Using your EVOKE-1Elgar

This section provides information on using your EVOKE-1Elgar including tuning, selecting a station and altering the displayed information.

Switching on and off

Before switching on for the first time, check all connections, extend your aerial and ensure that the volume is low.

Push and release the Power button to switch the unit on or off. The LCD screen will light up when the unit is on.


Tuning the EVOKE-1Elgar is very simple. When you first switch on the unit it will start an automatic tuning process described below inTuning for the first time. You may want tore-tunethe unit at a later date if you move the unit to a different room or if you want to receive a newly introduced multiplex – seeRetuning your unit on page 8.

Tuning for the first time

When you switch on your EVOKE-1Elgar for the first time an autotune process will be performed automatically. A progress indicator on the display shows that autotune is underway.

If stations are found during the autotune

The stations will be stored in alphanumeric order. The first station on the list will be selected and you will hear it through the speaker. To listen to other stations, see Selecting a station on page 9.

If no stations are found during the autotune

‘No stations available’ will be shown on the display for a few seconds and then you see a menu of options.

Use the Tune knob to scroll through the following options and push it to select that option.

Tuning aid - See Tuning aid on page 12 for details of using the tuning aid to improve reception.

Autotune local - See Retuning your unit below for details of the local autotune option.

Autotune full - See Retuning your unit below for details of the full autotune option.


Retuning your unit

You can re-tuneyour unit at any time using the autotune process. You may wish to do this if a new multiplex is launched or you move your unit to another room. You do not need to perform an autotune to pick up new stations within a multiplex you are listening to as yourEVOKE-1Elgar monitors and refreshes the list of available stations automatically. The following two options are available:

Autotune local - scans all frequencies in the UK channel allocation. This should only take a few seconds.

Autotune full - scans the full range of digital frequencies in Band III. This may take a minute or more.

1.Ensure your EVOKE-1Elgar is switched on and the aerial is connected and fully extended.

2.Push and release the Autotune button once for local scan or hold down for around two seconds for a full scan. Note You can cancel Autotune by pushing the Autotune button again during the tuning process.

The display will indicate tuning is underway. When finished, the EVOKE-1Elgar will return to the station you were listening to and you will hear it through the speakers. All the stations found are now stored in the unit and you can select another station as described inSelecting a station on page 9.

If no stations are found, you see the message ‘No stations available’ and the display shows an option menu, see If no stations are found during the autotune on page 7 for details of this menu. Check your aerial is fully extended and try one of the available tuning options.

Adjusting the volume

Once you have tuned your EVOKE-1Elgar as explained above you can adjust the volume using the Vol knob.


Selecting a station

Once you have tuned your EVOKE-1Elgar you select the digital radio station you want to listen to using the Tune knob. If you have assigned stations to presets you can also select them directly by pressing the relevant numbered

button (1-6), see Storing and recalling presetson page 10.

1.The top line of the display shows the name of the currently selected station. Rotate the Tune knob to see the names of other stored stations on the bottom line of the display. Stop when you find the station to which you want to listen.

2.Push and release the Tune knob to listen to the station you have selected. The display may show ‘Now tuning...’ briefly as it finds the new station.

If a station has one or more secondary services available the display will show ‘>>’ next to the station name on the station list and they will appear after the primary service as you turn the Tune knob.

A secondary service will display ‘<<‘ before the station name on the station list indicating that it belongs to the primary service before it in the list. See page 14 for information on primary and secondary services.

If the station has ‘?’ before its name the service is currently inactive or invalid. If you select a station which has this symbol the EVOKE-1Elgar tries to tune to that station. If still unavailable ‘Station not available’ or ‘Stationoff-air’will be displayed andEVOKE-1Elgar will attempt to tune to an alternative station. A flashing cursor will indicate that this is underway. If you want to try to manually tune to this station you have five seconds after the message in which to push the Tune knob and the tuning aid will be displayed enabling you to adjust your aerial, see page 12 for details.

Resetting your EVOKE-1Elgar

A reset option is provided to enable you to reset your unit. This removes all presets, stored stations and favourite station settings and resets all options to defaults. Performing an autotune process will solve most problems but you may want to use this option if you move house or want to restore default values to options you have changed.

To select the reset option:

1.Press and hold the Setup button for more than two seconds. The display will show ‘Press Tune to confirm reset’

2.Press the Tune knob to confirm the reset or press no buttons for around seven seconds to cancel the reset.


