Battery operation

1. Remove the Battery cover on the rear of the unit by pushing the catch

downwards. Open the battery door.

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 on the rear of your radio. Close the battery door.

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-25 is used via the

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

Using the AC adaptor

Your radio is supplied with a Mains Adaptor.

1. Place your radio on a ﬂ at surface.

2. Insert the adaptor plug into the DC socket located on the left hand end of your radio.

3. Plug the adaptor into a standard 13 amp mains socket outlet. Whenever the adaptor is used, the batteries are automatically disconnected.

The AC adaptor should be disconnected from the mains supply and

the radio when not in use. The unit is only fully isolated from the mains if the AC adaptor is removed from the wall socket.

Operating your radio - DAB

1. Carefully extend the telescopic aerial.

2. Press the On/Off button to switch on your radio. The display will show "Welcome to Digital Radio" for a few seconds.

3. If this is the ﬁ rst time the radio is used a quick scan of UK Band III DAB channels will be carried out. The display will show "Now tuning". If the radio has been used before the last used station will be selected.

4. During Autotune, 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 bargraph indicating progress of the Autotune.

5. When the Autotune is completed the ﬁ rst station (in numeric-alpha

order 0...9...A....Z) will be selected.

6. If the station list is still empty after the Autotune your radio will display "No signal".

7. If no signals are found it may be necessary to relocate your radio to a position giving better reception.

Selecting a station - DAB

1. The top line of the display shows the name of the station currently selected.

2. Rotate the Tuning control to scroll through the list of available stations. Stop rotating the tuning control when you ﬁ nd the station that you wish to hear.

3. Press and release the Tuning control to select the station. The display may show "Now tuning" while your radio ﬁ nds the new station.

4. Adjust the Volume control to the required setting.

Note: If after selecting a station the display shows "Not Available" it

may be necessary to relocate your radio to a position giving better reception.

Secondary services - DAB

1. Certain radio stations have one or more secondary services associated with them. If a station has a secondary service associated with it the display will show ">" next to the station name on the station list. The secondary service will then appear immediately after the primary service when you rotate the tuning control clockwise.

2. Press and release the Tuning control to select the station.
