To update the firmware
- An SD card or an SDHC card is required.
- Format the card in the IC-7300 before using it for the update. (First, save any data that is on the card, if necessary.)
- Unzip and save the downloaded firmware file in “IC-7300” folder that is on the card.
- Save the transceiver’s data onto a separate card before doing the update. It is possible that your data could get lost or corrupted during the update. Thoroughly read Section 8 (USING AN SD CARD) of the “FULL MANUAL” for details.
- Thoroughly read Section 15 (UPDATING THE FIRMWARE) of the “FULL MANUAL” before starting the update.
- Never turn OFF the transceiver power during the update.
- The firmware will be updated to the following versions.
