(2) Execution method in the normal state
When proper operation of all signal items is confirmed, the
screen returns to the execution select screen and "O" is displayed
in the check item space.
(3) Execution method in the faulty state
If ERROR appears on the display, press [KNOB-8]", and
checking comes to an end. The screen returns to the execution
select screen and "X" is displayed in the check item space.
