1. Precautions 1. Precautions 1-1. Safety Precautions Follow these safety, servicing and ESD precautions to prevent damage and to protect against potential hazards such as electrical shock. 1-1-1. Warnings For continued safety, do not attempt to modify the circuit board. Disconnect the AC power and DC power jack before servicing.
Page 49
1. Precautions 1-1-4. Product Safety Notices Some electrical and mechanical parts have special safetyrelated characteristics which are often not evident from visual inspection. The protection they give may not be obtained by replacing them with components rated for higher voltage, wattage, etc.
Page 50
1. Precautions 1-2. Servicing Precautions An electrolytic capacitor installed with the wrong polarity might explode. WARNING Before servicing units covered by this service manual, read and follow the Safety Precautions section of this manual. CAUTION If unforeseen circumstances create conflict between the following servicing precautions and any of the safety precautions, always follow the safety precautions.
Page 51
1. Precautions 1-3. Static Electricity Precautions Some semiconductor (solid state) devices can be easily damaged by static electricity. Such components are commonly called Electrostatically Sensitive Devices (ESD). Examples of typical ESD are integrated circuits and some field-effect transistors. The following techniques will reduce the incidence of component damage caused by static electricity. Immediately before handling any semiconductor components or assemblies, drain the electrostatic charge from your body by touching a known earth ground.
