When the receiver is turned on, the LED turns blue.
Source Select: Press this button to select a source device, which is a component where a playback signal originates, e.g., DVD, CD, cable TV, satellite or HDTV tuner.
Source Indicators: The name of the current source input lights up. The indicated input changes each time the Source Select button is pressed.
Volume Knob: Turn this knob to raise or lower the volume, which will be shown in decibels (dB) in the Message Display.
Message Display: Various messages appear in this
Tuner Band: Press this button to select the tuner as the source, to switch between the AM and FM bands, or to select XM satellite radio.
Tuning: Press either side of this button to tune a radio station or XM channel.
Tuning Mode: This button toggles between manual (one frequency step at a time) and automatic (seeks frequencies with acceptable signal strength) tuning mode. It also toggles between stereo and mono modes when an FM station is tuned.
When XM Radio is in use, pressing this button repeatedly displays the channel name, category, artist and track title in the lower line of the Message Display. For
Preset Stations: Press this button to select a preset radio station.
Headphone Jack/EzSet/EQ Microphone Input: Plug a 1/4" headphone plug into this jack for private listening.
This jack is also used to connect the supplied microphone before begin- ning the EzSet/EQ procedure described in the Initial Setup section. To begin EzSet/EQ, plug the supplied microphone into this jack, place the microphone at the listening position, and follow the directions given in the Speaker
Surround Mode: Press this button to select a surround sound (e.g., multichannel) mode group. Choose from the Dolby modes, DTS modes, Logic 7 modes, DSP modes or Stereo modes.
Surround Select: After you have selected the desired surround mode group, press this button to select a specific mode.
Surround Mode Indicators: One or more of these icons may light up as you select different surround modes. The Message Display also indicates the surround mode.
Analog Audio, Video and Digital Audio Inputs: Connect a source component that will only be used temporarily, such as a camera or game console, to these jacks. Use only one type of audio and one type of video connection.
Speaker/Channel Input Indicators: The box icons indicate which speaker positions you have configured, and the size (frequency range) of each speaker. When a digital audio input is used, letters will light inside the boxes to indicate which channels are present in the incoming signal.

Digital Input Select: Press this button to select the specific digital audio input (or analog audio input) you used for the current source.
Delay: Press this button to set delay times that compensate for placing the speakers at different distances from the listening position.
Remote IR Sensor: This sensor receives infrared (IR) commands from the remote control. It is important to ensure that it is not blocked. If covering the sensor is unavoidable, such as when the AVR 247 is placed inside a cabinet, you may use an optional Harman Kardon
HE 1000, or other infrared receiver, connecting it to the Remote IR Input on the AVR 247’s rear panel. Alternatively, connect the Remote IR Output of another compatible component to the AVR 247’s Remote IR Input. Point the remote at the other device’s remote sensor, and the command will be transmitted to the AVR 247. An external IR “blaster” may also be used, positioned to point at this area.
