Components identified with the IEC symbolin the parts list are special significance to safety. 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 exposed 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 devices 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 assembly, 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 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 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 protective 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 replacement 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. (Otherwise 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.

A signal is available at this output whenever an analog audio 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 1080p), 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 connection. 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 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 additional audio connections for devices 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 connection from the source device to the Avr. See connect your Audio and video Source devices, on page 18, for more information. Digital Audio Input connectors: 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 Audio and video Source devices, on page 18, for more information.
