DAB
DAB stands for digital audio broadcasting. It is a new form of radio
that is broadcast digitally. Unlike regular analogue broadcasting,
digital radio deteriorates less, and is thus able to provide quality
sound close to that of a disc.

Bands
There are two types of DAB bands, “BAND
III
” (Receivable in this
unit) and “L BAND”(Not broadcast in the United Kingdom, and not
receivable on this unit).
Frequencies
There are 41 frequencies on BAND
III
. Among those frequencies,
7 are used in the United Kingdom (current as of December, 2007).
Ensemble, station and service
The number of stations that make up one frequency differ between
DAB and analogue radio. Analogue stations all broadcast on different
frequencies, even if it is the same company doing the broadcasting.
With DAB however, it is possible to broadcast a number of stations
on the same frequency.
In DAB terminology, a group of stations on the same frequency is
called an ensemble.
As shown in the diagram, an ensemble consists of a group of stations
which have primary services, they can also have secondary services.
This means, for example, that commentary on sports events from
different areas can all be broadcast at once.
DAB reception method on this unit
DAB reception method on this unit
Depending on the region there is a difference between broadcast
frequency and stations broadcast along the same frequency. For this
reason, a memory of receivable stations should fi rst be created and
then select from those memorized stations as the reception method.
DAB Auto Scan
This function searches for currently receivable stations and inputs
them into unit memory.
When DAB is selected for the fi
rst time, this function starts
automatically.
Note
Even if the station is stored into memory, some stations may not
broadcast depending on the time of day etc. If this occurs, “NO
SERVICE” is displayed.
Station Memory Updating
When there is a station name change, or a new station begins
broadcasting, the unit memory is automatically updated when:
• The previous station name is displayed by selecting “STATION
TUNE”.
• One of the stations already broadcasting on the same frequency
with the new station is displayed by selecting “STATION TUNE”.
Note
• Deleting stations that are no longer broadcasting is not automatic. If
you want to delete a station, perform Auto scan again and the new
memory is created.
• When a new frequency begins broadcasting, stations on that new
frequency are not automatically added to memory. Perform Auto
scan to add them to memory. Also, you may need to change the
Auto scan range if the new frequency is outside the factory set Auto
scan range (
➡
page 11).
STATION TUNE
You can select stations from the memory created as shown above in
alphanumeric order. You can easily select your favorite stations by
using presets (
