should be convenient for using exploitation tool to adjust. The setting will not be memory and will
be "OFF" when power on again;
p) Backlight: adjust the backlight brightness, adjust the data and test the voltage of X804 pin2
(PWM), let the voltage to be the corresponding PWM voltage which the brightness is maximum.
It will be preset and doesn't need adjust.
q) SSC Adjust, adjust the frequency spectrum expand, it will be preset and doesn't need adjust.
r) AUDIO Curve, adjust the sound curve, it will be preset and doesn't need adjust.
s) Picture Mode, set the picture values of each channel. Normally, they are preset and needn't
adjust.
t) There is data in EEPROM after software upgrade, please perform Reset All before the first
adjustment.
