A 3.5mm Headphone socket is provided for use with headphones. Inserting
a plug automatically mutes the internal loudspeaker. Please be aware that
the sensitivity of headphones can vary widely. We therefore recommend
setting the volume to a low level before connecting headphones to the radio.
The headphone socket is compatible with stereo and mono headphones
but the audio will always be heard in mono.

1 Carefully, fully extend the telescopic aerial. Press the On/Off button to switch on the radio.

3 Rotate the Tuning control clockwise or anti-clockwise and then immediately give a long press on the Tuning
control for several seconds. Your radio will scan in an upwards direction (low frequency to high frequency) or in a
downwards direction (high frequency to low frequency) and stop automatically when it nds a station of sufcient
strength. 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 will display the station name.
4 When the waveband end is reached your radio will recommence tuning from the opposite waveband end.
5 Adjust the Volume. To switch off your radio press the On/Off button.
1 Rotate the Tuning control to tune to a station. The frequency will change in steps of 50kHz.
2 Adjust the Volume.
3 The Radio Data System (RDS) is a system in which inaudible digital information is transmitted
in addition to the normal FM radio programme.
4 Press Tuning as required to cycle through the various display options. The display options are
station name, scrolling text, program type, frequency, time or date.
Your radio will normally scan for FM broadcasts which are strong enough to give good reception. However, you may wish
the Auto-scan function to also be able to nd weaker signals, possibly from more distant radio transmitters.
1 When in FM mode, press Menu.
2 Rotate Tuning until 'SETTING' shows on the display. Press Tuning.
3 Rotate Tuning to switch between 'LOCAL' and 'DISTANT' options. The distant option will allow the radio to nd weaker
signals when scanning.
4 Press Tuning to conrm your selection. The Local or Distant setting is stored in the radio and remains in force until
changed or until a System Reset. Note: The initial setting (out of the box, or after a System Reset) causes the radio
to ignore weaker (or more distant) signals.
To recall a station preset
1 Press the On/Off button to switch on the radio.
2 Select the required waveband.
3 Press the required Preset button. Your radio will tune to the station stored in preset memory.
• The display will show 'EMPTY ' if no station has been stored to that preset.
You may store your preferred DAB and FM radio stations to the preset station memories. There are 6 memory presets in
your radio, 3 for DAB and 3 for FM. Presets are remembered by your radio in the event of a power failure. The procedure
is the same for both FM and DAB modes.
To store a station preset
1 Press the On/Off button to switch on the radio.
2 Select the desired waveband and tune to the required station.
3 Give a long press on the required Preset button until the display shows, for example, 'P1 SAVED'. Repeat this
procedure for the remaining presets as needed.
4 Stations which have been stored in preset memories may be over written by following the above procedure.

the spaces in the compartment. Take care to ensure all batteries are in-
serted with the correct polarity as shown inside the battery compartment.
Replace the battery cover. Reduced power, distortion and a ‘stuttering’
sound are all signs that the batteries may need replacing. If the radio is
not to be used for any extended period of time it is recommended that the
