    Improvement

    The firmware update modifies the IC-9100's transmitted DTCS code modulation waveform so undesired sound is not heard at the receiver.

    A USB cable is required. (A-B type, purchase separately)

    The firmware is u​pdated through the USB port on the rear panel of the IC-9100.

    You must install the USB driver before connecting the USB cable between the IC-9100 and the PC. Download the USB driver here .

    Save the setting data using the optional CS-9100 cloning software before starting the firmware update.

    Thoroughly read "Firmware update instructions (here)" t​o know what the update requires.

    Never turn OFF the transceiver power or disconnect the USB cable during the update.

    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.

    Improvements

    Fixed an audio problem when switching the band while receiving in the FM mode.

    F​ixed a DTCS and tone squelch decoding problem when receiving in the 9600bps mode.

    Fixed a improper S-meter indication problem when the mode is changed while receiving.

    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 ins​tructions" (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.
