C317 C320 詳 “PRINTED CIRCUIT BOARDS” 参照 。 Safety measures Some internal parts in this product contain high voltages and are dangerous. Be sure to take safety measures

31、during servicing, such as wearing insulating gloves. Note that the capacitors indicated below are dangerous even after the power is turned off because an electric charge remains and a high voltage continues to exist there. Before starting any repair work, connect a discharging resistor (5 k-ohms/10

32、W) to the terminals of each capacitor indicated below to discharge electricity. The time required for discharging is about 30 seconds per each. C317 to C320 on MAIN (3) P.C.B.
