Turn on or off the function through the [Invert] item on the touch screen.
Select ―Auto Invert‖ in the ―[Setup] (F10) → [System] → [Image]‖, thus the
spectrum can automatically invert when the color flow is steered to a certain angle
to accommodate operator’s habit of distinguishing flow direction.
Speed
This function is used to set the scanning speed of PW mode imaging.
Rotate the knob under [Speed] item on the touch screen.
There are 6 levels of scan speed available, the smaller the value the faster the
