Exit: Exit from Factory mode and back to NO OSD Status.

  Panel: The current-setting panel is highlighted.
  Auto Color: Automatically calibrate chip ADC parameters by using internal DAC.
  Burn In: Enable or disable the Burn-in mode by choosing ON or OFF.
  Reset Time: Reset the “Turn-on time” of the panel to 0H0M.
  Color Temp: The R, G, B of Blue Preset (9300K), Red Preset (5700K) and Normal
Preset (6500K) are generated

from scaling chip’s back-end white-balance program.

Time: Turn-on time of the panel.
DEBUG: Debug tool of scale IC U105.
