• The vision systems cannot accurately identify large structures with frames and cables,
such as tower cranes, high-voltage transmission towers, high-voltage transmission lines,
cable-stayed bridges, and suspension bridges.
• The vision systems cannot work properly near surfaces without clear pattern variations
or where the light is too weak or too strong. The vision systems cannot work properly in
the following situations:
a. Flying near monochrome surfaces (e.g., pure black, white, red, or green).
b. Flying near highly reflective surfaces.
c. Flying near water or transparent surfaces.
d. Flying near moving surfaces or objects.
e. Flying in an area with frequent and drastic lighting changes.
f. Flying near extremely dark (< 10 lux) or bright (> 40,000 lux) surfaces.
g. Flying near surfaces that strongly reflect or absorb infrared waves (e.g., mirrors).
h. Flying near surfaces without clear patterns or textures.
i. Flying near surfaces with repeating identical patterns or textures (e.g., tiles with the
same design).
j. Flying near obstacles with small surface areas (e.g., tree branches, and power lines).
• Keep the sensors clean at all times. DO NOT scratch or tamper with the sensors. DO
NOT use the aircraft in dusty or humid environments.
• Vision system cameras may need to be calibrated after being stored for an extended
period. A prompt will appear in DJI Fly and calibration will be performed automatically.
• DO NOT fly when it is rainy, smoggy, or the visibility is lower than 100 m.
• Check the following each time before takeoff:
a. Make sure there are no stickers or any other obstructions over the glass of the
infrared sensing system and vision systems.
b. Use soft cloth if there is any dirt, dust, or water on the glass of the vision systems
and infrared sensing system. DO NOT use any cleaning product that contains
alcohol.
c. Contact DJI Support if there is any damage to the lenses of the infrared sensing and
vision systems.
• DO NOT obstruct the infrared sensing system and vision systems.
• The aircraft can fly at any time of the day or night. However, the vision systems become
unavailable when flying the aircraft at night. Fly with caution.
