When replacing a component identified with, use only the replacement parts designated, or parts with the same ratings or resistance, wattage, or voltage that are designated in theparts list in this manual. Leakage-current or resistance measurements must

9、 be made to determine that exposed parts are acceptablyinsulated from the supply circuit before retuming the product to the customer.Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are calledElectrostatically Sensitive (ES) Devices. Exam

10、ples of typical ES devices are integrated circuits and some field effect transistors andsemiconductor chip components.The following techniques should be used to help reduce the incidence of component damage caused by static electricity.1. Immediately before handling any semiconductor component or se

11、miconductor-equipped assembly, drain off any electrostatic charge onyour body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device,which should be removed for potential shock reasons prior to applying power to the unit under test.2.

12、 After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, toprevent electrostatic charge build-up 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

13、 solder removal device. Some solder removal devices not classified as anti-static can generate electrical chargessufficient to damage ES devices.5. Do not use freon-propelled chemicals. These can generate electrical change sufficient to damage ES devices.6. Do not remove a replacement ES device from

14、 its protective package until immediately before you are ready to install it. (Most replacementES 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 o

15、f a replacement ES device, touch the protective material to thechassis or circuit assembly into which the device will be installed.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 device

16、s. (Otherwise harmless motion such as the brushing togetheror your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES devices.CAUTION :AVR435/635 AVR435/635 harman/kardon www.freeservicemanuals.infoIts Freewww.freeservicemanual
