Flight Modes
To avoid serious injury and property damage, observe the following rule:
1. DONOTswitchfromStandardmodetoFastmodeunlessyouaresufcientlyfamiliarwith
theaircraft’sbehaviorineachightmode.
1. Standardmode(default):TheaircraftutilizestheVisionPositioningSystemtoautomaticallystabilize
itself.Themaximumightattitudeangleis9°andthemaximumightspeedis9mph(14.4kph).
2. Fastmode:TheaircraftutilizestheVisionPositioningSystemtoautomaticallystabilizeitself.The
maximumightattitudeangleis25°andthemaximumightspeedis18mph(28.8kph).
To switch from Standard mode to Fast mode users must read and agree to the disclaimers and
warnings that appear in the Tello app. Make sure you understand the differences between the two
ightmodes.
The aircraft will revert to Attitude mode when the Vision Positioning System is unavailable. In Attitude
mode,theaircraftiseasilyaffectedby itssurroundings,which mayresultin horizontalshifting.
Therefore, the aircraft cannot position or auto-brake in this mode. When the aircraft enters Attitude
mode,landinasafeplaceassoonaspossibletoavoidhazards.
Onlylandthe aircraftonat surfaces.DONOT landtheaircraft overwater,grass orsand.When
usingPalmLand,ensureyourpalmisrightundertheaircraftandkeepyourpalmat.
Low Battery
1. When battery warnings are triggered, promptly bring the aircraft back or land the aircraft to avoid
losingpowerduringightandcausingdamagetotheaircraft,property,animals,andpeople.
2. When the Critical Battery Level warning appears the aircraft will start to descend automatically.
You may push the throttle up to maintain the aircraft's altitude and navigate the aircraft away from
people and obstacles to a more appropriate location for landing.
Vision Positioning System
1. The Vision Positioning System cannot work properly over surfaces that do not have clear pattern
variations. The Vision Positioning System is only effective when the aircraft is at altitudes of 0.3 to
10 m. The Vision Positioning System works best at altitudes of 0.3 to 6 m. If the aircraft is beyond
this range, the Vision Positioning function may be affected, so extra caution is required.
