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 semi

5、conductor (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

6、 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

7、 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 e

8、lectrostatic 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 devic

9、es.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

10、 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

11、power is applied to the chassis or circuit, and observe all other safety precautions.8. Minimize bodily motions when handling unpackaged replacement ES devices.

Notes on using the HDMI Monitor Out connector: When connecting a DVI-equippe

40、d display to the 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 connecto

41、rs: The HDMI (High-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

42、digital video and 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 c

DVD Component Video I

44、nput connector: 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 con

45、nectors: If your 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: Conne

46、ct an analog video 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.Composit

47、e 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 connection from the source device to the AVR. See Connect Your Source Devices, on page 13, for more information.IR Remote In/Out co

48、nnectors: When the 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 AV

49、R. See Connect IR Equipment, on page 15, for more information.The Bridge IIIP connector: Connect an optional Harman Kardon The Bridge IIIP docking station to this connector.
