5.3 FIRMWARE UPDATE BY SD CARD
5.3.1 OVERVIEW
• An SD card is a precision device, so when you handle an SD card, respect the
following.
• When the power is turned ON, do not insert or remove a card.
• During installation, do not turn the power OFF.
• Since the card is manufactured to high precision, do not store it in a hot or humid
location, or in direct sunlight.
• Do not bend the card, scratch it, or give it a strong shock.
• Before downloading firmware to an SD card, check whether write-protection of the
SD card is canceled. If write-protection is enabled, an error code (error code 44,
etc.) will be displayed during download, and the download will fail.
• Before updating the firmware, disconnect the network cable and remove the wireless
board from this machine (so that they are not accessed during the update).
• If SC818 is generated during the software update, switch the power OFF -> ON, and
complete the update which was interrupted.
5.3.2 PREPARATION
• If the SD card is blank, copy the entire "romdata" folder onto the SD card.
• If the SD card already contains the "romdata" folder, copy the "M0D1 (machine code)"
folder onto the card.
• If the card already contains folders up to "M0D1 (machine code)", copy the necessary
firmware files (e.g. M0D1xxxx.fwu) into this folder.
Do not put multiple machine firmware programs on the same SD card. Copy the only model
firmware you want.
