Leakage-current or resistance measurements must be made to determine that exposed parts are acceptablyinsulated from the supply circuit b
5、efore 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 andse
6、miconductor 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
7、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 c
8、onductive 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 gene
9、rate 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 replac
10、ementES 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
11、 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 l
12、ifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES devices.CAUTION : Harman KardonAVR 365/230V Service ManualPage 2 of 176RadioFans.CN 收音机爱 好者资料库AVR4Front-Panel ControlsFront-Panel ControlsContinued on next pagepower Indicatormessage displayvolume kn

15、he Avr is turned on. IMPORTANT NOTE: 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
16、metal). If a short-circuit is not 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 men
17、u.Info button: press this button to access the Avrs Source submenu, which contains the settings for the source currently playing. use the up/down buttons to scroll through the different settings.Message display: various messages appear in this two-line display in response to commands and changes in
18、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.IR sensor: this sensor receives infrared (Ir) commands from th
19、e remote control. It is important 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
20、 buttons: use these buttons to navigate 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
21、to do so as part of an upgrade procedure.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 res
22、olution setting: 480i, 480p, 720p, 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 pictu

If you are using the composite 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,
24、 which allows you to adjust the Avrs 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 butt
