Tuning the radio from the FM source display

Your Lifestyle® music system has a built-in AM/FM radio. Good AM/FM radio reception depends on the location and orientation of the AM and FM antennas. See “FM antenna connections” and “AM antenna connections” on page 12 for proper antenna installation. See “Optimizing AM/FM radio reception” on page 28 for help with antenna adjustment.

Turning the system on and choosing the radio

Press FM or AM to turn your system on to the most recently selected FM or AM station. If the system is already on, use the FM or AM button to select either of these sources.

Setting radio channel spacing

On some multi-room interfaces, the AM and FM channel spacing can be set for North America (US: 10 kHz for AM and 200 kHz for FM) or Europe (EU: 9 kHz for AM and 50 kHz for FM). Select the channel spacing most appropriate for your area.

To change between US and EU channel spacing, press and hold the SOURCE button for two seconds. Press either arrow button until tunr appears. Using the arrow buttons, select US or EU. Press DONE to exit.

Selecting FM or AM

Press the FM or AM SOURCE button to turn on the radio band desired. Select a station by tuning manually, seeking a strong station, or selecting a preset station.

Manually tuning a radio station

To manually tune a radio station, press the (decrease) or (increase) arrow button on either side of the frequency display to change the frequency in small steps (Figure 20). Or, press the KEYPAD button until the indicator arrow points toward TUNE. Then use the number buttons to enter the frequency of the station you want to tune. The left-most digit is entered first and the display flashes while you enter more digits. When you have entered the station frequency, the system selects that station or the closest valid station.

To tune a station, use up/down arrow keys, or

point the KEYPAD to TUNE and enter numbers.

Receiving FM stereo or monaural broadcasts

When receiving sufficiently strong FM stereo broadcast signals, the radio automatically receives in the stereo mode; the STEREO indicator appears on the display. Weak stereo signals are received in the monoaural mode (the STEREO indicator is off).

To force the tuner to receive in stereo mode only, press and hold the center of the station display until you hear a high-pitched beep. To receive in monaural mode only, press and hold until you hear a low-pitched beep. However, even though you may have forced the stereo mode, monaural broadcast material is still heard in monaural. Retuning the station cancels any forcing.
