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 160/230 Service Manual2 of 116RadioFans.CN 收音机爱 好者资料库7L - Audio - RRDSChannelDigitalSetTuningSurr.

Standby : Amber indicates that the AVR is ready to be turned on.On : When the AVR is turned on, this LED turns white.NOTE: If the PROTECT message ever appears, turn off the AVR and unplug it. Check all speaker wires for a possible short. If none is found, bring the unit to an authorized Harman Kardon service center for inspection and repair before using it again.Standby/On Switch: This electrical switch turns the receiver on, or places it in Standby mode for quick turn-on.RDS: Activates RDS functions for FM RadioChannel Level Control: Press this button to adjust the output level for any amplifier channel. It may be necessary to raise or lower the level of a specific channel to compensate for the placement of the relevant speaker in the room in relation to the listening position; e.g., the center channel speaker is further away from the listening position than the front left and right speakers, so that the dialogue is too soft to hear clearly.To adjust the level of a channel, press this button once. If the desired channel is not displayed on screen and in the front-panel Message Display, use the Tuning Buttons to scroll to it. When the desired channel appears, use the M N Navigation Buttons to change the level.It is recommended that you avoid changing the channel levels after you have run the EzSet/EQ setup procedure described in the Initial Setup section, which properly adjusts all channel levels. See the Advanced Functions section for more information on manual speaker setup, including level adjustment.Remote IR Sensor: This sensor receives infrared (IR) commands from the remote control. It is important to ensure that it is not blocked. If covering the sensor is unavoidable, use an optional Harman Kardon HE 1000, or other infrared receiver, connecting it to the Remote IR Input on the AVR 160s rear panel.Digital Input: To change the audio input for the current source to one of the six digital audio inputs or the analog input for the source, press this button and use the M N Navigation Buttons to change the input. Although any digital audio input may be assigned to any source, the analog audio inputs are all permanently dedicated to the source with which they are labeled.M N Navigation: These buttons are used to navigate the AVRs menus.Set: Press this button to select the currently highlighted item.Message Display: Various messages appear in this two-line display in response to commands and changes in the incoming signal. In normal operation, the current source name appears on the upper line, while the surround mode is displayed on the lower line. When the on-screen display menu system (OSD) is in use, the current menu settings appear.Tuning: Press these buttons to tune a radio station.harman/kardonAVR 160/230 Service Manual3 of 1169ENGLISHComponent Video Monitor OutputComponent 1& 2 InputsHDMI Monitor OutputHDMI 1-3 Inputs6-/8-Channel Analog Audio InputsCoaxial 1 & 2 Digital Audio InputsVideo 2 Audio/Video InputsDVD Audio/ Video InputsVideo Monitor OutputVideo 1 Audio/ Video Inputs & OutputsAC Power CordSubwoofer OutputFront Speaker OutputsSurround Back Speaker OutputsSurround Speaker OutputsOptical 1&2 Digital Audio InputsTape Audio Inputs & OutputsCenter Speaker OutputsCoaxial Digital Audio OutputMain Power SwitchFM AntennaAM AntennaAUX InputCD InputsAM and FM Antenna Terminals: Connect the included AM and FM antennas to their respective terminals for radio reception.Component Video Monitor Output: If you are using one of the Component Video Inputs and your television or video display is component-video-capable, connect these jacks to the video display.NOTE: Due to copy-protection restrictions, there is no output at the Component Video Monitor Outputs for copy-protected sources.Component Video 1&2 Inputs: If a video source has analog component video (Y/Pb/Pr) capability, and if you are not using an HDMI connection, connect the component video outputs of the source to one of the sets of component video inputs. Do not make any other video connections to that source.NOTE: AVR 160 does not transcode composite video source signals to the component video format. Video Monitor Output: If any of your sources use composite video connections, connect this monitor output to the corresponding input on your video display. Composite video source signals are only available at this output.Video 1, Video 2 and DVD Audio/Video Inputs: These jacks may be used to connect your video-capable source components (e.g., Blu-ray Disc player, DVD player, cable TV box) to the receiver.NOTE: If a source is equipped with an HDMI output, it is preferable to connect it to one of the AVRs HDMI Inputs. If the source does not have an HDMI output, use its component or composite video output, and make a separate audio connection.Video 1 Audio/Video Outputs: These jacks may be used to connect your DVR, VCR or another recorder.HDMI Inputs and Output: HDMI (High-Definition Multimedia Interface) is a connection for transmitting digital audio and video signals between devices. Connect up to three HDMI-equipped source devices to the HDMI inputs using a single-cable connection.When you connect the HDMI Output to your video display, the AVR 160 will automatically transcode component video source signals to the HDMI format, but they will be passed through at the original resolution and will not be scaled. The AVRs on-screen menus are visible when the HDMI Output is used, but only at 576i resolution. The main video source will not be visible.NOTES: When connecting a DVI-equipped display to one of the HDMI Outputs:Use an HDMI-to-DVI adapter. Make sure the display is HDCP-compliant. If it isnt, do not connect it to an HDMI Output; use an analog video connection instead.Always make a separate audio connection.
