8.2 Firmware Updating with a USB Device
To update the firmware, store the update program and the firmware data files in a USB device.
The update program is "signatures.sig", and it needs to be stored in a USB device. It is necessary for
updating the firmware except that of the system firmware.
For the data file for each firmware, refer to the table of section 8.2.2Firmware type and data file name
for updating.
Notes:
Be sure to use the latest program when updating is performed.

files which have been changed from the base. This

data size is smaller than that for the standard package.
