Using the clock radio for the fi rst time
1. Place your clock radio on a fl at surface.
2. Fully extend the wire aerial located on the rear of your clock radio.
Place the wire antenna so that it is as straight as possible extending
either above or below the radio.
3. Plug the mains lead into a standard 13 amp mains socket outlet. The
display will show 'ROBERTS' for a few seconds and will then show
'SET CLOCK'. During this time the radio is scanning to fi nd a DAB
radio signal. After a short time the current time and day will appear
on the display.
4. If no signal is found, 'NO CLOCK' will be displayed. It may be necessary
to relocate your clock radio to a position giving better reception. You
should then carry out a scan to fi nd stations as described on page 9.
IMPORTANT: The mains plug is used as the means of connecting the
clock radio to the mains supply. The mains socket used for the clock radio
must remain accessible during normal use. In order to disconnect the clock
radio from the mains completely, the mains plug should be removed from
the mains socket outlet completely.
Characters appearing on the LCD display indicate that the clock radio is
connected to and powered from the mains supply.

Operating your clock radio
1. Press the On / Standby button to switch on your clock radio.
When fi rst 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 clock radio has been used before, the last used station will be
selected.
3. If this is the fi rst time that the clock radio has been used a quick scan
of the Band III DAB channels may be carried out. (The scan is normally
performed automatically when the clock is fi rst set page 4). If new radio
stations are found, they will be added to the stored list of stations.
4. When the scan is completed the fi rst station (in numeric-alpha order
0...9, A...Z will be selected. The fi rst 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 'OFF AIR' will be displayed and it may
be necessary to relocate your clock radio to a position giving better
reception. You should then carry out a scan to fi nd stations as described
on page 9.
• Your clock radio has an indicator
on the display to indicate the
strength of the DAB radio signal being received.
Note: When fi rst 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
using the Volume Up or Down buttons, the radio will remember the setting
that you have applied for the next time that it is used.
