Does a load need to be attached to change the profile on the M4 cord?

You can make the change with no load attached, place your finger on the profile selector, the LED light will rotate between green and yellow. When the profile light you want is showing (ie yellow LED) remove your finger from the profile selector button. The LED light will return to flashing green showing it is ready to accept a load. When you attach the load the LED light will be solid yellow and the diesel profile will be in place.
