Pioneer DEH-P544R Illumination Colour

Hi,

I've just dragged the above head unit out of a cupboard to replace the
standard fit radio/CD in my Fabia. It's working fine, but I'm sure I
remember that the illumination clour is switchable. I've lost the
manual, so I got a dowlnloaded scanned manual from some dodgy website,
but it doesn't mention it anywhere. Can anyone confirm or deny it, and
if it is switchable, how? It's not in the setup menu.
