Cleaning or Replacing the Filters

5.After you install a new lamp, select [Advanced Menu] → [Projector Options]→[Setup]→[Page 4]→[Clear Lamp Hour Meter] to reset the lamp usage hours.

NOTE: When the lamp exceeds 1100 hours (up to 2100 hours in Eco 2 mode and up to 1600 hours in Eco 1 mode) of service, the projector cannot turn on and the menu is not displayed. If this happens, press the Help button on the remote control for a mini- mum of 10 seconds while in standby mode. When the lamp time clock is reset to zero, the STATUS indicator goes out.

To replace the air-filter:

1.Remove the filter cover by pushing up on the catch of the cover until you feel it detach.

The air-filter sponge keeps the inside of the VT45 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 correctly.

To clean the air-filter:

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 “Menu” - “Fil- ter Clean Message” option on the Setup menu. See page E- 33.

•After cleaning the filters and resetting the filter usage time back to zero, the message will not be displayed.

See page E-35 for resetting the filter usage time.

Vacuum the filter-through the filter cover.

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 membrane. Before replacing the filter cover, remove dust and dirt from the projector cabinet. Keep out dust and during filter replacement.

NOTE: When you replace the lamp, it is also wise to replace the filters. The filters come in the same package with your replace- ment lamp.

NOTE: A mix-up between the two filter covers can cause a dam- age to the projector.

The front and the side filter covers appear to be the same shape, but they are not interchangeable with each other.
