Smart RTH
Use the RTH button on the remote controller or tap the RTH button in the DJI GO 4 app and follow the on-
screen instructions when GPS is available to initiate Smart RTH. The aircraft will then automatically return
to the last recorded Home Point. Use the remote controller to control the aircraft's speed or altitude to
avoid a collision during the Smart RTH process. As the aircraft returns, it will use the primary camera to
identify obstacles as far as 300m in front, allowing it to plan a safe route home. Press and hold the Smart
RTH button once to start the process, and press the Smart RTH button again to terminate the procedure
and regain full control of the aircraft.
Low Battery RTH
The low battery level failsafe is triggered when the DJI Intelligent Flight Battery is depleted to a point that
may affect the safe return of the aircraft. Users are advised to return home or land the aircraft immediately
when prompted. The DJI GO 4 app will display a notice when a low battery warning is triggered. The
aircraft will automatically return to the Home Point if no action is taken after a ten-second countdown. The
user can cancel the RTH procedure by pressing the RTH button on the remote controller. The thresholds
for these warnings are automatically determined based on the aircraft's current altitude and distance from
the Home Point.
The aircraft will land automatically if the current battery level can only support the aircraft long enough
to descend from its current altitude. The user can still use the remote controller to alter the aircraft's
orientation during the landing process.
The Battery Level Indicator is displayed in the DJI GO 4 app, and is described below:
