5. Only use the Failsafe and Return-to-Home functions in case of
emergency, as they may be affected by the weather, the environment, or
any nearby magnetic elds.
6. The aircraft cannot avoid obstacles during the Failsafe RTH when lighting
condition is not ideal; therefore it is important to set an appropriate
Failsafe altitude before each ight.
7. When ying indoors, the aircraft cannot perform precision hovering when
ying above the surfaces that do not have a clear pattern. Refer to the
“Vision Positioning System” section for complete indoor ying criteria.
Low Battery
1. When the Critical Battery Level Warning activates and the aircraft is
descending automatically, you may push the throttle up to maintain the
aircraft's altitude and navigate it to a more appropriate location for landing.
2. When battery warnings are triggered, promptly bring the aircraft back to
the Home Point or land to avoid losing power during ight and causing
damage to the aircraft, property, animals, and people.
Vision Positioning System
1. The Vision Positioning System cannot work properly over surfaces that
do NOT have pattern variations. The effective altitude for the Vision
Positioning System to function correctly is less than 13 meters above
ground level (AGL).
2. The Vision Positioning System may NOT function properly when the
aircraft is ying over water.
3. Keep your pets away from the aircraft when the Vision Positioning System
is activated, as the sonar sensors emit a high frequency sound that is
only audible to some pets.
4. Note that the Vision Positioning System may NOT function properly when
the aircraft is ying too fast or too low.
5. 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 at high speeds (over 10m/s at 2 meters or over 5m/s 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;
