Power Supply
The controls and indicators function as follows:
Power switch—The Power switch is used to turn system power
on and off. The off position is indicated by a 0; the on position is
indicated by a 1.
The Power switch also functions as the system circuit breaker.
In the event of a power surge, the breaker will trip, causing the
Power switch to return to the off position (0). Turning the system
on resets the circuit breaker. If the circuit breaker trips, wait one
minute before turning the system back on.
