How to change radio from lo to dx?

[ukmobileman]

lo/dx selection as in the citroen radio guide
LO
Indicates that station searching will be for transmitters with the strongest signals. If no strong signal is found after a complete sweep in LO , the next sweep will automatically be in DX . Returns automatically to LO 8 seconds after last using the tuning rocker switch.
DX
Indicates that station searching will include transmitters with weak signals.
that's all there is, seems it's automatic selected if needed, when you scan for radio signals .

If you press the search up/down button, and then again, it will also go into DX mode.
