Notes:
• "Update Failed." is displayed at the bottom of the LCD screen when the updating
is not completed properly. "Failed" appears next to the failed item on the status
display. Even though an update fails, do not turn the power OFF until other
updates are finished. If "Update Failed" appears at the bottom of the screen, turn
OFF the power and then check the following items. After confirming and clearing
the problems, restart updating from the beginning.
- Does the USB device meet the conditions to be used for updating?
- Is the data file written properly on the USB device?
- Is the USB device installed properly?
- Do the USB device and equipment operate properly?
• The integrity check system is automatically operated before firmware updating.
During this operation, "Verifying Signature..." and "Progress: **%" are displayed
on the control panel. When the check is completed properly, no message for
notifying the success will appear and the firmware updating will start. If it fails,
"Invalid Signature" and "Copy Data with >valid signature in USB" will be shown.
In that case, firmware updating cannot be performed, so turn the power OFF and
disconnect the USB device. Check that there is no abnormality in the firmware
data, and reperform the update.
• When an system firmware (OS Data) update error or system software (HD Data)
update error occurs, "Update Failed" or "Failed" appears on the screen and the
error number appears next to the message.
