•
Pay attention to the flight environment. The Downward Vision System and Infrared
Sensing System only work under limited conditions and cannot replace human control
and judgment. During flight, always pay attention to the surrounding environment and
to the warnings on DJI Fly and be responsible for and maintain control of the aircraft.
•
The aircraft has a max hovering altitude of 5 m if GNSS is unavailable.
•
The Downward Vision System may not function properly when the aircraft is flying
over water. Therefore, the aircraft may not be able to actively avoid water below when
landing. It is recommended to maintain flight control at all times, make reasonable
judgments based on the surrounding environment, and avoid relying on the
Downward Vision System.
•
Note that the Downward Vision System and Infrared Sensing System may not function
properly when the aircraft is flying too fast. The Infrared Sensing System only takes
effect when the flight speed is no more than 12 m/s.
•
The Downward Vision System cannot work properly over surfaces that do not have
clear pattern variations or there is weak light. The Downward Vision System cannot
work properly in any of the following situations. Operate the aircraft cautiously.
a) Flying over monochrome surfaces (e.g., pure black, pure white, pure green).
b) Flying over highly reflective surfaces.
c) Flying over water or transparent surfaces.
d) Flying over moving surfaces or objects.
e) Flying in an area where the lighting changes frequently or drastically.
f) Flying over extremely dark (< 10 lux) or bright (> 40,000 lux) surfaces.
g) Flying over surfaces that strongly reflect or absorb infrared waves (e.g., mirrors).
h) Flying over surfaces without clear patterns or texture. (e.g., power pole).
i) Flying over surfaces with repeating identical patterns or textures (e.g., tiles with
the same design).
j) Flying over obstacles with small surface areas (e.g., tree branches).
•
Keep the sensors clean at all times. DO NOT tamper with the sensors. DO NOT use the
aircraft in environment with dust and humidity. DO NOT obstruct the Infrared Sensing
System.
•
DO NOT fly when it is rainy, smoggy, or if there is no clear sight.
•
Check the following every time before takeoff:
a) Make sure there are no stickers or any other obstructions over the Infrared
Sensing System or Downward Vision System.
b) If there is any dirt, dust, or water on the Infrared Sensing System or Downward
Vision System, clean with a soft cloth. DO NOT use any cleanser that contains
alcohol.
c) Contact DJI Support if there is any damage to the glass of the Infrared Sensing
System or Downward Vision System.
