If you are having difficulty accessing these sources,check the Network Settings. Highlight the Network Settings line andpress the OK Button to view the Network Settings submenu.• ID #: This line is informational only, and identifies the AVRto other devices on your home network and the Internet forwww.radioharmankardon.com.• Network Settings: If leaving this setting at “Automatic”does not allow access, press the OK Button to change it to“Manual” and adjust the other settings below it.• IP Address, Subnet Mask, Gateway, PrimaryDNS, Secondary DNS: Depending on your system, thisinformation may be set automatically and may change eachtime the AVR accesses the network for a new listening session.Contact your ISP for this information.• Proxy Address and Proxy Port: Some network securitysystems access the Internet using a proxy server. Sometimesfilling in just this information correctly may resolve Internetaccess issues.Volume Units: Select whether volume is displayed in theconventional decibel scale or on a numeric scale from 0 to 90.When the decibel scale is used, 0dB is the maximum recommendedvolume, with lower volumes displayed as negative values.Volume Default and Volume Default Level: These twosettings are used together to program the volume level at turn-on.Turn Volume Default on, and then set the Volume Default Level tothe desired turn-on volume. When the Volume Default setting is leftoff, the AVR will play at the last-used volume setting from the previ-ous listening session.Unit of Measure: Adjusts the speaker-distance settings forManual Speaker Setup. Select between meters and feet.Language: Select the preferred language for the AVR’s on-screenmenus and displays: English, French, Spanish, German, Italian orRussian.HDMI Audio to TV: Determines whether HDMI audio signalsare passed through the HDMI Output to the video display. In normaloperation, leave this setting Off, as audio will be played through theAVR. To use the TV by itself, without the home theater system, turnthis setting On. Mute the TV’s speakers when using the AVR for audio.Dolby Volume Calibration: This setting determines theDolby Volume Calibration Offset, as described on page 33. Itsdefault of 0dB is best when the system’s loudspeakers have asensitivity rating of 88dB (8 ohms, 1 watt, 1 meter). If your loud-speakers have a higher sensitivity rating, increase the Dolby VolumeCalibration setting by the difference between your speakers’ sensi-tivity and 88dB. If your speakers have a lower sensitivity, decreasethe Dolby Volume Calibration setting by the difference between88dB and your speakers’ sensitivity.Menu AppearanceMenu Transparency: Select whether video programs willbe visible when the menu system is in use. Select Normal for a fullytransparent background, Medium for partial transparency or Opaqueto block video programs while the menus are on screen.Volume Status Messages: When the AVR is turned on,the volume is adjusted or the source is changed, or if a change inthe input signal is detected, a status message will be displayed onscreen. Select how long the message remains visible, from 2 to10 seconds, with a default of 3 seconds. Select “Off” if you do notwish to see the status messages.Menus: The settings in the Surround Modes, Video Modes andAudio Effects menus only remain in effect during the current listeningsession. This setting governs how long these menus remain visibleafter the last adjustment: 5, 10 or 30 seconds, 1 minute or 5 min-utes. Select “No Time-Out” to view the menus indefinitely, but thissetting is not recommended, due to the danger of “burn-in” onsome video displays.Setup and Slide-In Menus: This setting determines howlong the setup menus (Main Menu, Speaker Setup Menu, Zone 2Menu, all slide-in menus) remain visible after the last adjustment.Select a time-out period of 5, 10 or 15 (the default) minutes, or notime-out, which leaves the menus on screen until manually cleared.A time-out period avoids the possibility of burn-in damage to plas-ma or CRT displays.Screen Saver: Program a time-out period for no activity (withno menus displayed) before the AVR’s built-in screen saver begins.Select a period of 5, 10, 20 or 30 minutes or 1 hour, or turn off thescreen saver. A time-out period avoids the possibility of burn-indamage to plasma or CRT displays.System InformationSoftware Version: This line is informational only.
