Using the radio for the first time
1. Place your radio on a flat surface.
2. Fully extend the wire aerial located on the rear of your radio. Place
the wire antenna so that it is as straight as possible extending either
above or below the radio.
3. Insert the adaptor plug into the DC socket located on the rear of your
radio. Plug the adaptor into a standard 13 amp mains socket outlet.
The display will show 'WELCOME' for a few seconds. During this time
the radio is scanning to find a DAB radio signal. After a short time the
current time and day will appear on the display.
4. If no signal is found, '0:00' will be displayed. It may be necessary to
relocate your radio to a position giving better reception. You should
then carry out a scan to find stations as described on page 9.
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.
Characters appearing on the LCD display indicate that the radio is connected
to and powered from the mains supply.

Operating your radio
1. Press and release the On/Off button to switch on your radio.
When first switched on, the radio will be in DAB mode. After each use
the radio will remember the mode used and then switch on in that
mode the next time that it is used.
2. If the radio has been used before, the last used station will be selected.
3. If this is the first time that the radio has been used a scan of the Band
III DAB channels will be carried out (depending on whether scanning
was already completed in standby mode). During the scanning process
the display will show the progress of the station search. The number
on the right of the display is the number of stations that have been
found.
4. When the scan 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
during scanning will be played. The display will show the station name.
5. If no signals are found then it may be necessary to relocate your radio
to a position giving better reception. You should then carry out a scan
to find stations as described on page 9.
• Your radio has an indicator on the display to indicate the strength
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 control, the radio will remember the setting that you have applied
for the next time that it is used.
