DAB (Digital Audio Broadcasting) is the next generation of radio.
DAB uses digital compression techniques to transform the source material, i.e. music and speech,
into digital code before it is transmitted. The code consists of electronic ‘ones and zeros’ called binary
digits or bits. The binary code is then multiplexed or grouped together to create a superior signal, when
compared with the older analogue system, with the following key bene ts:
Near CD quality sound.
Because DAB is binary coded, the receiving equipment is only expecting to receive a series of ones
and zeros, so any other interference is ignored, resulting in very high quality audio.
Interference free reception.
Analogue systems suffer from an effect called ‘multipath distortion’. This is caused because waves
do not behave in an orderly fashion, but bounce and reflect off buildings etc. DAB sees this as an
advantage and uses the direct and reflected signals to actually reinforce the end result.
No need to re-tune.
A single DAB frequency can be used to cover the whole of the UK, so solving many of the
problems experienced with the earlier analogue system. DAB can automatically tune-in all of the
available stations in your area.

Manual Tune Dynamic Range Control
DRC adds or removes a degree of compression
to compensate for the differences in the
dynamic range between radio stations. For
example, a station broadcasting popular
music may have a high level of compression
applied since the emphasis is on a constant
high listening level, whereas a station
broadcasting classical music will have little or
no compression as the listener requires all of
the highs and lows in the music to de ne the
detail.
There are three levels of compression:
DRC 0 No compression applied.
DRC 1 Maximum compression applied (this
is the default).
DRC 1/2 Medium compression applied.
The best way to determine which of these
settings suits you best is to experiment with
them on a variety of source material.
1. Press the MENU button to access the
menu control.
2. Press either the or button until ‘DRC
value’ is displayed.
3. Press the SELECT button to access
‘DRC value’. The current DRC level will
be displayed on line 2 of the display.
4. Press the button to select between
the three DRC values. The available
options appear on line 3 of the display.
5. When the required DRC value is
displayed press SELECT to con rm. You
should be able to hear the difference in
compression immediately.

Troubleshooting
If you believe that something is wrong with
your DAB digital radio, rst check the points
listed below.
There is no sound from my radio
Check that the volume is not set to the
minimum.
Make sure that the radio has been able to
locate DAB/AM/FM stations.
The display shows ‘NO SERVICES
AVAILABLE’ in DAB mode
Make sure that DAB coverage exists in your
area.
Try adjusting the position of the aerial or
location of the radio.
Poor reception
As with any radio service, there will be areas
of weak signal that may cause poor reception.
Follow the instructions for Manual Tuning on
page 16 and adjust the aerial while monitoring
the signal strength until the optimum signal
is obtained. If reception is still poor, try re-
locating the radio to another part of the room.
I cannot access secondary services
At the time of publishing this manual not many
secondary services are available in the UK.
This will increase as more DAB stations start
broadcasting. If a secondary service station is
available, the secondary indicator ‘>>’ will be
displayed next to the station name.
The display has gone blank or says
‘SERVICE OFF AIR’
This may occur if a broadcaster changes the
label of a service or removes a label whilst you
are listening to the station. The radio will try to
re-tune to the station. Alternatively, perform a
scan by pressing the AUTO button.
I cannot hear the station I have selected
The station you are listening to is displayed on
line 2. Line 3 shows the selected option, but
you have to press the SELECT button to tune
to the selected station.
I hear distortion on some stations
This is due to a weak signal. Try re-positioning
the aerial to gain maximum signal strength.
If the trouble persists, consult your dealer or
contact the Customer Helpline.
