Introduction  
UNPACKING  
DAB (Digital Audio Broadcasting) technology allows many  
more radio stations compared to FM. DAB transmissions do  
away with problems of hiss and fade that plague AM and  
FM broadcasts and are less likely to be affected by adverse  
weather conditions or other sources of interference. In  
addition to speech and music DAB transmissions carry high  
levels of data - far greater than the limited RDS information  
available on FM stations.  
Unlike FM, DAB is broadcast on many frequencies. Many  
countries in Europe, including the UK use Band III (174-230  
MHz); others, France for example, use the L-Band (1452-  
1492 MHz). Germany uses both bands.  
Your radio can tune Band III. Countries in Europe that use  
Band III include: Belgium, Denmark, Holland, Italy, Norway,  
Portugal, Spain, Sweden, Switzerland. Your radio will tune  
stations in all these countries.  
Your radio cannot receive French or German stations  
broadcasting in the L-Band though FM services are available  
all over Europe.  
Carefully unpack the unit. If it is damaged, please return it to  
your nearest Tesco store for replacement. Remember to take  
your purchase receipt with you.  
Retain the User Handbook. If you pass the unit on to a third  
party make sure you pass on the handbook.

CONTENTS  
The carton should contain:  
The DAB-109CRF DAB Digital radio alarm clock  
Operating Manual  
If any items are missing or damaged, contact your nearest  
TESCO store for a replacement. Have your receipt ready when  
you call. Retain the packaging. If you dispose of it, do so  
having regard to any recycling regulations in your area.  
LOCATION  
Place the unit on dry stable surface away from heat and  
damp and where it is unlikely to fall or be knocked over.  
Being digital, DAB transmissions can have a wider frequency  
range and greater dynamics than that available with FM  
technology.  
FM reception is available on the DAB-109 for use in those  
locations where there is no usable DAB service.  
A headphone output is provided for personal listening.

mode.  
‘Station list’ appears on the display.  
Press the STANDBY/ON button.  
The radio scans all usable stations (full scan) and stores them  
alphanumerically - 1 Radio, 2 Radio, AA Radio, AB Radio...  
The initial scan will take a few minutes. After the scan, the  
number of stations found will be displayed, the clock will be  
set, the radio will display the first station in the sequence and  
begin playing at the default system volume of 10.  
Note: If no stations are found after the scan,‘0 Services Found,  
then ‘Service N/A’ will be displayed. If this happens, switch  
the radio off and move it to a location with a stronger signal.

or down the band and search for a station.  
RDS STATION NAME AND RADIOTEXT  
RDS is a secondary digital information channel that is  
broadcast with many FM radio programs. The RDS channel  
will often include the name of the station and can also  
include Radiotext. Radiotext may contain information about  
the program, artist or presenter currently on-air.  
When RDS is available from the station tuned, the station  
name will be displayed (in place of the station frequency)  
and Radiotext will scroll across the display (if broadcast).  
Press the PRESETS button briefly.  
Turn the VOLUME/SELECT control to find the preset  
number you want.  
As the knob is turned, the display will show the station stored  
in each preset number.
