DAB & FM STATION PRESETS  
DAB SCANNING  
DAB and FM presets  
Your radio can store up to 10 of your favourite stations as  
presets on both the DAB and FM bands for quick recall.  
When first used, your radio scanned the DAB band for  
available stations. The station services found were then  
stored in your radio’s memory.  
You can re-scan the band at any time if you move to a different  
area or just to refresh the stored list of available stations.  
NOTE: On some occasions, when moving to a different area,  
re-scanning may not fully update the station list. In this case  
it may be necessary to reset your radio. (see the‘Factory reset’  
option on page 8).  
To store a preset 1-10  
Tune to the station you want to store as a preset.  
Press and hold the PRESET button.  
‘Preset Store’ will be displayed.  
Press the P or O button repeatedly to find the preset  
number you want to store.  
For each preset number the preset station currently stored will  
be displayed or ‘(Empty)’ if none is stored.  
To scan for DAB stations manually:  
Select the DAB band.  
Press the SCAN button.  
Press the VOLUME/SELECT control to confirm if you want  
to store the station in the displayed preset number.  
The scanning process will take a few minutes. The number of  
services found during the scan will be shown at the right side  
of the display.  
After the scan, the radio will re-tune to the last station playing  
if it is available. Alternatively, you can continue to browse for  
another station as described on the previous page.  
To recall any preset 1-10  
Press the PRESET button briefly.  
Press the P or O button repeatedly to find the preset  
number you want to play.

DAB DISPLAY MODES  
FM DISPLAY MODES  
DISPLAY MODE OPTIONS  
DLS (Dynamic Label Segment): This is a scrolling message  
giving real-time information - song titles, news headlines,  
etc.  
SIGNAL STRENGTH: This setting will display a signal  
strength bargraph. The longer the bargraph, the stronger the  
signal. Setting the display to show signal strength is useful  
when setting up the aerial for the strongest signal.  
PROGRAMME TYPE: This describes the style of the  
programme being broadcast.  
The bottom line of the display can be switched to show  
different items of information that may be transmitted with  
an FM station.  
The bottom line of the display can be switched to show  
different items of information that may be transmitted with  
a DAB station.  
To change the display mode:  
Press the INFO button repeatedly to change the information  
displayed while playing an FM radio station.  
The full range of display options are shown below. Some  
stations may not broadcast all of these options.  
Choosing the information display:  
Press the INFO button repeatedly to change the information  
displayed while playing a DAB radio station.  
The full range of display options are shown below. Some  
stations may not broadcast all of these options.  
MULTIPLEX NAME: DAB Digital radio stations are broadcast  
in multiplexes. Each multiplex is a bundle of radio stations  
transmitted in a single frequency. There are national and  
local multiplexes; local ones contain stations specific to your  
area. This option displays the name of the multiplex name  
that contains the station you are listening to.  
MULTIPLEX NUMBER/FREQ: This option will display the  
multiplex number and frequency that contains the station  
you are listening to.  
SIGNAL ERROR RATE: This option will display the level of  
signal errors in the current broadcast. The lower the number,  
the better the quality of the signal.  
BIT RATE: DAB allows broadcasters to vary the BIT RATE (or  
the amount by which an audio signal can be compressed)  
depending on the type of broadcast. This enables the amount  
of stations on a multiplex to be maximised. Speech and News  
are often broadcast at a lower Bit Rate; music needs a higher  
Bit Rate for good fidelity.  
TIME AND DATE:Time and date are updated by broadcasted  
information.

MORE DETAIL OF THE FM SETTINGS MENU OPTIONS  
SCAN SETTING: With this menu option you can set the  
scanning sensitivity of the FM radio to two different levels-  
‘Strong stations only’ or ‘All stations. Setting to ‘Strong

quicker scan. If you set to ‘All stations’ the scan will stop at  
every station detected, even if the signal is weak.  
FACTORY RESET: Select the ‘Yes’ sub-option to reset all the  
settings of your radio to factory original settings. The station  
list will also be cleared and any stored preset memories will  
be erased. After a factory reset the radio will re-scan the band

AUDIO SETTINGS: This option enables you to set the radio  
to receive FM in Auto mode (Mono/Stereo) or in Mono only.  
This may be useful if the signal is weak and the broadcast  
is noisy.  
SW VERSION: This option will display the version number of  
the control software currently installed in your radio. This will  
be helpful to a technician who is servicing the radio.
