Operation
POWER ON/STANDBY SWITCH. Pressing the top portion of the switch turns
power on; pressing the bottom portion of the switch places the unit in the
STANDBY mode.
When power is turned on, the unit goes through the power up cycle. This cycle
may last between 30 seconds and five minutes, depending on the amount of
software that needs to be loaded and conditioned. The Elgar logo will be
displayed during the power up cycle.
NOTE: To prevent large inrush currents flowing while resetting the SW, allow
several seconds before cycling power, especially if power is cycled via an
external circuit breaker.
