Battery operation
1. Remove the battery cover on the back of the unit by sliding the cover
in the direction of the arrow.
2. Insert six LR6 (AA size) batteries into the spaces in the compartment.
Take care to ensure all batteries are inserted with the correct polarity
as shown next to the battery compartment. Replace the battery cover.
3. Reduced power, distortion and a ‘stuttering’ sound are all signs that
the batteries may need replacing.
4. If the radio is not to be used for any extended period of time it is
recommended that the batteries are removed from the radio.
1
We would recommend for economy that the radio is used via the AC
adaptor whenever possible with battery operation for occasional use
only.
IMPORTANT: The batteries should not be exposed to excessive heat
such as sunshine, fire or the like. After use, disposable batteries should
if possible be taken to a suitable recycling centre. On no account
should batteries be disposed of by incineration.
If you need any further advice, please call our Technical Helpline on :020 8758 0338 (Mon-Fri)

Using the AC adaptor
1. Place your radio on a flat surface and plug the mains adaptor into the
DC input socket located on the left hand side of your radio (marked
'DC') ensuring that the plug is pushed fully into the socket.
2. Plug the other end of the mains adaptor into a standard 13A mains
socket outlet and switch on the wall socket. Whenever the adaptor is
used the batteries are automatically disconnected.
The AC adaptor should be disconnected from the mains supply and
from the radio when not in use.
IMPORTANT: The mains adaptor is used as the means of connecting the
radio to the mains supply. The mains socket used for the radio must remain
accessible during normal use. In order to disconnect the radio from the
mains completely, the mains adaptor should be removed from the mains
socket outlet completely.

Operating your radio - DAB
1. Carefully extend the telescopic aerial. The aerial should be fully
extended and positioned vertically for optimum reception.
2. Press the On/Standby button to switch on your radio, the display will
show 'WELCOME' for a few seconds. After each use the radio will
remember the mode used and then switch on in that mode the next
time that it is used.

3. If this is the first time the radio is used a scan of the Band III DAB
channels will be carried out. This is known as 'Auto tune'. If the radio
has been used before the last used station will be selected.
4. During Auto tune each group of stations will be detected and the station
count will be updated.
5. When the Auto tune is completed the first station (in numeric-alpha
order 0...9...A....Z) will be selected. The first station in the list of stations
found will be played.
6. If no stations are found then 'OFF AIR' will be displayed and it may be
necessary to relocate your radio to a position giving better reception.
You should then carry out an auto tune to find stations as described
on page 9 (see Finding new stations on page 9).
•
on the display to indicate the strength
Your radio has an indicator
of the DAB radio signal being received.
Note: When first switched on, the radio will set the volume to a moderately
high level, in case the broadcast is very quiet. After you have set the
volume, the radio will remember the setting that you have applied for the
next time that it is used.
