Protection Rating
Under controlled laboratory conditions, the Autel Alpha aircraft (with smart batteries installed)
can achieve an IP55 protection rating following IEC 60529 standards. The protection rating is not
permanent and may degrade due to long-term wear and tear.
It is not recommended to fly in rainy conditions. In case of rain during the flight, abort the
flight and return to a safe location promptly.
Before flight, make sure that the battery connector, battery compartment interface, battery
surface, and battery compartment surface are dry and water-free before inserting the battery
into the aircraft fuselage.
After completing the flight, wipe off the rainwater on the aircraft fuselage before folding and
storing the aircraft to prevent water from entering the aircraft and affecting its protective
performance.
Make sure that the battery connector and surface are dry and water-free before charging the
battery.
Damage caused by immersion in liquid is not covered by the warranty.
The aircraft does not have an IP55 protection rating in the following conditions:
The aircraft is not installed with a battery or the battery is not properly installed.
The rubber protective cover at the interface of the fuselage or the gimbal is not properly
installed.
There are other possible damage on the fuselage, such as shell cracks or waterproof adhesive
failure.
Please strictly comply with the usage environment restrictions of the aircraft. Using the
aircraft beyond specified conditions may lead to aircraft damage or safety incidents.
Noise
The Autel Alpha aircraft will generate a certain level of noise during operation. You should
understand local noise pollution prevention regulations in advance and set an appropriate flight
altitude or safe distance to ensure that it does not disturb other individuals, groups, or
organizations.
A-weighted sound power level
The Autel Alpha aircraft has passed sound power test conducted by relevant third-party testing
organizations with qualification. The results comply with the regulations concerning unmanned
aerial vehicles in the European Union.
