The 3D Infrared Sensing System is only active in Beginner mode and Tripod Mode. Fly with
caution.
The performance of your Vision System and Infrared Sensing System are affected by the surface

operating above 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 neither
GPS nor Vision System and Infrared Sensing System are available. Operate the aircraft with
great caution in the following situations:
a) Flying over monochrome surfaces (e.g. pure black, pure white, pure red, pure green).

c) Flying at high speeds of over 31mph (50kph) at 2 meters or over 11mph (18kph) at 1 meter.
d) Flying over water or transparent surfaces.
e) Flying over moving surfaces or objects.
f) Flying in an area where the lighting changes frequently or drastically.
g) Flying over extremely dark (lux < 10) or bright (lux > 100,000) surfaces.
h) Flying over surfaces that can absorb sound waves (e.g. thick carpet).
i) Flying over surfaces without clear patterns or texture.
j) Flying over surfaces with identical repeating patterns or textures (e.g. tiling).

m) DO NOT position the sides of two aircraft toward each other to avoid interference between
the 3D infrared modules.
n) DO NOT cover the protective glass of the infrared module. Keep it clean and undamaged.
Keep sensors clean at all times. Dirt or other debris may adversely affect their effectiveness.
Vision Positioning is only effective when the aircraft is at altitudes of 0.3 to 10 meters.

The Vision 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 System is in
operation.
Keep animals away from the aircraft when Vision Positioning is activated. The sonar sensor
emits high frequency sounds that are audible to some animals.
Assisted Braking from Obstacle Sensing
Powered by the Obstacle Sensing, the aircraft will now be able to actively brake when obstacles
are detected around the aircraft. Note that Obstacle Sensing function works best when lighting
