Follow instructions on page 2.
Some steps may not apply to the Club car ERIC charger, as there is no button or screen on the club car version, but the inner workings are the same as the IC650. To verify proper download of the charge profile after update, insert a blank USB drive into the charger and use the Delta-Q IDAT software to check the charge profile and any stored charge data.
