When Critical battery level warning is triggered and the aircraft begins to land automatically,
you may push the throttle upward to make the aircraft hover at its current altitude, giving you an
opportunity to navigate to a more appropriate landing location.
The colored zones and markers on the battery level indicator bar reflect the estimated
remaining ight time. They are automatically adjusted according to the aircraft’s current location
and status.

The aircraft cannot avoid obstruction during the Failsafe RTH when
theObstacle Sensing System is disabled. Therefore, it is important to set
an suitable Failsafe altitude before each ight. Launch the DJI GO app
and enter “Camera” and select “MODE > Advanced Settings > Failsafe
mode” to set the Failsafe altitude.

If the aircraft is ying under 20 meters (65 feet) and Failsafe (including
Smart RTH, Lower Battery RTH ) is triggered, the aircraft will first
automatically ascend to 20 meters (65 feet) from the current altitude.
You can only cancel the ascending by exiting the Failsafe. Refer to “RTH
Button” on page 33 for more information on how to exit the Failsafe and
regain the control of the remote controller.

Aircraft automatically descends and lands if RTH is triggered when the
aircraft ies within a 20 meters (65 feet) radius of the Home Point. Aircraft
will stop ascending and immediately return to the Home Point if you move
the throttle stick if the aircraft reaches 20 meters (65 feet) altitudes or
beyond during Failsafe.

if you move the throttle stick after the aircraft rises above 65 feet
(20m) but below the pre-set Failsafe RTH altitude, the aircraft will stop
ascending and immediately return to the Home Point.
