Vision System
1. The Vision System cannot work properly over surfaces that do NOT have clear pattern
variations. The Vision System is only effective when the aircraft is at altitudes of 0.5 to 30
meters. If the aircraft is above the Attitude Range (8 meters), the Vision Positioning function
may be affected, y with caution.
2. The Vision System may NOT function properly when the aircraft is ying over water or snow-
covered areas.
3. Note that the Vision System may NOT function properly when the aircraft is ying too fast (ying
at high speeds (over 10 m/s (32.8 feet/s) at 2 meters (6.6 feet) or over 5m/ s (16.4 feet) at 1
meter (3.3 feet) ).
4. Operate the aircraft cautiously when in any of the following situations:
a. Flying over monochrome surfaces (e.g., pure black, pure white, pure red, pure green).
b. Flying over highly reective 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 (> 10,000 lux) surfaces;
g. Flying over surfaces that strongly reect or absorb infrared waves (e.g. mirror);
h. Flying over surfaces without clear patterns or texture;
i. Flying over surfaces with identical repeating patterns or textures (e.g. tiles with same design);
j. Flying over obstacles with surfaces that are too small.
5. Keep the sensors clean at all times. DO NOT temper with the sensors.
6. The Vision System may not be able to recognize patterns on the ground in low light conditions
(less than 100 lux).
7. The Vision System is not able to brake and stop the aircraft at a safe distance from an obstacle if
the aircraft speed exceeds 10 m/s (22 mph).
8. Camera calibration is required if the aircraft suffers from crashing. Calibrate the front cameras
if DJI GO 4 app prompt you to do so.
TapFly
To prevent serious injury or property damage, observe the following guidelines:
1. DO NOT instruct the aircraft to y towards people, animals, small and ne objects (e.g. tree
branches and power lines) or transparent objects (e.g. glass and water).
2. Watch out for potential obstacles in your surrounding area (especially on the rear, left, and
right sides of the aircraft) and stay clear of them to avoid accidents.
3. Be prepared to take control of the aircraft by pressing the stop button on the screen to exit
TapFly in case of an emergency.
1. There may be deviations between the expected and actual paths for your TapFly selection.
2. The selectable range on the screen is limited. You cannot make TapFly selections near the
upper or lower edges of the screen.
3. The TapFly mode may NOT function properly when the aircraft is ying over water or snow-
covered areas.
4. Be extra cautious when ying in extremely dark (< 300 lux) or bright (> 10,000 lux) environments.
