[NOTES]
1. Set R6040 - 6046(TX-NR525/HT-RC550 are R6040-6044) 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(TX-NR525/HT-RC550 are P6080-6084) terminals.
[PROCEDURES]
a. Set the voltages at P6080 - 6082 to 2.5mV by adjusting R6040 - 6042, under the condition of
no input and no load, immediately after POWER ON.
b. Set the voltages at P6083-6086(TX-NR525/HT-RC550 are P6083-6084) to 1.5mV by adjusting
R6043 - 6046(TX-NR525/HT-RC550 are R6043 - 6044), 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.
