Light source
calibration automatically adjusts any difference between the white
balance and the brightness level of the light source. You should
perform light source calibration every 100 hours of projector
usage. You can also schedule automatic calibration or run the light
source calibration manually using the menus.
Note: To
perform a light source calibration, the projector must have been on
for at least 20 minutes and the projector
brightness must not be automatically dimmed due to high
temperatures.
