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 sub-
FM channels will be displayed as 93.9 – 2
WNYC, 93.9 - 3 WNYC, 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 technol-
ogy, terrain, time of day, foliage level and
building location can have positive or neg-
ative effects on radio reception.
• Analogue to digital/digital to analogue
blending: Analogue to digital blending will
occur as the signal strength reaches a pre-
set threshold in the receiver. This will be
noticeable in fringe areas (areas with weak
reception) and is normal.
NOTE
There may be a noticeable difference in
sound quality when a change from analogue
to digital or digital to analogue occurs, such
as:
• Volume increase or decrease
• Equalizer settings, i.e., Bass/ Midrange/
Treble cut or boost
• Time alignment (Digital program mate-
rial in extreme cases can be as much as
8 seconds behind the analogue). This
will noticeable as a "stuttering" effect.
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 acti-
vated when driving through areas with weak
HD signals (fringe areas), you may experience
that the radio repeatedly switches between
analogue/digital and digital/analogue recep-
tion. 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.
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 func-
tion as a conventional (analogue) AM/FM
receiver. Please note that when HD is switched
off, it will not be possible to tune to sub-chan-
nels (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.).
