Let's get started

Dynamic range control (DRC)

In DAB mode:
The dynamic range for each radio programme is set by the broadcaster for each radio
station and may be different for the types of programme broadcast, such as pop or
classical music or a chat show. The dynamic range control signal is transmitted in parallel
with the audio signal for each programme and with your radio you can use this control
signal to expand or compress the dynamic range (the difference between the loudest and
quietest sounds) of the reproduced audio signal. Changing the dynamic range can affect
the 'loudness' and/or 'quality of sound' of the programme that you hear so that it will be
more suited to your listening conditions and your own personal listening requirements.
e.g. in a noisy environment, where quiet sounds might be swamped, setting the
compression to maximum will 'boost' the quiet sounds, whilst keeping the loudest sounds
at their original level.
There are 3 levels of compression:
• DRC off - no compression. This is the default setting.
• DRC low - medium compression.
• DRC high - maximum compression.
1. Long press the Menu/Info button to enter the menu options.
2. Use the rotary Tune/Select control to scroll to DRC. Press to select.
Note: The current DRC setting will have an '*' in the display.
3. Use the rotary Tune/Select control to scroll through the options and press to select.

FM Radio mode

• Please make sure that the aerial is fully extended before you attempt to tune to an FM
station (a vertical position is recommended). This will ensure that the maximum signal
strength is available when the radio begins to scan. Extending the aerial also ensures
the best possible sound quality.
• If you are not already in FM mode, short press the Mode button until FM is highlighted,
then short press the rotary Tune/Select control (check the display).
