Cleaning Or Replacing The Filters - NEC GT950 User Manual

Cleaning or Replacing the Filters

The air-filter sponge keeps the inside of the GT950 Projector free from
dust or dirt 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 power and unplug the projector before replacing the filter.
• Only clean the outside of the filter cover with a vacuum cleaner.
• Do not attempt to operate the projector without a filter cover.
• Your projector will not operate unless the filter cover is installed cor-
rectly.
To clean the air-filter:
Vacuum the filter-through the filter cover.
When "Clean Filter" option is turned on, the "Please clean the filters"
message will be displayed each time the projector is turned on after it
has been used in excess of 100 hours. Should this message appear,
clean the filters.
• The message can be turned on or off using the [Projector Options]→
[Menu]→[Page 2]→[Message · Clean Filter]. See page E-43.
• After cleaning the filters and resetting the filter usage time back to
zero, the message will not be displayed.
See page E-45 for resetting the filter usage time.
To replace the air-filter:
1. Remove the filter cover by pushing up on the catch of the cover
until you feel it detach.
2. Reinstall the new filter cover.
NOTE: Do not detach the sponge from the filter cover. Do not wash the filter
cover with soap and water. Soap and water will damage the the filter mem-
brane. Before replacing the filter cover, remove dust and dirt from the pro-
jector cabinet. Keep out dust and during filter replacement.
