1. Set the voltages at "P6080/6081/6082" to 2.5mV by adjusting
"R6040/6041/6042", under the condition of no input and
U0010
no load, immediately after POWER ON.
2. Set the voltages at "P6083/6084/6085/6086" to 1.5mV by
adjusting R6043/6044/6045/6046, under the condition of
no input and no load, immediately after POWER ON.
3. Re-adjust by following procedure after 4-6 minutes of
heat running.
