First I would check the Field-IQ firmware version on your RSCM 75774-01. If it's v3.20 then you're all set. If not you would follow the "Upgrading the CFX-750 with Field-IQ" instructions here https://www.triangleag.com/cfx-750-support/ and during those steps you will also copy the latest Rate and Section Control firmware to the usb drive. Then it will re-apply your v7.79 CFX firmware and also update your Field-IQ module (RSCM 75774-01) firmware.
