NEVER touch the HOT part or the HOT and COLD parts at the same time, or you may get an electric shock.4.2. S / V / L -P.C.Board 2. NEVER short-circuit the HOT and COLD circuits, or the fuse may blow and the parts may break.4. MAKE SURE to unplug the power cord from the power outlet before removing the chassis.5. When ordering parts, please check the part number of the "Replacement Parts List".3. NEVER connect an instrument such oscilloscope to the HOT and COLD circuit simultaneously, or the fuse may blow.Connect the ground of instruments to the ground of the circuit being measured.CONTENTSModel No. PT-AE8000UPT-AT6000EPT-AE8000EA / AE8000EH / AE8000EZSECTION 4< Schematic Diagram > Components identified by the intemational symbol have special characteristics important for safety.When replacing any of these components, use only the manufacturer's specified ones.The power circuit board contains a circuit area using a separate power supply to isolate the ground connection.The circuit is defined by HOT and COLD indications in the schematic diagram.
