    1. Safety Precaution (This “Safety Precaution” is applied only in U.S.A.) 1. Before servicing, unplug the power cord to prevent an electric shock. 2. When replacing parts, use only manufacturer’s recommended components for safety. 3. Check the condition of the power cord. Replace if wear or damage is evident.

  • Page 5: Before Repair And Adjustment

    2. Before Repair and Adjustment Disconnect AC power, discharge Power Supply Capacitors C703 - C706, C901, C904 and C1702 through a 10 , 5 W resistor to ground. DO NOT SHORT-CIRCUIT DIRECTLY (with a screw driver blade, for instance), as this may destroy solid state devices. After repairs are completed, restore power gradually using a variac, to avoid over current.
