strength), the receiver will determine
which signal to receive.
Limitations
•
Main channel vs. sub-channels (FM
only) : The main channel is the only chan-
nel that can receive in hybrid mode (both
digital and analogue). If a frequency has
sub-channels, they are broadcast in digi-
tal 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 cur-
rent 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 posi-
tive or negative effects on radio recep-
tion.
•
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.
NOTE
There may be a noticeable difference in
sound quality when a change from ana-
logue to digital or digital to analogue
occurs, such as:
•
Volume increase or decrease
•
Equalizer settings, i.e., Bass/ Mid-
range/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 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.).
