MAKE LEAKAGE-CURRENT OR RESISTANCE MEASUREMENTS TO DETERMINE THAT EXPOSED PARTS ARE ACCEPTABLY INSULATED FROM THE SUPPLY CIRCUIT BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER. RadioFans.CN 收音机爱 好者资料库 ADJUSTMENT PROCEDURE SKW-980 : POWERED SUBWOOFER (EuP AMP.) / ADJUSTMENT OF IDLING CURRENT HTP-980 Test point DC voltmeter 100 ohm (1/4W) P531 Test point P631 MAIN PC board assy BAAF-0491 (EuP Amp.) Test point P531 Trimming resistor R544 Short When 1. Exchange transistors (Q505 - Q519). 2. Exchange MAIN PC board assy (BAAF-0491). Procedure No speaker load and No input signal. 1. Short test point P631 for amplifier is under active mode. 2. Adjust the trimming resistor R544 so that the reading of multimeter becomes 52 ohm to 53 ohm. 3. Connect the DC voltmeter to test point P531. 4. Connect the power cord into the AC outlet. 5. Press POWER button to turn on the unit. (MPP only) 6. Confirm the voltage of above point after 6 minutes to 8 minutes. (Heat running) 7. When less than 3.20 mV : Readjust the trimming resistor above so that the voltage becomes 4.5 mV to 5.0 mV. When 3.30 mV to 5.20 mV : Not necessary to adjust. When 5.21 mV to 10.0 mV : Readjust the trimming resistor above so that the voltage becomes 5.0 mV to 5.5 mV. When 10.1 mV to 20.0 mV : Readjust the trimming resistor above so that the voltage becomes 5.6 mV to 6.0 mV. 8. Disconnect the power cord from the AC outlet. 9. Disconnect the DC voltmeter.
