8. Maintenance
This section describes the simple maintenance procedures you should follow to clean the filter and replace the lamp.
ᕡ Cleaning 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 filters are dirty or clogged, your projector may overheat.
CAUTION
• Turn off the projector, turn off the main power switch and unplug the projector before cleaning the filters.
• Only clean the outside of the filter cover with a vacuum cleaner.
1. Vacuum the filter from the outside.
2. Reset the filter usage time.
To reset the filter usage time, from the menu, select [Setup]
→ [Page 5] → [Filter Usage] → [Clear Filter Usage Meter]
and then press “Clear”.
See also page 98 for resetting the filter usage time.
ᕢ Cleaning the Cabinet
CAUTION
Turn off the projector, turn off the main power switch and unplug the projector before cleaning the cabinet.
Clean the cabinet periodically with a damp cloth. If heavily soiled, use a mild detergent. Never use strong
detergents or solvents such as alcohol or thinner.
