Selecting sub-channels
To listen to a station's sub-channel(s), tap the
station on the screen or press the forward/back
arrow keys on the right-side steering wheel key-
pad or below the screen.
Sub-channels can also be stored as favorites, see
the article "Changing and searching for radio sta-
tions".
If you tap a sub-channel favorite, it may take up
to
6 seconds
before the channel becomes audi-
ble. If you tap a station while you are out of digital
range of the transmitter,
No reception

HD Radio limitations
Limitations
•
Main channel vs. sub-channels (FM only)
:
The main channel is the only channel that
can receive in hybrid mode (both digital and
analogue). If a frequency has sub-channels,
they are broadcast in digital mode only. The
main FM channel will be displayed as, for
example, "WRIF-FM HD1". The sub-FM
channels will be displayed as"WRIF-FM
HD2", "WRIF-FM HD3", 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.
•
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 noticea-
ble in fringe areas (areas with weak recep-
tion) 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 material
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
.
