This section describes the simple maintenance procedures you should follow to clean the filters, the lens, and the cabinet.

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 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. (

To cancel the message, press any button on the projector cabinet or the remote control.
CAUTION
• Before cleaning the filter, first turn off the power, make sure the cooling fan has completely stopped, then turn
off the main power switch. Make sure the unit has cooled down completely before cleaning the filter. Removing
the filter cover while the unit is running could result in burns or electric shock from contact with internal parts.
The unit uses a three layer metal-mesh filter installed behind the filter cover. It can be used repeatedly by periodical
cleaning.
There are four filters in total, located on the right and left sides. Clean all four at the same time.
