To change the FD coefficient, shift 6-digit FD switches. When the switch shifts to ON, it means “1”,
otherwise means “0”.
Convert the 6-digit binary number into decimal number. Multiple the decimal number by 2, the result
is FD coefficient, as shown in Figure 4-9.
The Max. value is “111111” which is 63 * 2 FD.
