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 LR14 (C 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.

We would recommend for economy that the RD-45 is used via the

AC adaptor whenever possible with battery operation for occasional
or stand-by use only.

IMPORTANT: The batteries should not be exposed to excessive heat

such as sunshine, fi re 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.

1

Using the AC adaptor

1. Insert the adaptor plug into the DC in socket on the rear of your
radio.

2. Plug the adaptor into a standard mains socket outlet. 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.

2. Press and release the On/Off button to switch on your radio. The On
indicator will light and the display will show 'Roberts Enjoy Listening'
for a few seconds.

3. If this is the fi rst time the radio is used a scan of the Band III DAB
channels will be carried out. If the radio has been used before the last
used station will be selected.

4. During the scanning process, the display will show 'Scanning' and as
each group of stations is detected the station count will be updated.
The bottom line of the display shows a bar graph indicating progress
of the scan.

5. 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 will be played. The display will show the station name in the
fi rst line of the display and other information in the second line.

6. If no signals are found it may be necessary to relocate your radio to
a position giving better reception. You should then carry out an auto
tune to fi nd stations as described on page 9 (see Finding new stations
on page 9).
