11. The value of WB_GAM_R(B)01 is determined by the following conditions.
a).For 40 inch models
·
WB_GAM_R01 = WB_GAM_R02 - (WB_GAM_R03 - WB_GAM_R02)
·
WB_GAM_B01 = WB_GAM_B02 + {(WB_GAM_B03 -WB_GAM_B02)}/2
a).For 46 inch models
·
WB_GAM_R01 = WB_GAM_R02 - (WB_GAM_R03 - WB_GAM_R02) x 2
·
WB_GAM_B01 = WB_GAM_B02 - (WB_GAM_B03 -WB_GAM_B02)
12. The value of WB_GAM_R(B)06, WB_GAM_R(B)07 is determined by the following conditions.
a).For 40 inch models
·
WB_GAM_R06 = WB_GAM_R05 + {(WB_GAM_R04 - WB_GAM_R05)} / 2
·
WB_GAM_B06 = WB_GAM_B05 - {(WB_GAM_B04 - WB_GAM_B05)} / 2
·
WB_GAM_R07 = WB_GAM_R04
·
WB_GAM_B07 = WB_GAM_B05 - (WB_GAM_B04 - WB_GAM_B05)
a).For 46 inch models
·
WB_GAM_R06 = WB_GAM_R05 - {(WB_GAM_R04 - WB_GAM_R05)} / 2
·
WB_GAM_B06 = WB_GAM_B05
·
WB_GAM_R07 = WB_GAM_R05 - (WB_GAM_B04 - WB_GAM_B05)
·
WB_GAM_B07 = WB_GAM_B05 - (WB_GAM_B04 - WB_GAM_B05)
13. Send ECS command: WB_SAVE.
