1. Steady light indicating main power is ON and
the battery is charged
2. Flashing slowly (lights every second) indicates no main
power but the battery is charged.
3. Flashing quickly (lights every 1/4 of a second)
indicates main power on but discharged battery
4. Light OFF indicates no main power and discharged
battery.
