"System" for the first update. After this is completed, do the "Opeation Panel"
update. (The screen goes off during the operation panel update. If a problem
occurs, you will not be aware of it.)
10. Press "Update" or press [#] on the 10-key pad.
Here is what happens on the screen:
The top bar tells you what the machine is doing ("Loading")
The middle bar shows the name of the module that the machine is presently
updating. (The example above shows that the machine is updating the
"Printer" module.)
The bottom bar is a progress bar. The '_' marks in the progress bar are
replaced by '' marks as uploading progresses.
When the update is completed, you will see the message "Update done."
Immediately below the message you will see the name of the SD card and
