User Manual
Follow the steps below to use Vision Positioning:
1. Toggle the flight mode switch to P-mode.
2. Place the aircraft on a flat surface. Note that the Vision Positioning system cannot
work properly on surfaces without clear pattern variations.
3. Turn on the aircraft. The aircraft status indicator will flash green two times, 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 affected by the surface over which it is
flying. The ultrasonic sensors may not be able to accurately measure distances when operating
above sound-absorbing materials. In addition, the camera may not function correctly in
suboptimal environments. The aircraft will switch from P-mode to A-mode automatically if neither
GPS nor Vision Positioning System are available. Operate the aircraft with great caution in 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 10 m/s at 2 meters or over 5 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 the same design).
Flying over inclined surfaces that will deflect sound waves away from the aircraft.
Assisted Breaking from Obstacle Sensing System
Powered by the Obstacle Sensing System, the aircraft will now be able to actively initiate breaks when
obstacles are detected direct ahead of the aircraft. Note that Obstacle System works best when light
condition is ideal and the obstacle does not have feature-less pattern. In addition, the aircraft speed
cannot exceed over 8 meter/second so that the aircraft can break and stop at the safe distance.
