OPERATIONNow that you have installed your system components and completed atleast a basic configuration of your receiver, you are ready to beginenjoying your home theater system.Turning On the AVR 247Gently press the Master Power Switch until the word OFF is no longer visi-ble. The Power Indicator above the two power switches should light up inamber. This indicates that the AVR is in Standby mode and is ready to beturned on. Normally, you may leave the Master Power Switch in the ONposition, even when the receiver is not being used. See Figure 58.Figure 58 – Power SwitchesThere are several ways in which the AVR 247 may be turned on:a) Press the Standby/On Switch on the front panel. See Figure 58.b) Press the Source Select Button on the front panel. See Figure 59.Figure 59 – Source Select Buttonc) Using the remote, press any one of these buttons: AVR, DVD/CD,TAPE/The Bridge, HDMI 1/HDMI 2, VID1, VID2, VID3, VID4, XM,AM/FM, 6/8CH. See Figure 60.Figure 60 – AVR and Input SelectorsNOTE: Any time you press one of the remote’s Input Selectors(i.e., DVD/CD, TAPE/The Bridge, XM, VID1, VID2, VID3, VID4 orHDMI 1/HDMI 2), the remote will switch modes so that it willonly operate that device. To control the receiver, press the AVRButton to return the remote to AVR mode.To turn the receiver off, press either the Standby/On Switch on the frontpanel, or press the AVR Button and the OFF Button on the remote.Unless the receiver will not be used for an extended period of time (forexample, if you will be on vacation), it is not necessary to turn off theMaster Power Switch. When the Master Power Switch is turned off, anysettings you have programmed, including system configuration andpreset radio stations, will be preserved for up to four weeks.Sleep TimerYou may program the AVR to play for up to 90 minutes and then turnoff automatically using the sleep timer.Press the Sleep Button on the remote, and the time until turn-off will bedisplayed. See Figure 61. Each additional press of the Sleep Button willreduce the time until turn-off by 10 minutes, until the OFF setting isreached, which disables the sleep timer.Figure 61 – Sleep ButtonWhen the sleep timer has been set, the front-panel display will automati-cally dim to half-brightness. If you press any button on the remote orfront panel, the display will return to full-brightness. The display will dimagain several seconds after your last command.If you press the Sleep Button after the timer has been set, the remainingtime until turn-off will be displayed. You may press the Sleep Button tochange the time until turn-off. Pressing and holding the Sleep Button willdisable the sleep timer, and the SLEEP OFF message will appear.Volume ControlThe volume may be adjusted either by turning the knob on the frontpanel (clockwise to increase volume or counterclockwise to decreasevolume), or by pressing the Volume Control Buttons on the remote.See Figure 62. The volume is displayed as a negative number ofdecibels (dB) below the 0dB reference point, and may be changedin 0.5dB increments.Unlike the volume controls on some other products, 0dB is the maximumvolume for the AVR 247. Although it’s physically possible to turn thevolume to a higher level, doing so may damage your hearing and yourspeakers. For certain more dynamic audio materials, even 0dB may betoo high, allowing for damage to equipment.Figure 62 – Volume ControlsThe AVR 247 is designed to reproduce audio with a minimum amountof distortion, which may lead you to think that your hearing and theequipment can handle higher volumes. We urge caution with regard tovolume levels.Mute FunctionTo temporarily mute all speakers and the headphones, press the MuteButton on the remote. See Figure 63. Any recording in progress will notbe affected. The MUTE message will flash in the display as a reminder.26AVR247 harman/kardon
