Aircraft
Follow the steps below to use Vision Positioning:
1. Toggle the switch to “P” as shown the figure to the right:
2. Place the aircraft on a flat surface. Notice that the Vision Positioning system cannot work properly on surfaces
without pattern variations.
3. Power on the aircraft. The aircraft status indicator will flash twice in green light, which indicates the Vision
Positioning system is ready. Gently push the throttle up to lift off, and the aircraft will hover in place.
The performance of your Vision Positioning System is subject to the surface you are flying over. The
ultrasonic waves may not be able to accurately measure the distance over sound absorbing
materials, and the camera may not function correctly in suboptimal environments. The aircraft will switch
from “P” mode to “A” mode automatically if both GPS and Vision Positioning System are not available.
So operate the aircraft cautiously when in any of the following situations:
Flying over monochrome surfaces (e.g. pure black, pure white, pure red, pure green). Flying over a
highly reflective surfaces.
Flying at high speeds(over 8 m/s at 2 meters or over 4 m/s at 1 meter).
Flying over water or transparent surfaces.
Flying over moving surfaces or objects.
Flying in an area where the lighting changes frequently or drastically.
Flying over extremely dark (lux < 10) or bright (lux > 100,000) surfaces. Flying
over surfaces that can absorb sound waves (e.g. thick carpet).
Flying over
surfaces without clear patterns or texture.
Flying over surfaces with identical repeating patterns or textures (e.g. tiles with same design).
Flying over inclined surfaces that will deflect sound waves away from the aircraft.
Keep the sensors clean at all times. Dirt or other debris may adversely affect the effectiveness
of the sensors.
The effective hovering altitudes of the aircraft is from 0 to 2.5 meters.
Vision Positioning system may not function properly when the aircraft is flying over water.
Vision Positioning system may not be able to recognize pattern on the ground in low light
conditions (less than 100 lux).
Do not use other ultrasonic devices with frequency of 40 KHz when Vision Positioning system is
in operation.
Vision Positioning system may not be able to stabilize the aircraft when flying close to the
ground (below 0.5 meters) in fast speed.
Keep the animals away from the aircraft when Vision Positioning system is activated. The sonar
sensor emits high frequency sound that is only audible to some animals.
Flight Recorder
Flight data is automatically recorded to the SD card. This includes flight duration, orientation, distance, aircraft status
information, speed, and other parameters.
Attaching and Detaching the Propellers
Use only DJI approved propellers with your Phantom 4. The grey or black nut on the propeller
indicates
the rotation direction of the propeller and where it should be attached. To attach the propellers
properly, match the nut with the dots on the motors of your Phantom 4.
