High altitude
Switch the fan mode to suit installation at low or high altitudes (above 2,300 m [7,545.8']).
Option
Function
Off
Setting for altitudes lower than 2,300 m (7,545.8').
On
Setting for altitudes of 2,300 m (7,545.8') or higher.
Operating mode
Switch the method of controlling the light source and fan.
Option
Function
Normal
Normal drive mode. Brightness will decrease with time.
Fixed brightness
Maintains nearly the same brightness set at installation. Laser diode
wear is detected by a sensor, and current is increased to compensate
for wear.
Long duration 1
Enables a relatively longer useful life of optical parts by reducing the
brightness level of the light source mode and regulating the fan drive.
Long duration 2
Enables an even longer useful life of optical parts by further reducing
the brightness level of the light source mode and more aggressively
regulating the fan drive.
Lens shift mode
Switch the available lens shift range as needed.
Option
Function
Normal
Provides a normal lens shift range.
Expanded
Provides an expanded lens shift range.
Incorrect settings may shorten the useful life of the projector components.
When using the projector continuously for 24 hours or more, or when turning the
projector off by unplugging it, execute light source calibration using one of the settings
below. If calibration is not executed, the projector will be unable to maintain fixed
brightness.
• Periodically specify [OK] in [Light source calibration] in [Calibration] (
• Specify CALIBRATION in [Schedule] (
).
• Selecting [Expanded] may lower image quality and keystone correction precision,
depending on the extent of lens shift.
• Selecting [Normal] when the lens is in the expanded range (outside the normal
position) will execute lens shift reset (
).
