                               When servicing, observe the original lead dress. If a short circuit is found, replace all parts
                               which have been overheated or damaged by the short circuit.
                               After servicing, see to it that all the protective devices such as insulation barriers, insulation
                               papers shields are properly installed.
                               After servicing, make the following leakage current checks to prevent the customer from
                               being exposed to shock hazards.
                               1) Leakage Current Cold Check
                               2) Leakage Current Hot Check
                               3) Prevention of Electrostatic Discharge (ESD) to Electrostatically Sensitive

                               the incidence of component damage caused by static by static electricity.
                               1. Before handling any semiconductor component or semiconductor equipped assembly,
                                  immediately drain off any electrostatic charge on your body by touching a known earth
                                  ground. Alternatively, obtain and wear a commercially available discharging wrist strap
                                  device, which should be removed to prevent potential shock reasons prior to applying
                                  power to the unit under test.
                               2. After removing an electrical assembly equipped with ES devices, place the assembly
                                  on a conductive surface such as aluminum foil, to prevent electrostatic charge buildup
                                  or exposure of the assembly.
                               3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.
                               4. Use only an anti-static type solder removal device. Some solder removal devices not
                                  classified as "anti-static" can generate electrical charges sufficient to damage ES
                                  devices.
                               5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient
                                  to damage ES devices.
                               6. Do not remove a replacement ES device from its protective package until immediately
                                  before you are ready to install it.
                                    (Most replacement ES devices are packaged with leads electrically shorted together by
                                    conductive foam, aluminum foil or comparable conductive material).
                               7. Immediately before removing the protective material from the leads of a replacement
                                  ES device, touch the protective material to the chassis or circuit assembly into which
                                  the device will be installed.
                               CAUTION: Be sure no power is applied to the chassis or circuit, and observe all other
                               safety precautions.
                               8. Minimize bodily motions when handling unpackaged replacement ES devices.
                               (Otherwise harmless motion such as the brushing together of your clothes fabric or the
                               lifting of your foot from a carpeted floor can generate static electricity sufficient to damage
                               an ES device.)
