Cleaning and replacing the air filter
The air filter has two kinds of filters inside. Please check and clean the air filter periodically.
When the indicators or a message prompts you to clean the air filter, comply with it as soon
as possible. If the filters are damaged or heavily soiled, replace them with the new ones. To
prepare the new filters, make contact with your dealer and tell the following type number.
Type number : UX35971 (Filter unit)
When you replace the lamp, please replace the air filter. An air filter of specified type will
come together with a replacement lamp for this projector.
1.
Turn the projector off, and unplug the power cord.
Allow the projector to sufficiently cool down.
2.
Use a vacuum cleaner on and around the filter cover.
3.
Pick and pull up the filter cover knobs to take it off.
4.
Use a vacuum cleaner for the filter vent of the projector.
5.
Take the fine meshed filter out while holding the filter
cover. It is recommended to leave the coarse meshed
filter in the filter cover as it is.
6.
Use a vacuum cleaner on both sides of the fine
meshed filter while holding it so it will not be sucked
in. Use a vacuum cleaner for the inside of the filter
cover to clean up the coarse meshed filter. If the filters
are damaged or heavily soiled, replace them with new ones.
7.
Put the fine meshed filter on the coarse meshed one, turning
its stitched side up.
8.
Put the filter unit back into the projector.
9.
Turn the projector on and reset the filter time using the FILTER
TIME item in the EASY MENU.
(1) Press the MENU button to display a menu.
(2) Point at the FILTER TIME using the ▲/▼ cursor buttons,
then press the ► cursor (or the ENTER / the RESET) button.
A dialog will appear.
(3) Press the ► cursor button to select the "OK" on the dialog.
It performs resetting the filter time.
WARNING ►Before taking care of the air filter, make sure the power cable
is not plugged in, then allow the projector to cool sufficiently.
►Use only the air filter of the specified type. Do not use the projector without the
air filter or the filter cover. It could result in a fire or malfunction to the projector.
►Clean the air filter periodically. If the air filter becomes clogged by dust or the like,
internal temperatures rise and could cause a fire, a burn or malfunction to the projector.
NOTE • Please reset the filter time only when you have cleaned or replaced
the air filter, for a suitable indication about the air filter.
• The projector may display the message such as the "CHECK THE AIR FLOW"
or turn off the projector, to prevent the internal heat level rising.
