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 the parts list in this manual. Leakage-current or resistance measurements must be made to determine that e

5、xposed parts are acceptably insulated 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 called Electrostatically Sensitive (ES) Devices. Examples of typical ES device

6、s are integrated circuits and some field effect transistors and semiconductor 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 a

7、ssembly, drain off any electrostatic charge on your 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

8、electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to 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

9、device. Some solder removal devices not classified as anti-static can generate electrical charges sufficient 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 protecti

10、ve package until immediately before you are ready to install it. (Most replacement ES 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 replace

11、ment ES device, touch the protective material to the chassis 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. (Othe

12、rwise harmless motion such as the brushing together or your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES devices.

HDMI Monitor Out connector: If your tV has an hdM

31、I 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 the hdMI Monitor out connector, use an hdMI-to-dVI adapter

32、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 analogue video connection instead and make a separate audio connection. HDMI Input connectors: the hdMI (high-definition Multimedia Interface) feature is a conn

33、ection 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 and digital audio signals, you do not have to make any

34、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 your tV does have an hdMI connector but you are conn

35、ecting 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: If your blu-ray disc or dVd player does not have an

36、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 non-hdMI source devices have digital outputs, conn

37、ect 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 analogue video recorders video input connector to the AVrs V

38、ideo 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 Analogue output connectors to the analogue video recorders audio inputs. Composite Video Input connectors: use composite video connectors fo

39、r 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. Subwoofer connector: connect this jack to a powered subwoofer with a line-lev

40、el input. See connect Your Subwoofer, on page 13, for more information. Analogue Audio Input/Output connectors: use the AVrs Analogue Audio Input/output connectors for source devices that dont have hdMI or digital audio connectors. use the Video 2 out and tape out connectors to connect to the audio

41、inputs of a Vcr and tape deck. See connect Your Source devices, on page 13, for more information. Speaker connectors: use two-conductor speaker wire to connect each set of terminals to the correct speaker. See connect Your Speakers, on page 13, for more information. Main Power switch: this mechanica

42、l switch turns the AVrs power supply on or off. It is usually left on and cannot be turned on or off using the remote control. 12V Trigger connector: this connector provides 12V dc whenever the AVr is on. It can be used to turn on and off other devices such as a powered subwoofer. AC Input connector

47、ns, continued In addition to controlling the AVr, the AVr remote is capable of controlling eight other devices. during the installation process, you may program the codes for each of your source components into the remote. (See program the remote to control Your Source devices and tV, on page 16, fo

48、r programming information.) to operate a component, press its Source Selector button to change the remotes control mode. A buttons function depends on which component is being controlled. See table A10 in the Appendix for listings of the functions for each type of component. Most of the buttons on t

49、he remote have dedicated functions, although the precise codes transmitted vary depending on the specific device being controlled. due to the wide variety of functions for various source devices, we have included only a few of the most often-used functions on the remote: alphanumeric keys, transport controls, television-channel control, menu access and power on and off. to return the remote to the AVr control mode at any time, press the
