FIRMWARE UPDATE
After selecting "Update", three lines are displayed on the screen:
The first line tells you what is happening, the second line is the name of the
module, and the third line tells you about the progress of the operation. As the
update progresses, the underscores (_) in the progress bar are replaced by
asterisks.
The update is finished after all 10 underscores are replaced by asterisks.
NOTE: The progress bar (*****_ _ _ _) is not displayed for the operation panel
firmware after you touch "OpePanel". While the LCDC firmware is
updating, the power on key flashes on and off at 0.5 s intervals. When
the update is finished, the power key flashes on and off slower at 3 s
intervals.
When the update is finished, you will see a screen like the one below:
The first line prompts you that the update is finished, and the second line tells
you the name of the module that has just been updated.
NOTE: If you have selected more than one module for updating, only the
screen for the last module updated will be displayed.
