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.

HDMI Monitor Out connector: If your tV has an hdMI 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 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 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 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 connector, or if your tV does have an hdMI connector but you are connecting 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 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, 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: connect an analogue 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 Analogue output connectors to the analogue video recorders audio inputs.
