2. The voltage on the aircraft can reach 58.8 V. Read the battery's
safety guidelines and take necessary precautions when handling
the batteries to ensure your own safety.
3. DO NOT splash the battery with an excessive volume of water.
Aerial-Electronics System
To avoid component malfunction, serious injury, and property
damage, observe the following rules:
1. The aerial-electronics system includes a built-in GNSS/RTK module
and OcuSync module. DO NOT place objects on the system or
obstruct the system, as this will reduce the GNSS signal and
remote control signal strength.
2. DO NOT touch or let your hands or body come in contact with the
metal parts of the aerial-electronics system when powering on or
after flight as they may be hot.
3. When using with multiple aircraft, including T20 and other
aircraft, make sure that the distance between each aircraft is
more than 10 m to avoid interference.
4. DO NOT use water to clean the barometer on the back of the aerial-
electronics system.
5. If the USB-C port is not in use, make sure to attach the waterproof
cover. Otherwise, water may enter the port which can short circuit.
6. When operating at night, DO NOT look directly at the spotlight to
avoid damaging your eyes.
Compass
To avoid component malfunction, serious injury, and property damage,
observe the following rule:
1. Land immediately when obvious drifting occurs in flight such as if the
aircraft does not fly in a straight line.
Calibrate the compass when the app prompts you to do so. Observe
the following rules when calibrating your compass:
1. It is important to calibrate the compass. The calibration result will
affect the flight safety. The aircraft may malfunction if the compass is
not calibrated.
2. DO NOT calibrate your compass where there is a chance of strong
magnetic interference. This includes areas where there are utility
poles or walls with steel reinforcements.
3. DO NOT carry ferromagnetic materials with you during calibration
such as keys or mobile phones.
4. If the aircraft status indicators show a blinking red light, compass
calibration has failed. Please recalibrate.
5. After calibrating successfully, the compass may be abnormal
when you place the aircraft on the ground. This may be because
of underground magnetic interference. Move the aircraft to another
location and try again.
Propulsion System
To avoid serious injury to yourself or others, which may be caused
by the rotating propellers and motors, observe the following rules:
Propellers
1. Check if the propellers are in good condition before each flight.
Replace aged, chipped, or broken propellers.
2. Power off the aircraft before touching the propellers.
3. Be aware of the sharp edges of the propellers when mounting or
removing the propellers.
4. Make sure that propellers are unfolded and firmly tightened before
each flight.
5. Stay away from the rotating propellers and motors to avoid injuries.

Motors
1. Make sure that the motors are securely mounted and rotating
smoothly.
2. DO NOT attempt to modify the structure of the motors.
3. DO NOT touch or let your hands or body come in contact with the
motors after flight as they may be hot.
To avoid component malfunction, serious injury, and property
damage, observe the following rules:
1. DO NOT block any of the ventilation holes on the motors.
1. Keep the motors free of dust.
2. If a motor is stuck and unable to rotate freely, execute the CSC to stop
the motors immediately.
3. Make sure the sound of the motors when powering on is normal.
Spraying System
To avoid component malfunction, serious injury, and property
damage, observe the following rules:
Pesticide Usage
1. Avoid the use of powder pesticides as much as possible as they
may reduce the service life of the spraying system.
2. Pesticides are poisonous and pose serious risks to safety. Only use
them in strict accordance with their specifications.
3. Residue on the equipment caused by splashes or spills when
pouring and mixing the pesticide can irritate your skin. Make sure
to clean the equipment after mixing.
4. Use clean water to mix the pesticide and filter the mixed liquid
before pouring into the spray tank to avoid blocking the strainer.
Clear any blockage before using the equipment.
5. Make sure to stay in an upwind area when spraying pesticide to
avoid bodily harm.
6. Wear protective clothing to prevent direct body contact with the
pesticide. Rinse your hands and skin after handling pesticides.
Clean the aircraft and remote controller after applying the pesticide.
7. Effective use of pesticides depends on pesticide density, spray
rate, spray distance, aircraft speed, wind speed, wind direction,
temperature, and humidity. Consider all factors when using
pesticides, but DO NOT compromise the safety of people, animals,
or the environment in doing so.
8. DO NOT contaminate rivers and sources of drinking water.
Sprinklers
1. Avoid using insoluble pesticides such as wettable powder.
2. The sprinklers are delicate parts. Clean them immediately after use.
3. DO NOT bend the hose in an arc tighter than its minimum bend
radius. This is to avoid creasing, which may compromise the
spraying effect.
4. Make sure to securely tighten the hose nuts to avoid liquid leakage.
Spray Tank
1. Make sure that the spray tank is firmly in place to avoid liquid
leakage.
2. The internal load of the spray tank must not exceed 20 kg.
Omnidirectional Digital Radar
To avoid component malfunction, serious injury, and property
damage, observe the following rules:
1. DO NOT touch or let your hands or body come in contact with the
metal parts of the radar module when powering on or immediately
after flight as they may be hot.
