Fan Mode
Fan Mode is used to set the speed of the internal cooling fan.
Mode – Normally select Auto, which enables the projector to automatically detect fan
requirements. Select High Altitude when using the projector at altitudes ap-
proximately 5000 feet/1500 meters or higher. The built-in fans run at a high
speed.
Orientation –
Select either Horizontal or Vertical according to the installation angle of the
projector. Select Horizontal for angles of range from 45° to 315° and from
135° to 225° indicated in gray. Select Vertical for the other angle ranges.
CAUTION
When the projector is mounted on the ceiling at the installation angles
from 45° to 135°, make sure that no one is under the projector. Glass
fragments could fall if the lamp has been burned out.
Note:
‧
Set Fan Mode to High Altitude when using the projector at altitudes approxi-
mately 5000 feet/1500 meters or higher.
‧
Using the projector at altitudes approximately 5000 feet/1500 meters or higher
without setting to High Altitude can cause the projector to overheat and the protec-
tor could shut down. If this happens, wait a couple minutes and turn on the
projector.
‧
Using the projector at altitudes less than approximately 5000 feet/1500 meters
and setting to High Altitude can cause the lamp to overcool, causing the image to
flicker.
‧
Using the projector at altitudes approximately 5000 feet/1500 meters or higher
can shorten the life of optical components such as the lamp.

Your setting will not be affected even when Reset is done from the menu.
