The Ground Station LED indicator is located below the bottom screen. The LED indicates the current state of the Ground Station battery. When charging, the Ground Station LED will blink Red, until the battery is fully charged. Once charged, the LED will stop blinking. During normal operation, the LED will be displayed in constant blue. When the Ground Station battery level has dropped to a point requiring an immediate recharge, the LED will turn to Red. It is not recommended to start a new flight with an amber indication on the LED.
