open it.
The cover will open about 90 degrees before it stops.

detached if it is opened further. The filter cover will stop at a position

However, the filter cover may close if the projector vibrates.
