  • Connect the F9P receiver to your PC via USB
  • Open u-center
  • Connect the receiver (button at the top left) to the correct COM port

• Verify that the receiver is correctly connected

• Click Tools > Firmware update...

  • Select the previously downloaded .bin file in Firmware image
  • Check Use this baudrate for update and select 9600
  • Uncheck the other four options (Enter safeboot, ...)

• Click GO (bottom left of the window)

• Wait for the update procedure to finish

Finally
