1 Safety Precautions 1.1. General Guidelines 1.3. Leakage Current Hot Check (See Figure. 1) 1. IMPORTANT SAFETY NOTICE There are special components used in this equipment 1. Plug the AC cord directly into the AC outlet. Do not use which are important for safety. These parts are marked by an isolation transformer for this check.
1.4. How to Discharge the E.Capacitor on E.Capacitor P.C.B. • This unit equipped with two pieces of capacitors as E.Capacitor. “Either one of the E.Capacitor discharging operation” makes discharging for others as well. CAUTION: • Be sure to discharge the E.Capacitors on E.Capacitor P.C.B. before disassembling. •...
2 Warning 2.1. Prevention of Electrostatic Discharge (ESD) to Electrostatically Sensitive (ES) Devices Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Elec- trostatically Sensitive (ES) Devices. The following techniques should be used to help reduce the incidence of component damage caused by electrostatic discharge (ESD).
