TX-DS494/HT-R490 ADJUSTMENT PROCEDURES
IDLING CURRENT ADJUSTMENT
1. Before Idling adjustment, turn the trimming resistors R573, R574, R673, R674 and R1532 to counter clockwise. 2. Connect the DC voltmeter to sockets P511,P512, P611, P612 and P1511. 3. After turn POWER to ON, adjust the trimming resistors R573, R574, R673, R674 and R1532 so that the reading of voltmeter becomes 2.4 to 2.6 mV. 4. After adjustment, attach the top cover. 5. Confirm the voltage of above points after five minutes. 6. When 3.1 mV to 6.4 mV : Readjust the trimming resistors above so that the voltage becomes 6.5 to 6.7 mV. When 6.5 mV to 7.5 mV : It is not necessary to adjust. When 7.6 mV to 13 mV : Readjust the trimming resistors above so that the voltage becomes 7.5 to 7.7 mV.
