Using the radio for the ﬁ rst time

1. Place your radio on a ﬂ at 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 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, '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 ﬁ nd 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 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 radio has been used before, the last used station will be selected.

3. If this is the ﬁ rst 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 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 it may be necessary to relocate your radio to a position giving better reception. You should then carry out a scan to ﬁ nd 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 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 control, the radio will remember the setting that you have applied for the next time that it is used.

If you need any further advice, please call our Technical Helpline on :-

Selecting a station - DAB

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 then the secondary service will then appear immediately after the primary service as you rotate the Tuning control.

Manual tuning - DAB

Manual tuning allows you to tune your radio to a particular DAB frequency in Band III. Any new stations found will be added to the station list. This function can also be used to assist the positioning of the aerial or the radio to optimise reception for a speciﬁ c channel or frequency. Note that UK DAB stations are located in the range of channels 11B to 12D.

1. Press and release the Menu button. The DAB menu will show on the display.

2. Rotate the Tuning control until the display shows 'MANUAL'. Press and release the Tuning control to enter the manual tune mode.

3. Rotate the Tuning control to select the desired DAB channel.

4. Press and release the Tuning control to tune to the chosen frequency.

5. If a signal is present, this will be indicated on a signal strength display. The minimum signal marker (

) shows the minimum signal strength needed for good DAB reception. The signal indicator chevrons go up or down showing the changing signal strength as you adjust the wire aerial or your radio position. Press and release the Tuning control again to return to the normal DAB tuning mode.

Dynamic Range Control (DRC) - DAB

The DRC facility can make quieter sounds easier to hear when your radio is used in a noisy environment.

There are three levels of compression:

DRC 0 No compression applied. (default)

DRC 1/2 Medium compression applied.

DRC 1 Maximum compression applied.

1. Press and release the On/Off button to switch on your radio.

2. Repeatedly, press and release the Mode button until the DAB mode is selected.

3. Press and release the Menu button. The DAB menu will show on the display.

4. Rotate the Tuning control until 'DRC' appears on the display. Press and release the Tuning control. The display will show the current DRC value.

5. Rotate the Tuning control to select the required DRC setting (default is 0).

6. Press and release the Tuning control to conﬁ rm the setting. After several seconds the display will return to the normal radio display.

Note: Not all DAB broadcasts are able to use the DRC function. If the broadcast does not support DRC, then the DRC setting in the radio will have no effect.

Prune stations - DAB

Over time, some DAB services may stop broadcasting, or may change location and then not be able to receive a station. In order to remove such stations from the DAB station list, the Prune stations function will delete the DAB stations from your station list that can no longer be received.

Stations which cannot be found or which have not been received for a very long time are shown in the station list with a question mark.

1. Press and release the On/Off button to switch on your radio.

2. Repeatedly, press and release the Mode button until the DAB mode is selected.

3. Press and release the Menu button. The DAB menu will show on the display.

4. Rotate the Tuning control until 'PRUNE' appears on the display. Press and release the Tuning control.

5. Rotate the Tuning control to select 'Y'. Press and release the Tuning control to cause the stations list to be pruned, eliminating unavailable stations.

6. If you do not wish to prune stations select 'N' in step 5 and then press and release the Tuning control. The display will revert back to the previous display.

Note: If you have moved to a different part of the country you should

also carry out a search for new stations (please see the section 'Finding new stations' on page 9).

Operating your radio - FM auto-tune

1. 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.

2. Press and release the On/Off button to switch on your radio.

3. Repeatedly, press and release the Mode button until the FM mode is selected.

4. Rotate the Tuning control clockwise and then press and hold down the Tuning control for 2 - 3 seconds. This will cause your radio to search from low frequency to high frequency and to stop automatically when it ﬁ nds a station of sufﬁ cient strength.

5. After a few seconds the display will update. The display will show the frequency of the signal found. If the signal is strong enough and there is RDS data present then the radio may display the station name.

6. To ﬁ nd other stations press and hold the Tuning control as before.

7. Rotate the Tuning control anti-clockwise and then press and hold down the Tuning control for 2 - 3 seconds. This will cause your radio to search from high frequency to low frequency and to stop automatically when it ﬁ nds a station of sufﬁ cient strength.

8. When the end of the waveband is reached your radio will recommence tuning from the opposite end of the waveband.

9. Adjust the Volume to the required setting. To switch off your radio, press and release the On/Off button.

Note: If you ﬁ nd that FM reception is poor, try repositioning the wire aerial. Place the wire antenna so that it is as straight as possible extending either above or below the radio for optimum reception.

If you ﬁ nd that an FM broadcast has a lot of background hiss, this may often be reduced by setting the radio into Mono reception mode for the current FM station. Please refer to the section 'Stereo / Mono setting - FM' on page 17 for further details.
