Using a. 10oM, 10 W resistor, shortcircuit both ends of power supply capacitors C001, C002. C705 and C706 in order to discharge the voltage. (2) Before turning on the power switch of the unit, A. Connect the voltage controller to the primary side. B. Connect the AC ampere meter to the primary side or conned the DC voltage meter to the B circuit of the secondary side. C. Turn the VR of ICQ (VR451, VR452. VR501 and VH502) to minimum (counterclockwise). D. Alter setting the output to zero of the voltage controller, turn on the power switch of the unit. And increase the output of voltage controller gradually. Then, check carefully whether the current value of primary side become more than following value or whether the DC voltage of secondary side is increasing slowly. E. II the value of current is increasing unusually or the DC voltage is not increasing, lower the output level of voltage controller Immediately. The current value of the primary side at no signal. (Confirm the power supply voltage ot each area and provided voltage of the unit.)

Sound stops during a performance. The function of this circuitry is to prevent circuitry damage if, for example, the positive and negative speaker connection wires are shorted, or if speaker systems with an impedance less than the indicated rated Impedance of the amplifier are used. It this occurs, follow the procedure outlined below: 1. Turn off the power. 2. Determine the cause of the problem and correct it. 3. Turn on the power once again. Note: When the protection circuitry functions, the unit will not operate unless the power is first turned off and then on again. I ACCESSORY AC power supply cords For (E), (EG) areas.
