A USB cable is required. (A-B type, purchase separately) The firmware is updated through the USB port on the rear panel of the IC-9100.
The USB driver must be installed before connecting the USB cable between the IC-9100 and to the PC.
Save the setting data using the optional CS-9100 cloning software before starting the firmware update.
Please read "Firmware update instructions" (0.98MB) thoroughly and make sure what is required for the firmware update.
Never turn OFF the transceiver power or disconnect the USB cable while the update is being performed.
Never connect anything, not even a cable, to the REMOTE jack, otherwise the firmware update may fail.
If you connect two or more IC-9100s to the PC, turn the power ON for only the one that you want to update as the update tool works on only one transceiver at a time.
