Maintenance
When the indicators or a message prompts you to clean the air filter, clean the
air filter as soon as possible. If the air filter becomes clogged by dust or the like,
internal temperatures rise and the power may be automatically turned off for
malfunction prevention.
1.
Disconnect all the connectors and adapters that were connected to the
projector’s ports. Then slowly turn the projector so that the lens-side is facing
up. Please be careful for a projector not to fall. While the projector is placed
lens-side up, hold the projector.
2.
Remove the filter cover and the air filter. Hold the knobs while pulling out it.
3.
Apply a vacuum cleaner to the vent of the projector for the air filter. And then
slowly turn the projector bottom up.
