Gday Nev,my manual says to turn clock mode on;
Turn audio off
push preset button 4 while pushing mode/tune button for more than 6 seconds.
To change display priority;
push preset button 4 while pushing disp button for more than 6 seconds.
I haven't tried this on mine so if anything blows up it's not my fault.It is in the manual.
Cheers.
