4.8 LED lighting check .....
(08) LED
(1) Outline
The LED on the panel is checked visually for proper lighting
by making the segments light from the upper left to the lower
right one after another and then making them flash by area.
08:LED
Lighting sequence: All LED segments from the upper left to the
lower right on the panel
Double color LED should light in the following order.
Green: ON, Red: OFF -> Green: OFF, Red: ON -> Green:
ON, Red: ON (orange)
(2) Execution method in the normal state
After confirming visually that all LED segments light properly,
press [KNOB-8], and the screen returns to the execution select
screen and "O" is displayed in the check item space.
