06 Infotainment Radio mode only. The main FM channel will be displayed as, for example, 93.9 WNYC (Volvo uses the symbol ">" to indicate there are sub-channels available) The subFM channels will be displayed as 93.9 - 2 WNYC, 93.9 - 3 WNYC, etc. NOTE There may be a noticeable difference in sound quality when a change from analogue to digital or digital to analogue occurs, such as: 3. Turn TUNE and move the marker to HD Radio. 4. Press OK/MENU to turn HD off (the X will disappear from the box on the display screen). This will disable the radio's capability to receive digital broadcasts but it will continue to function as a conventional (analogue) AM/FM receiver. Please note that when HD is switched off, it will not be possible to tune to sub-channels (see the following section for a more detailed explanation of sub-channels). Repeat steps 2-4 above to reactivate HD (an X will appear in the box on the display screen). Please note that this will only switch HD on or off for the selected waveband (AM, FM1, etc.). • Reception coverage area: Due to current IBOC transmitter power limitations, the reception coverage area in digital mode is somewhat more limited than the station's analogue coverage area. Please be aware that as with any radio broadcast technology, terrain, time of day, foliage level and building location can have positive or negative effects on radio reception. • • • Volume increase or decrease Equalizer settings, i.e., Bass/ Midrange/ Treble cut or boost Time alignment (Digital program material in extreme cases can be as much as 8 seconds behind the analogue). This will noticeable as a "stuttering" effect. • Analogue to digital/digital to analogue blending: Analogue to digital blending will occur as the signal strength reaches a preset threshold in the receiver. This will be noticeable in fringe areas (areas with weak reception) and is normal. The above items are dependant on the broadcaster's equipment settings and do not indicate a fault in the vehicle's radio receiver or antenna systems. Switching HD on or off The factory setting for HD radio is off. If activated when driving through areas with weak HD signals (fringe areas), you may experience that the radio repeatedly switches between analogue/digital and digital/analogue reception. If this happens, it may be desirable to switch HD off. To do so: 1. Be sure the infotainment system is switched on and in one of the AM or FM modes. 2. Press OK/MENU in the center console control panel. Sub-channels 06 Example of an HD Radio station with sub-channels 225
