NOTICE: All of the situations listed above indicate normal system operation; no action is required.
However, if the BBU pump is running or has run, check the primary pump and actively monitor the
charger status for battery life. Always reset the charger after the pump runs.
During normal system operation, the 'SYSTEM ALERT' LED blinks while the oat switch is on,
indicating the pump should start within 3 seconds. The "AC POWER" LED is lighted
(solid or blinking) as long as the system is plugged in to an operating AC power circuit.
