Frequently Asked Questions
What is the ingress protection (IP) rating of DJI Matrice 400? Can I fly the drone in the rain?
It is IP55 rated. Do not fly in rain heavier than 100 mm / 24 h.
The IP rating is not permanently effective and may decrease due to product wear and tear.
What does the sensing system of DJI Matrice 400 consist of?
Omnidirectional binocular vision system
Downward-facing binocular vision system
LiDAR (horizontal rotating + upward)
Downward 3-D infrared range sensor
Six-directional mmWave radar
How is the obstacle-avoidance capability of DJI Matrice 400?
Power-line sensing:
Facing a main line (21.6 mm steel-core wire) — obstacle sensing supported up to 25 m/s.
Facing both main (21.6 mm) and distribution (12 mm) lines — obstacle sensing supported up to 17 m/s.
Performance varies with clouds, fog, rain, snow, object material, and shape. The aircraft cannot actively avoid fast-moving objects; fly with caution. The mmWave radar function is unavailable in some countries/regions.
How is the payload capacity of DJI Matrice 400?
The third gimbal connector supports up to 6 kg. When using the single downward gimbal, dual downward gimbals, and third connector together, the combined weight of non-DJI payloads must not exceed 6 kg. Contact the payload manufacturer for a test report to ensure safe flight under low-battery conditions.

Why are the front and rear propellers positioned at different heights?
To improve propulsion efficiency and flight stability.
Can I replace the propellers myself?
Yes, but only in emergencies. After the mission, have your dealer verify proper installation.
What should I note when taking off and landing on a vessel?
1 Reserve a 3 m × 3 m flat deck area with clear overhead space and official landing-pattern marker.
2 Supports takeoff from static vessels and landings on vessels moving < 10 knots.
3 During auto-landing the aircraft may ascend if the pattern is lost; it re-enters landing when the pattern is reacquired.
4 Press C2 anytime to switch to manual mode.
5 Do not attach payloads to the aircraft underside.
Any precautions when using the top-mounted rotating LiDAR?
1 Always install the protective cover when not in use.
2 If the dome gets dirty, clean it with the supplied cloth for optimal performance.
Does DJI Matrice 400 support relay functionality? How many aircraft can be relayed at once?
Yes. One M400 can act as an onboard relay for one additional M400.
Feature unavailable where 5 GHz is disallowed; follow local regulations.
