[Differential (Normal) + copy + WARM adjustment]
Adjustment of [COOL], [WARM] by data shift from [NORMAL] adjust.
And only [WARM] is readjusted.
Execute adjustment for color temp. [NORMAL], and set data for color temp. [COOL], [WARM] by data shift WB
of HD (or PAL) copies the adjustment data from an adjusted format side.

of HD (or PAL) copies the adjustment data from an adjusted format side.
Note:
The adjustment does color temp. [NORMAL] first.
A adjustment value difference from [NORMAL] is written to EEPROM as for [COOL] and [WARM] by
operating a [OK] key.
As for WB of HD (or RF), the adjustment data from an adjusted format side is copied simultaneously.
Text color of the adjusted value changes into red -> black at the same time too. And only [WARM] is
readjusted.
