That appears to correctly select upper or lower sideband for ssb reception, but doesn't seem to affect the macro tuning behaviour. This is what I would expect from the help - I understand that the red lines define the offset from the tuning frequency of a "digital oscillator" used for demodulating ssb and cw signals.

You have to set vertial red lines to another side.
