Prescriptions
The CFX-750 display can use a prescription file to determine the rate of application in different areas
of the field.

types contain different information used by the display.
You must load a prescription from the USB drive to the internal memory of the CFX-750 display. The
display cannot read prescriptions directly from a USB drive.
