Ready to Fly
To ensure the aircraft successful return to home after Failsafe activation, aim to only y in Ready to Fly mode.
The Phantom will automatically descend during the Failsafe process if there are less than 6 GPS satellites
detected for more than 20 seconds.
When the aircraft is landing automatically, users can control the aircraft’s position and altitude if the remote
controller signal is recovered.
Aircraft cannot navigate around vertical obstacles on its return home course during Failsafe. However, you can set
return home altitude value in Phantom Assistant to avoid hitting vertical obstacles through DJI Phantom Assistant.
Quickly ipping the S2 switch of the Remote Controller from top to bottom 5 times or more will reset the current
aircraft position as a new home point. Rear LED ight indicators will blink green rapidly when successful.

5 Low Battery Level Warning Function
If the DJI smart battery is depleted to a point that may affect the safe return of the aircraft, the low battery level warning
noties users to take action. Users are advised to land the aircraft immediately when they observe these warnings. The
thresholds for these warnings are automatically determined based on the current aircraft altitude and its distance from
the Home point. Details of the battery level warning are listed below:
