  • Page 3: Safety Precautions

    1 Safety Precautions 1.1. General Guidelines 1. When conducting repairs and servicing, do not attempt to modify the equipment, its parts or its materials. 2. When wiring units (with cables, flexible cables or lead wires) are supplied as repair parts and only one wire or some of the wires have been broken or disconnected, do not attempt to repair or re-wire the units.
  • Page 4: Warning

    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 Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors and semiconductor [chip] components.
