6. Maintenance

This section describes the simple maintenance procedures you should follow to clean the filters and replace the lamp.

Cleaning or Replacing the Filters

The air-filter sponge keeps dust and dirt from getting inside the projector and should be cleaned after every 100 hours of operation (more often in dusty conditions). If the filter is dirty or clogged, your projector may overheat.

CAUTION

•Turn off the projector, turn off the main power switch and unplug the projector before replacing the filters.

•Only clean the outside of the filter cover with a vacuum cleaner.

•Do not attempt to operate the projector without the filter cover.

To clean the air-filter:

Vacuum the filter-through the filter cover.
