The figure below shows the function that each control stick movement performs and uses Mode 2 as an example. In Mode 2, the left stick is used to control the altitude and heading of the aircraft while the right stick is used to control the forward, backward, left, and right movements.

The remote controller is able to reach its maximum transmission distance (FCC/NCC: 7 km (4.35 mi); SRRC: 5 km (3.11 mi); CE/KCC/MIC: 4 km (2.49 mi)) in an open area with no electromagnetic interference, and at an altitude of approximately 2.5 m (8.2 ft). Make sure to comply with local laws and regulations when using Multi-Aircraft Control mode.

Fly Safe

It is important to understand some basic flight guidelines, both for your protection and for the safety of those around you.

1.  Flying in Open Areas: pay attention to utility poles, power lines, and other obstacles. DO NOT fly near or above water, people, or animals.
2.  Maintain Control at All Times: keep your hands on the remote controller and maintain control of the aircraft when it is in flight, even when using intelligent functions such as the Route and A-B Route operation modes and Smart Return to Home.
3.  Maintain Line of Sight: maintain visual line of sight (VLOS) with your aircraft at all times and avoid flying behind buildings or other obstacles that may block your view.
4.  Monitor Your Altitude: for the safety of manned aircraft and other air traffic, fly at altitudes lower than 100 m (328 ft) and in accordance with all local laws and regulations.

Visit https://www.dji.com/flysafe for more information on critical safety features such as GEO zones.

Flight Environment Requirements

1.  DO NOT use the aircraft to spray in winds exceeding 18 kph (11 mph).
2.  DO NOT use the aircraft in adverse weather conditions such as winds exceeding 28 kph (17 mph), heavy rain exceeding 25 mm (0.98 in) in 12 hours, snow, or fog.
3.  DO NOT fly more than 4.5 km (14,763 ft) above sea level.
4.  The DJI Agras app will intelligently recommend the payload weight limit for the tank according to the current status and surroundings of the aircraft. Do not exceed the recommended payload weight limit when adding material to the tank. Otherwise, the flight safety may be affected.
5.  Make sure that there is a strong GNSS signal and the D-RTK antennas are unobstructed during operation.

Return to Home (RTH)
The aircraft will automatically return to the Home Point in the following situations: Smart RTH: user presses and holds the RTH button. Failsafe RTH: the remote controller signal is lost.* If there is an obstacle within 20 m of the aircraft, the aircraft decelerates and brakes and hovers. The aircraft will exit RTH and wait for further commands. If RTH is triggered during Route operations, the aircraft can plan a flight path for RTH to circumvent the obstacles added when planning a field. The aircraft will RTH or hover if the remote controller signal is lost. The action can be set in the app. Failsafe RTH will only be available if RTH is set. Obstacle avoidance is disabled when the aircraft is in Attitude mode, which it enters in situations such as when the GNSS signal is weak. Note that obstacle avoidance is unreliable when using the aircraft in environments where the radar module cannot operate normally. Extra caution is required in such situations.

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.  Use clean water to mix the pesticide and filter the mixed liquid before pouring into the spray tank to avoid blocking the strainer.
4.  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.
5.  DO NOT compromise the safety of people, animals, or the environment during operation.

It is important to understand the basic flight guidelines, both for your protection and for the safety of those around you. Make sure to read the disclaimer and safety guidelines.

•  Maintain control of the remote controller as long as the motors are running.
• DO NOT stop the motors mid-flight unless in an emergency situation where doing so will reduce the risk of damage or injury.
• It is recommended to use Method 1 to stop the motors. When using Method 2 to stop the motors, the aircraft may roll over if it is not completely grounded. Use Method 2 with caution.
•  After landing, power off the aircraft before turning off the remote controller.

Starting Operations
After the operation area and obstacles have been measured and settings have been configured, the DJI Agras app uses a built-in intelligent operation planning system to produce a flight route based on the user’s input. Users can invoke an operation after planning a field. The aircraft will begin the operation automatically and follow the planned flight route. In scenarios with complicated terrain, Phantom 4 RTK and DJI TERRATM can be used to plan flight routes and import routes to the DJI Agras app for operation. Refer to the Agras T10 User Manual for more information.
Field Planning
The DJI Agras app supports flight route planning by flying the aircraft to waypoints, obstacles, and calibration points or by walking to these points carrying a remote controller, a remote controller with an RTK dongle, or an RTK device. The following route has been planned by walking to the points with a remote controller. When the RTK dongle (sold separately) is connected to the USB-A port on the remote controller, “Walk with RTK” can be selected during field planning to plan operations to centimeter-level precision. The remaining steps are the same as the instructions for walking with a remote controller.

1. Power on the remote controller. Launch DJI Agras.
2. Tap Plan Field, select Walk with RC.
3. Wait until the GNSS signal is strong. Positioning accuracy may vary by +/-2 meters.
4. Walk with the remote controller alongside the boundary of the operation area and tap Add Waypoint C2 at turning points.
5. Walk to each obstacle in turn and tap Obstacle Mode C1.*
