When replacing a component identified with, use only the replacement parts designated,

4、 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.

5、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 t

6、echniques 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

7、 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, to

8、prevent 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

9、 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 ele

10、ctrically 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

11、 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 c

26、E: If the PROTECT message ever appears on the AVRs front-panel message display, turn off the AVR and unplug it from the AC outlet. Check all speaker wires for a possible short-circuit (the “+” and “” conductors touching each other or both touching the same piece of metal). If a short-circuit is not

27、found, bring the unit to an authorized Harman Kardon service center for inspection and repair before using it again.Power button: Press this button to turn the receiver on or to place it in the Standby mode.Setup button: Press this button to access the AVRs main menu.Info button: Press this button t

28、o access the AVRs Source submenu, which contains the settings for the source currently playing.

When the on-screen display menu system (OSD) is in use, the current menu settings appear.IR sensor: This sensor receives infrared (IR) commands from the remote control. It is important

30、to ensure that the sensor is not blocked. AVR 3650/AVR 365 only: If covering the IR sensor is unavoidable (such as when the receiver is installed inside of a cabinet), connect an optional infrared receiver to the Remote IR In connector on the AVRs rear panel.Up/Down buttons: Use these buttons to nav

31、igate the AVRs menus.Volume knob: Turn this knob to raise or lower the volume.USB port: You can use this port to perform software upgrades that may be offered in the future. Do not connect a storage device, peripheral product or a PC here, unless you are instructed to do so as part of an upgrade pro

32、cedure.HDMI (High-Definition Multimedia Interface) Front Input connector: Connect an HDMI-capable source component that will be used only temporarily, such as a camcorder or game console, here. Resolution button: Press this button to access the AVRs video output resolution setting: 480i, 480p, 720p,

33、 1080i, 1080p or 1080p/24Hz. Use the Up/Down and OK buttons to change the setting.IMPORTANT NOTE: If you set the AVRs video output resolution higher than the capabilities of the actual connection between the AVR and your TV or video display, you will not see a picture. If you are using the composite

34、 video connection from the AVR to your TV (see Connect Your TV or Video Display, on page 17), press the Resolution button and use the Up/Down and OK buttons to change the resolution to 480i.Audio Effects button: Press this button to access the Audio Effects submenu, which allows you to adjust the AV

35、Rs tone controls and other audio controls. See Set Up Your Sources, on page 26, for more information.Video Modes button: Press this button for direct access to the Video Modes submenu, which contains settings you can use to improve the video picture. Use the OK button to scroll through the different

36、 modes, and use the Up/Down and Left/Right buttons to make adjustments within each mode. See Set Up Your Sources, on page 26, for more information.Surround Modes button: Press this button to select a listening mode. The Surround Modes menu will appear on screen, and the menu line will appear in the

37、front-panel display. Use the Up/Down buttons to change the surround-mode category and the Left/Right buttons to change the surround mode for that category. See Set Up Your Sources, on page 26, for more information.Back/Exit button: Press this button to return to the previous menu or to exit the menu

A signal is available at this output whenever an analog au

41、dio source is playing.HDMI Monitor Out connector: If your TV has an HDMI connector, use an HDMI cable (not included) to connect it to the AVRs HDMI Monitor Out connector. The AVR will automatically transcode component and composite video input signals to the HDMI format (upscaling to as high as 1080

42、p), so you do not need to make any other connections to your TV from the AVR or from any of your video source devices.Notes on using the HDMI Monitor Out connector: When connecting a DVI-equipped display to the HDMI Monitor Out connector, use an HDMI-to-DVI adapter and make a separate audio connecti

43、on. Make sure the HDMI-equipped display is HDCP (High-bandwidth Digital Content Protection)-compliant. If it isnt, do not connect it via an HDMI connection; use an analog video connection instead and make a separate audio connection.HDMI Input connectors: An HDMI connection transmits digital audio a

44、nd 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 and digital audio signals, you do not have to make any additional audio connections for device

45、s you connect via the HDMI connection. See Connect Your Audio and Video Source Devices, on page 18, for more information.Composite Video Input connectors: Use composite video connectors for video source devices that dont have HDMI or component video connectors. You will also need to make an audio co
