Once you enable Boat Launch, these warnings will disappear.

Turn off Dynamic Home Point and then turn it back on. If the issue continues, fully close the app and reopen it.

Yes. When Boat Launch is enabled, the downward obstacle avoidance is automatically disabled to allow for automatic takeoff and landing. If you fly over land or other environments, make sure to check the status of downward obstacle avoidance to ensure safe operation.

1. It is recommended to use the rear of the vessel for takeoff and landing. Currently, DJI Matrice 400 supports takeoff from static vessels and landing on moving vessels with speeds below 10 knots.
2. Reserve a flat, unobstructed area of 3 m × 3 m on the deck for takeoff and landing. Ensure there is clear overhead space. Place the official landing point pattern in the center, making sure its size, color, and shape match DJI’s specifications. Do not attach any payloads to the underside of the aircraft.
3. During takeoff and landing, combine using the remote controller’s live video feed with direct visual observation to quickly notice any changes in the surrounding environment.
4. After the drone detects the landing point pattern, the remote controller will have sound and vibration alerts. You can press the C1 button to trigger auto landing.
5. During auto landing, when the drone is above the landing point pattern, continue to hold the throttle stick down to ensure a fast descent and reduce the risk of failed landing due to sudden changes in the environment.
6. During auto landing, the aircraft may automatically ascend due to failure in recognizing the landing point pattern, and exit landing mode if it rises above 20 meters. If the landing point pattern is successfully recognized during ascent, it will automatically re-enter landing mode.

This is normal. Remain stationary and wait for satellite signals to converge and obtain a stable position fix. This usually takes about 20 to 30 seconds, and may take longer if the signal is weak.

Power on the drone while holding it in your hands. After startup is complete, place the drone back on the vessel. The warning will disappear.
