1.10. Ghost feedback calibration
This ghost feedback (GCFB) function operates to control the ghost
to be the best position constantly by detecting the aging fluctuation
of GCFB pulse generated from LCD panels. Projector reads out the
pulse status at the production and memorizes it as initial value.

should be done to get its initial value.

CALIBRATION].
2. Press [ENTER] button to start the calibration.

screen.
4. Press [MENU] button to exit the adjustment mode.
