Preparation(1) Prepare a DC voltmeter.(2) Place the unit under normal usage conditions, away from highly ventilated areas such as next to anair conditioning machine or electric fan.The set requires an ambient temperature of 15℃ to 30℃ and standard humidity.(3) Settings of This Unit• POWER (Power source switch) STANDBY• SPEAKER (Speaker terminal) No load(Do not connect equipment such as speakers or dummy resistors.)2. Adjustment Procedure(1) Remove the top cover and turn VR510( (ALL Channel) of the MAIN PCB counterclockwise(c) as faras possible.(2) Connect the DC Voltmeter to the test points.FRONT-Lch : CN510 : VR510FRONT-Rch : CN550 : VR550CENTER ch : CN530 : VR530SURROUND-Lch : CN520 : VR520SURROUND-Rch : CN540 : VR540SURROUND-BACK Lch : CN560 : VR560SURROUND-BACK Rch : CN570 : VR570(3) Connect the power cord to an outlet. Next, press the power button to turn on the power.(4) Set this unit as follows.MASTER VOLUME : "---" (c min.) : turn counterclockwise to the lowest position.SPEAKER (Speaker terminal) : No load(Do not connect equipment such as speakers or dummy resistors.)MODE : MCH STEREOFUNCTION : DVD(5) Turn VR510 clockwise (x) and adjust the voltage of the test point to "2.0mV ± 0.5mV DC" within 2minutes.(6) Check whether the voltage is within the range "2.0mV +2mV/-1mV DC" 10 minutes after adjust-ment.(7) Adjust the variable resistance of each channel using the same method.138Caution inservicing Electrical Mechanical Repair Information Updating
