If you wish to completely reset your radio to its initial state perform a factory reset.
Apply a long press on Info/Menu. Choose ‘SYSTEM’, ‘FACTORY’ then ‘RESET’.
All user entered settings will be erased.
Apply a long press on Info/Menu. Choose ‘SYSTEM’, ‘LANGUAGE’ then choose
your desired language from the list.
The software version display is only for reference. Apply a long press on Info/
Menu. Choose ‘SYSTEM’ and then ‘SW version’.
Your radio has 2 alarms which can be set to wake you by DAB, FM radio or buzzer. Each alarm can be set to sound, once, daily on weekdays or at weekends.
Note: The alarms can only be set with the radio in standby mode. Alarms may be used whether the radio is powered from the mains or the batteries. Alarms will be
retained in the event of a power failure. If no buttons are pressed for 1 minute, your radio will exit the alarm setup.
1 When in standby mode, apply a long press on Alarm 1 or Alarm 2 button. Press Tuning.
2 Rotate Tuning to select ON or OFF. If OFF is selected any current setting for that alarm will be cancelled.
3 With 'ON' selected, press Tuning.
4 Choose the desired alarm hour then the minute.
5 Choose the desired alarm day option: ONCE, WEEKDAYS, WEEKENDS or DAILY.
• If setting the alarm to once only, choose the alarm day, month and year.
6 Choose the desired alarm source (DAB, FM, BUZZER).
If setting the alarms to the radio option, choose ‘LAST’ to wake up to the last listened radio station or choose a
preset station which has been stored.
Note: That you can only use a preset which has already been stored.
7 Choose the desired alarm volume using the Tuning control. The radio uses the saved volume settings for each
radio alarm when it sounds.
8 Press Tuning to conrm the alarm settings. ‘SAVED’ will show on the display before exiting the alarm setup.
Radio alarms are indicated by the symbol and the alarm number. Buzzer alarms are indicated by the symbol
and the alarm number.
The alarm will sound at the selected times for up to 60 minutes unless cancelled. The maximum volume used for the
alarm will be specied during alarm setup. When your radio is set to wake by the radio alarm, your radio will switch
to the selected radio station. If the radio cannot tune to the specied radio station, the buzzer will be used instead.
Note: If the radio is switched on because of a radio alarm you can control basic functions such as the volume.
When the buzzer alarm activates it will start softly and gradually increase in level. The alarm icon will ash on the screen
and the radio will automatically switch back to standby mode when the 60 minutes have elapsed.
Apply a long press on Info / Menu to access the following DAB menu options.
Manual tune - Choose ‘MANUAL’ and then the desired DAB channel. The
minimum signal marker ( ) shows the minimum strength needed.
DRC - Choose ‘DRC’ then choose ‘0’, ‘1/2’ or ‘1’. The DRC facility can make
quieter sounds easier to hear when your radio is used in a noisy environment.
Note: Not all DAB broadcasts use the DRC function.
Prune station - Choose ‘PRUNE’ and then ‘PRUNE ?’ to remove any stations
that are no longer available.
Apply a long press on Info / Menu to access the following FM menu options.
Scan setting - Choose ‘SETTING’ and then either ‘DISTANT’ (your radio will
scan for both weak and strong signals) or ‘LOCAL’ (your radio will scan for
stations with good reception).
Stereo / Mono setting - Your radio will play stereo broadcasts in stereo (via
headphones) so long as the received signal is of adequate strength. However,
as a stereo signal becomes weaker the audio signal will become poorer.
To reduce any hiss press Tuning. The display shows ‘MONO’. To return to
stereo/mono mode press Tuning, the display shows ‘AUTO’.
1 Remove the battery cover located underneath
the unit by applying pressure to the catch in the
direction shown by the arrow and then lifting off
the cover.
2 Insert four C size (LR14) 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. 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 recommend for economy that the radio is used via the AC adaptor
whenever possible with battery operation for occasional use only.
If long term battery powered use is required, we recommend using the Eco
power saving mode. This mode will maximise battery life if the radio is only
used occasionally and if it is not connected to the mains at other times.
