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 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. Examples 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 semiconductor-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. 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 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 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 of 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 devices. (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 : Harman KardonAVR 170 / 230V Service ManualPage 2 of 114RadioFans.CN 收音机爱 好者资料库Audio/video receiverAVR 1700, AVR 170, AVR 170/230COwners ManualHarman KardonAVR 170 / 230V Service ManualPage 3 of 114AVR2Table of ContentsIntroductIon 3SupplIed AcceSSorIeS 3ImportAnt SAfety InformAtIon 3plAce the AVr 3front-pAnel controlS 4reAr-pAnel connectorS 6SyStem remote control functIonS 8IntroductIon to home theAter 10typIcAl home theAter SyStem 10multIchAnnel AudIo 10Surround modeS 10plAce your SpeAkerS 10plAcIng the left, center And rIght SpeAkerS 10plAcIng the Surround SpeAkerS 10plAcIng the Subwoofer 10typeS of home theAter SyStem connectIonS 11SpeAker connectIonS 11Subwoofer connectIonS 11Source deVIce connectIonS 11VIdeo connectIonS 12rAdIo connectIonS 12uSb/ipod port 12mAkIng connectIonS 13connect your SpeAkerS 13connect your Subwoofer 13connect your tV or VIdeo dISplAy 13connect your AudIo And VIdeo Source deVIceS 13connect to your home network 15connect the rAdIo AntennAS 15connect Ir equIpment 15connect the trIgger output 15connect to Ac power 16Set up the remote control 16InStAll the bAtterIeS In the remote control 16progrAm the remote to control your Source deVIceS And tV 16Set up the AVr 17turn on the AVr 17uSIng the on-Screen menu SyStem 17confIgure the AVr for your SpeAkerS 17ASSIgn the AVr Input connectorS 18Set up the network 18AddItIonAl Source Setup menu ItemS 19operAtIng your AVr 19controllIng the Volume 19mutIng the Sound 19lIStenIng through heAdphoneS 19SelectIng A Source 19VIdeo troubleShootIng tIpS 19lIStenIng to fm And Am rAdIo 20lIStenIng to Internet rAdIo (vtuner) 20lIStenIng to An ipod/iphone/ipad deVIce 20lIStenIng to medIA on A uSb deVIce 20lIStenIng to medIA VIA your home network 21lIStenIng to medIA VIA AIrplAy 22SelectIng A Surround mode 22AdVAnced functIonS 23AudIo proceSSIng And Surround Sound 23mAnuAl SpeAker Setup 24SyStem Setup 26AdVAnced remote control progrAmmIng 26recordIng 27Sleep tImer 27reSettIng the remote 27proceSSor reSet 27memory 27troubleShootIng 28SpecIfIcAtIonS 29AppendIx 30Harman KardonAVR 170 / 230V Service ManualPage 4 of 114AVR3EnglishIntroduction, Supplied Accessories, Important Safety Information and Place the AVRIntroductionThank you for choosing this Harman Kardon product! for more than fifty years, the harman kardon mission has been to share a passion for music and entertainment, using leading-edge technology to achieve premium performance.
