46 OPERATIONOperationAfter a period of time the screen may disappearfrom view. The length of time is set using theFull-OSD Time Out setting in the System Settingsmenu (described in the Advanced Functions sec-tion). You may restore the Now Playing screen toview by pressing either of the ‹/› ButtonsE, and you may then navigate the menusas explained above.NOTE: It is strongly recommended that you usea screen saver built into your video display toavoid possible damage from “burn-in” that mayoccur with plasma and many CRT displays whena still image, such as a menu screen, remains ondisplay for an extended period of time.Output Level AdjustmentWith Source SignalsNormal output level adjustment for theAVR is established using the test tone, as out-lined on page 35. In some cases, however, it maybe desirable to adjust the output levels usingprogram material such as a test disc, or a selec-tion you are familiar with. Additionally, the out-put level for the subwoofer and those for theStereo modes can only be adjusted using thisprocedure.To adjust the output levels using program mate-rial, first select the surround mode for which youwant to trim the speakers (see NOTE below),start your program material source and set thereference volume for the front left and frontright channels using the Volume Control .Once the reference level has been set, press theChannel Select button CÙ and note thatFRONT L LEVEL will appear in the MainInformation Display Ò. To change the level,first press the Set button F @, and then usethe Selector buttons 7 or the ⁄/ ¤ buttonsD to raise or lower the level. DO NOT use thevolume control, as this will alter the referencesetting.Once the change has been made, press the Setbutton F @ and then press the Selectorbuttons 7 or the ⁄/¤ buttons D to selectthe next output channel location that you wishto adjust. To adjust the subwoofer level, pressthe Selector buttons 7 or the ⁄/¤ buttonsD until WOOFER LEVEL appears in theMain Information Display Ò or on-screendisplay (only available if the subwoofer is turnedon).Press the Set button F @ when the name ofthe desired channel appears in the MainInformation Display Ò and on-screen dis-play, and follow the instructions shown above toadjust the level.Repeat the procedure as needed until all chan-nels requiring adjustment have been set. Whenall adjustments have been made and no furtheradjustments are made for five seconds, the AVRwill return to normal operation.The channel output may also be adjusted usingthe full-OSD on-screen menu system. First, setthe volume to a comfortable listening level usingthe Volume Control ı. Then, press theOSD button L to bring up the main menu(Figure 1). Press the ¤ Button D twice untilthe Speaker -tab is highlighted in white.Press the Set Button F to access the menu,and a second time to activate the ManualConfiguration line. Now use the ⁄/¤D to scroll to the C h Adjust line andpress the Set Button F to display the C hAdjust submenu.Figure 29When the menu appears, the internal test tonewill be turned off. This will allow you to use yourexternal test disc or other source material as thetest signal. Press the Set Button F and usethe ⁄/¤ Buttons D to select the channelsto be adjusted. At each channel position pressthe Set Button F followed by the ‹ /›Buttons E to change the output level.Remember, when you are using a disc with testsignal (e.g. pink noise) or an external signalgenerator as the source, the goal is to have theoutput level at each channel be equal whenheard at the listening position, with any sur-round mode selected. When your test source is anormal disc with music signals, you may adjustthe level for each channel and surround mode asyou prefer, e.g. you may lower the center chan-nel level when you find it to be too high orincrease the level of the rears when you find itto be too low with specific surround modes.If you wish to reset all the levels to their originalfactory default of 0dB offset, press the ⁄/¤Buttons D so that the blue cursor bar ishighlighting the RESET line and press the SetButton F. After the levels are reset, resumethe procedure outlined above to reset the levelsto the desired settings. When all adjustments aredone, press the ‹ Button E consecutivetimes to move back to the main menu to makeother adjustments. If you have no other adjust-ments to make, press the OSD Button L toexit the menu system.NOTE: The output levels may be separatelytrimmed for each digital and analog surroundmode. If you wish to have different trim levels for aspecific mode, select that mode and then followthe instructions in the steps shown above.With Stereo modes the adjustment proceduredescribed above is the only way to trim the out-put level, e.g. to match the Stereo level withother modes.Dim FunctionSince the AVR will often be used when movies orother video programming is viewed under low-light conditions, you may wish to lower thebrightness of the front-panel displays and indica-tors so that they do not distract from the videopresentation. You may dim the displays using themenu system, as shown on page 49, or you maycontrol the brightness directly from the remote.Simply press the Dim Button once to dimthe front panel to half the normal brightnesslevel; press it again to turn the displays off. Notethat when the displays are dimmed or turned off,the blue lighting above the Standby/On Switch2 will continue to stay lit as a reminder that theAVR is still turned on.Note that all changes to the front-panel bright-ness level are temporary; the displays will returnto full brightness after the AVR is turned off andthen on again. To return the displays to fullbrightness without turning the unit off, press theDim Button as needed until the displaysare on.In addition to lowering the brightness of the dis-plays or turning them off completely, you maywish to have them appear whenever a button onthe remote or front panel is pushed, and thengradually fade out after a set time period. Youmay do this by making the appropriate settingsin the VFD Fade Timeout line of theSYSTEM SETUP menu, as shown onpage 49.Memory BackupThis product is equipped with a memory backupsystem that preserves tuner presets and systemconfiguration information if the unit is turned offcompletely, accidentally unplugged or subjectedto a power outage. This memory will last forapproximately two weeks, after which time allinformation must be reentered.