Guide to digital radio

Your EVOKE-1Elgar enables you to receive and listen to DAB radio programmes. Digital Audio Broadcast (DAB) uses digital signals rather than traditional analogue signals enabling nearCD-qualityaudio with virtuallyinterference-freereception. DAB also enables broadcasters to transmit additional data along with the audio including other audio channels, text and in the future, perhaps computer data and images.

Digital radio is broadcast as groups of data called ensembles or multiplexes. Each multiplex can contain a number of stations (services) and each station contains a primary service and can contain secondary services as illustrated in the following diagram.

Each multiplex is transmitted in a set frequency range and received by your EVOKE-1Elgar for decoding. YourEVOKE-1

Elgar enables you to receive multiplexes broadcast in frequency band III (174-240MHz) and store the services in each multiplex for you to access. The number of multiplexes you receive will vary depending on your location. Band III

is divided into 41 channels identified as 5A to 13F. Each channel can contain one multiplex. Channels allocated to the UK are in the range 11B to 12D.

Multiplexes and stations have labels (names) which are used to identify them. Instead of needing to know a particular frequency to listen to your favourite broadcast you can simply select the station name. Secondary services and additional data such as text containing programme or multiplex information are also easily accessed using your EVOKE-1Elgar.

This section gives some of the most likely solutions to problems you might have with your EVOKE-1Elgar.

I can’t get any sound

Make sure your EVOKE-1Elgar is plugged in and switched on as explained on page 7. Check that the volume is not set too low, see page 8 for details.

Ensure that you have completed the Autotune procedure to find digital radio stations as explained on page 7.

Display says ‘No stations available’

Check that your aerial is connected and fully extended. Use the Autotune facility to search for services, see page 7. Try using the tuning aid to adjust your aerial or radio position, see page 12.

I can’t access secondary services

At the time of publishing not many secondary services are available. If secondary services are available for the currently selected station the secondary ‘>>’ indicator will be shown on the display next to the station name, see page 9.

Display says ‘Station off-air’

This may occur if a broadcaster takes a station off-airwhilst you are listening to it. If your radio is tuned to a secondary serviceEVOKE-1Elgarre-tunesto the associated primary service. If tuned to a primary service,EVOKE-1Elgar will wait until the service resumes or you can choose a new station.

I can’t hear the station I have selected on the display

The top line of the display shows the currently selected station. To change station you need to scroll the station list displayed on the bottom line of the display and confirm your selection by pressing the Tune knob, as described on page 9.

I hear a ‘burbling’ sound on some stations

Although DAB is excellent at providing quality audio from very little signal, the quality can suffer if the signal strength is too low. If that happens, a ‘burbling’ sound can sometimes be heard.

To help reduce this, check that your aerial is fully extended and upright. If the problem persists try moving your EVOKE-1Elgar or repositioning your aerial using the tuning aid described on page 12. See page 17 for additional advice on aerials.

For the latest troubleshooting information visit the support section on our website at


Aerial advice

Your EVOKE-1Elgar is supplied with a telescopic DAB aerial. This is an indoor aerial which is designed to give good reception in areas with good to moderate DAB signal strength. In areas with poor DAB coverage or poor signal strength you may want to consider using a loft mounted or external aerial. To find out about coverage in your area contact one of the organisations listed on page 15.

The following options may help you improve reception in your area. A range of DAB aerials are available from our website, see page 18.

1.Telescopic Aerial Optimise the position of your telescopic aerial by extending it as high as possible and pointing it vertically. Use the tuning aid to fine tune the aerial placement, see page 12.

2.TV/FM Aerial If you have an externally mounted TV or FM aerial it may provide a stronger signal than an indoor aerial but as they are not tuned for the digital radio frequency range and are pointed at your local TV/FM transmitter, reception may be no better. The standard TV or FM RF connector cannot be plugged into your EVOKE-1Elgar directly, you will need to use an RF toF-typeadapter. You may also find that you need to use a signal booster if you want to use the aerial for both TV or FM and DAB reception.

3.External or loft mounted DAB Aerial Two main types are used. These types of aerials may require professional


Dipole – for use in marginal signal areas, this type is omnidirectional and should increase the strength of all DAB stations being received.

4-elementaerial – for use in marginal or poor signal areas, this type is directional and has high gain. Like a TV or FM aerial this type needs to point at the transmitter. Installation requires someone to move the aerial while you use the tuning aid. If you receive signals from multiple transmitters you should point your aerial at the one which gives the best signal for the services to which you want to listen.

4.Signal booster This is a signal amplifier which connects into an aerial cable and boosts the strength of the received signal. If your aerial provides marginal reception, even after adjusting its position, a booster may improve your reception.
