Cleaning or Replacing the Filters The air-filter sponge keeps dust and dirt from getting inside the projec\ tor 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 fi\ lters. • 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. To replace the filter (sponge): 1. Remove the filter cover by pushing down on the catch of the cover until \ you feel it detach. NOTE: The VT695/VT595/VT590/VT490 have two filters; the VT59 and VT49 ha\ ve one filter only. Catch 2. Gently peel off the filter (sponge) and replace it with the new one.
51 6. Maintenance 3. Reinstall the new filter cover.4. Clear the filter hours used. To reset the filter usage time, from the menu, select [Reset] → [Clear Filter Hours]. ( → page 49 for resetting the filter usage time.) NOTE: Do not wash the filter with soap and water. Soap and water will damage the filter membrane. Before replacing the f\ ilter, remove dust and dirt from the projector cabinet. Keep out dust and dirt \ during filter replacement. NOTE: When you replace the lamp, it is also wise to replace the filter. The filter comes in the same package with your replacem ent lamp. Cleaning the Cabinet and the Lens 1. Turn off the projector before cleaning. 2. Clean the cabinet periodically with a damp cloth. If heavily soiled, use\ a mild detergent.
