LEDS: AC NORMAL: Green when commercial voltage is in range and present, provided
battery circuit breaker is closed; off otherwise.
BATTERY IN USE: Red while unit is running in Inverter mode. In AC mode,
blinks when batteries are low or DC circuit breaker is off.
OUTPUT LOAD: Functions in AC mode only, providing an indication of the
actual output load. Each green LED represents 1/9 of total available output of
each unit. The red LED signifies overload.
BATTERY STATUS: Functions in Inverter mode only, providing a measure of
battery time remaining. As battery begins to run down, LEDs extinguish from left
to right. At low battery warning, only the two red LEDs are still on.

Alarm frequency changes at low battery warning to two per second.
