Emergency off [EMO] switch
Press the red emergency off [EMO] switch on the front of the system only if the
need to shut off the power arises due to emergency such as natural disaster, fire,
earthquake or personal injury.
The emergency off [EMO] switch is a large, red mushroom-shaped push button
labeled
with ‘EMO’ on it. The system comes to a halt if this button is pressed.
When press the emergency off [EMO] switch, the control power for this system is
shut off to bring the system to a stop. The main breaker of this system, however, is
