[NOTES]
1. Set R5440-5442 and 6043-6046 to minimum position before POWER ON.
2. Equip series 1/4W 100-ohm resisters near the terminal respectively in the each poles of the jig
used for P6080 - 6086 terminals.
[PROCEDURES]
a. Set the voltages at P6080 - 6082 to
6.0 mV
by adjusting R5440 - 5442, under the condition of
no input and no load, immediately after POWER ON.
b. Set the voltages at P6083 - 6086 to
4.0 mV
by adjusting R6043 - 6046, under the condition of
no input and no load, immediately after POWER ON.
c. Re-adjust by following procedure after 5 minutes of heat running.
