Turn on the projector and switch to the image

Light Source Mode setting.
Select one of the
following options:
Auto: Sets
brightness automatically (available when you install the projector
upside down)
Normal:
Sets brightness to the maximum level (ideal for conference rooms,
auditoriums, and lecture halls)
Quiet: Sets
brightness to 70% and reduces fan noise (ideal for libraries,
theaters, museums, and art galleries)
Extended:
Sets brightness to 70% and extends the life expectancy of the light
source (ideal for darker environments with ambient light, such as
museums and art galleries, where a reduced maintenance cycle is
desired)
Custom:
Allows you to select a custom brightness level between 70 to
100%
If you selected
Custom, select Brightness Level from the Brightness Settings
screen and use the left and right arrow buttons to select the
brightness.
If you selected
Custom and want to maintain
consistent brightness, turn on the Constant Brightness setting.
Note: If you
turn on Constant Brightness, you
cannot change the Light Source
Mode and Brightness Level
settings. If you turn off Constant
Brightness, the Brightness
Level setting changes according to the status of the light
source.
Press Menu
or Esc to return to the previous
screen.
Note: If you
use the projector continuously for more than 24 hours, or regularly
turn it off by shutting off the power outlet, schedule periodic
Light Source Calibration events
from the Extended menu. Otherwise, the Constant Brightness setting may not work
properly.
