    Register 24 (OP4): This register has CC line number - (Low nibble to 60Hz and high nibble to 50Hz) The Bits 0,1,2,3 are used to select the line where Closed Caption information will be extracted when in 60Hz, and the bits 4, 5, 6, 7 are used to select the line where Closed Caption information will be extracted when in 50Hz Note: This information is used by microcontroller.
  • Page 25 White balance Note: The cut point doesn’t need adjustment, because it’s automatically made by the IC501. The white adjustment is already pre-adjusted and incised in the IC501 and, thus, its adjustment is not necessary. Otherwise, if it is necessary to change the temperature of the white pattern, proceed in the following way: a) Enter in the service mode.
