  • Page 4 1 Use of Active Subwoofer 1.1 Checking Player when Active Subwoofer is not used This unit uses the active subwoofer to supply the power of the component, and the active subwoofer should be connected to the component to check operational conditions of the component. If the active subwoofer is not available due to repair of the unit, use the following equipment.
  • Page 5 2 Safety Precautions 2.1 GENERAL GUIDELINES When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly installed.
  • Page 6 3 Prevention of Electro Static Discharge (ESD) to Electrostatically Sensitive (ES) Devices Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field- effect transistorsand semiconductor "chip"...
  • Page 7 4 Before Repair and Adjustment (Using Active Subwoofer) Disconnect AC power, discharge Power Supply Capacitors C546~C549 through a 10 Ω, 10 W resistor to ground. DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy solid state devices. After repairs are completed, restore power gradually using a variac, to avoid overcurrent.
  • Page 8 5 Protection Circuitry The protection circuitry may have operated if either of the following conditions are noticed: No sound is heard when the power is turned on. 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.
  • Page 9 6 Precaution of Laser Diode CAUTION: This unit utilizes a laser. Invisible laser radiation is emitted from the optical pickup lens when the unit is turned on. Wavelength: 662nm(DVD)/785nm(VCD/CD). Maximum output radiation power from pickup: 100µW/VDE Do not look directly into the pick up lens. Do not use optical instruments to look at the pick up lens.
  • Page 10 7 About Lead Free Solder (PbF) Distinction of PbF PCB: PCBs (manufactured) using lead free solder will have a Pbf stamp on the PCB. Caution: Pb free solder has a higher melting point than standard solder; Typically the melting point is 50 - 70°F (30 - 40°C) higher.
