TX-SR600/E ADJUSTMENT AND CONFIRMATION PROCEDURES 1
Idling current adjustment Before Idling adjustment, turn the trimming resistors R6040 to R6045 to counter clockwise. Connect the DC voltmeter to sockets P6080 to P6085. After turn POWER to ON, adjust the trimming resistors R6040, R6041 and R6042 so that the reading of voltmeter becomes 2.5 mV. (Front and center channels) Adjust the trimming resistors R6043, R6044 and R6045 so that the reading of voltmeter becomes 1.5 mV. (Surround and surround back channels) After adjustment, attach the top cover. Confirm the voltage of points above after about five minutes. Front and center channels When less than 10.0 mV, readjust the resistors above so that the voltage becomes 10.0 mV. When 10.0 mV to 12.0 mV, you are not necessary to adjust. When more than 12.0 mV, readjust the resistors above so that the voltage becomes 12.0 mV. Surround and surround back channels When less than 7.0 mV, readjust the resistors above so that the voltage becomes 7.0 mV. When 7.0 mV to 9.0 mV, you are not necessary to adjust. When more than 9.0 mV, readjust the resistors above so that the voltage becomes 9.0 mV. Note: No load and No signal

Confirmation of protection circuit 1. Confirmation of operation of speaker relay Confirm that the speaker relays turn ON approximate. 5 seconds after the power switch is turned ON. Confirm that the speaker relays turn OFF immediately after the power switch is turned OFF. 2. Confirmation of DC detection circuit Press and hold down CD button, then press STANDBY/ON and DISPLAY buttons to set the unit to "Test-1" mode. After "Test-1" on the FL tube light on, press VIDEO 1 button to set the unit to "Test-1-00". Apply DC 1.5 to 3V to DVD INPUT terminal with no load. Confirm that the speaker relay turns OFF. Apply DC -1.5 to -3V to DVD INPUT terminal with no load. Confirm that the speaker relay turns OFF. Caution: Don't apply DC voltage more than 1 sec..
