Switch the fan mode to suit installation at low or high altitudes (above 2,300 m [7,545.8 ft.]).

Setting for altitudes of 2,300 m (7,545.8 ft.) or higher.

You can ensure adequate cooling by switching the fan mode to suit upward- or downward-
facing installations.

Off

Does not alter the fan mode.

Upward

Setting for use when the projector faces upward.

Downward

Setting for downward projection.

To ensure that optical parts last as long as possible, you can increase the fan speed.

Normal

Sets the fan to a slower speed. Use when quiet operation is required.

High speed

Increases the fan speed, for a relatively longer useful life of optical parts. 
Although the fan will be louder, use this setting if the useful life of optical 
parts is most important.

• [Registration] and [Advanced registration] settings are retained even if you change 

the panel drive mode.

• 5-point adjustment enables basic correction of color misalignment across the 

screen, by moving adjustment points in the center and each corner. To correct 
registration only in certain areas, try manual adjustment.

• Any values you set in 5-point adjustment are retained if you subsequently perform 

manual adjustment. For more precise correction after 5-point adjustment, perform 
manual adjustment.

• Any manual adjustment values you set before switching to 5-point adjustment are 

cleared.

Incorrect settings may shorten the useful life of the lamp or other parts.

• Be sure to perform this setting to use vertical projection.
• Projecting vertically without using this setting will shorten the useful life of the lamp 

and other parts.

• Even if you complete this setting, vertical projection will result in a shorter useful life 

of the lamp and other parts than horizontal projection.
