Firmware Updating with USB Device

To update firmware, store update program and firmware data files in the USB device.
The update program is "signatures.sig", and it needs to be stored in the USB device. It is
necessary for updating firmware except that of the System firmware.
For the data file for each firmware, refer to the following tables.
Notes:
When performing the update, use the latest program.

Store the data file for updating in the model specific folder. This configuration is an example. The

Model specific folder name
Notes:
• Since the date and time set in the equipment are recorded in the firmware update log, make
sure that they are correct before updating the firmware.
• Never change the model specific folder name, since it is used for identifying the data file
when the data files used for updating multiple models are stored in the USB device.
