3、omponents identified with the IEC symbolin the parts list are special significance to safety. 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.

4、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 calle

5、dElectrostatically 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 be

6、fore 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 pr

7、ior 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

8、 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 device

9、s.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 re

10、moving 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

11、 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 165/230V Service ManualPage

30、ception.HDMI Monitor Out connector: If your tV has an hdMI connector and you have hdMI or component video source devices, use an hdMI cable (not included) to connect it to the AVrs hdMI Monitor out connector. Notes on using the HDMI Monitor Out connector: when connecting a dVI-equipped display to th

31、e hdMI Monitor out connector, use an hdMI-to-dVI adapter and make a separate audio connection.Make sure the hdMI-equipped display is hdcp-compliant. If it isnt, do not connect it via hdMI; use an analog video connection instead and make a separate audio connection.HDMI Input connectors: the hdMI (hi

32、gh-definition Multimedia Interface) feature is a connection for transmitting digital audio and video signals between devices. If your source devices have hdMI connectors, using them will provide the best possible video and audio performance quality. Since the hdMI cable carries both digital video an

33、d digital audio signals, you do not have to make any additional audio connections for devices you connect via hdMI connections. See connect Your Source devices, on page 13, for more information.Composite Video Monitor Out connector: If your tV or video display does not have an hdMI connector, or if

34、your tV does have an hdMI connector but you are connecting some source devices with only composite video connectors, use a composite video cable (not included) to connect the AVrs composite Video Monitor out connector to your tVs composite video input connector. DVD Component Video Input connector:

35、If your blu-ray disc or dVd player does not have an hdMI connector but does have a component video connector, using the component video connector will provide superior video performance. You will also need to make an audio connection from the player to the AVr.Digital Audio Input connectors: If your

36、 non-hdMI source devices have digital outputs, connect them to the AVrs digital audio connectors. note: Make only one type of digital connection (hdMI, optical or coaxial) from each device. See connect Your Source devices, on page 13, for more information.Video 2 Out connector: connect an analog vid

37、eo recorders video input connector to the AVrs Video 2 out connector. You can record any composite video input signal. note: to record the audio and video from the source device, connect the AVrs Video 2 out Analog output connectors to the analog video recorders audio inputs.Composite Video Input co

38、nnectors: use composite video connectors for video source devices that dont have hdMI or component video connectors. You will also need to make an audio connection from the source device to the AVr. See connect Your Source devices, on page 13, for more information.IR Remote In/Out connectors: when t

39、he Ir Sensor on the front panel is blocked (such as when the AVr is installed inside a cabinet), connect an optional Ir receiver to the Ir remote In connector. the Ir remote out connector may be connected to the Ir input of a compatible product to enable remote control through the AVr.
