HD radio HD RADIO™ TECHNOLOGY
HD Radio™ systems provide digital radio
broadcasts on AM/FM radio alongside the
analogue radio signals. HD Radio technology is
capable of providing improved audio quality
compared to the analogue broadcast.
The HD Radio digital signal is transmitted at the
same frequency as the analogue signal and can
also provide additional multicast channel
services where available.
To switch the HD Radio feature on and off:
• Select Settings from the radio Controls
menu (item 6 under 108, RADIO
CONTROLS).
• Select HD Off to deactivate or On to
activate HD Radio.

HD RADIO™ RECEIVER OPERATION
HD Radio™ technology operates in a very
similar way to the standard AM/FM system.
Information on storing stations, waveband
selection etc., is given under 108, RADIO
CONTROLS.
When an HD Radio signal is detected and
received, the tuner gradually blends
automatically between the analogue and the
digital audio.
Note: During this process, a change in volume
levels may be experienced. The volume
matching between the analogue and digital
signal is dependent upon the broadcaster.
If a digital signal is unavailable, the AM/FM
analogue signal is automatically selected. If the
signal is lost when listening to a multicast
service, the audio will be muted.
When tuned to an HD Radio channel, the
station name shown in the display, is prefixed
by HD. If there are multicast services available,
the station name will be prefixed by HD1.
TUNING TO MULTICAST SERVICES
Multicast services (extra digital audio
channels) can be received on HD Radio™
channel broadcasts. Their availability is
dependent upon the channel broadcaster. If an
HD Radio channel features multicast services,
HD1 will be displayed.
To access any available multicast services, use
the seek buttons on the audio unit. The
selected service (HD2, HD3 etc.) will be
displayed.
Note: If the last of the multicast stations is
passed when using the seek arrows, then the
next analogue station will be selected. There
will be a delay while the unit tunes to the next
available analogue frequency.
Multicast channels can be stored as presets
and used as normal. When recalling a multicast
preset, a short delay may be experienced
during which the audio is muted.
If the signal is lost when listening to a multicast
service, the audio will be muted.
POOR RECEPTION AND AUTO
SWITCHING
In areas of poor reception due to signal
masking and transmitter strengths, the HD
Radio™ system may switch between the HD
Radio primary signal and the corresponding
analogue broadcast more frequently. If tuned
to a multicast service, the audio may mute
more frequently.
If poor reception and auto switching becomes
unacceptable, it is recommended that HD is
switched off or the user tunes to an HD Radio
service with better coverage in their location.
