Flight Environment Selection
1. Fly your drone in an open field far away from densely populated areas, buildings, and facilities with electromagnetic interference.
2. During flight, keep away from GEO Zones or Restricted Zones to avoid forced landing and signal loss due to mistakenly entering these zones.
3. It is not recommended that you fly your drone in scenic spots, historical sites, parks, and the vicinity of government and military institutions. These places are highly likely to be restricted despite not officially being delimited as GEO Zones. Your drone may be forced to land, and flight may even be illegal in serious cases. Before a flight, it is recommended that you check whether GEO Zones or Restricted Zones exist.
4. Do not fly drones near facilities with electromagnetic interference. Common sources of electromagnetic interference include high-power radars, Wi-Fi hotspots, routers, Bluetooth devices, high-voltage power lines, high-voltage transmission stations, mobile phone base stations, and TV broadcast towers. When flying a drone in these areas, the wireless transmission of the drone will be interfered. If the interference is very strong, the drone signal may be stuck or even disconnected.
5. Do not operate the drone in high-temperature or low-temperature environments for a long time. The maximum and minimum operating temperatures of DJI Mavic Series, DJI Air Series, DJI Mini Series, DJI FPV, and Phantom 4 Series are 40°C and 0°C, respectively (the minimum operating temperature of DJI Mavic 3, DJI Mini 3 Pro, and Mavic Air 2 is -10°C). Flying a drone in high-temperature or low-temperature environments may lead to flight accidents.
1. Check the remote controller and battery power before the flight. In the case of sufficient power, you can get a longer battery life and better shooting experience.
2. Install the propellers properly and check whether the propellers are damaged or bent and whether propellers can rotate in all directions.
3. Connect your mobile device to the remote controller. Power on the remote controller and then the drone, and fully extend the antennas of the remote controller. Confirm the linking status and check whether any warnings are reported in the app after self-check, such as compass, IMU, and vision system errors. Observe and check whether the signal at the take-off location is adequate for image transmission. When "Ready to Go " appears and the app notifies that the Home Point has been refreshed, the drone is ready to take off.
4. It is recommended that you set “Remote Controller Signal Lost” to "RTH". (This setting allows the drone to automatically return when the drone is disconnected to the remote controller. You can refer to the settings in the following figures.) Observe the height of surrounding obstacles and set the RTH altitude in the app to a value greater than the height of the surrounding obstacles to avoid a collision during RTH.
1. Tap the three dots (...) in the upper right corner of the screen.
2. Go to “Safety”, scroll up to the bottom, and tap “Advanced Safety Settings”.
3. Select RTH for "Signal Lost".
DJI GO 4/DJI GO
1. Go to "Main Controller Settings" and swipe up to the bottom.
2. Tap "Advanced Settings".
3. Set "Remote Controller Signal Lost" to RTH.
Operations After Takeoff
1. Ensure that the antennas of the remote controller are facing the flight direction of the drone. Always pay attention to the signal strength of the current image transmission.
For details about the antenna orientation of the remote controller, see Introduction to the Orientation of the Remote Controller Antennas. If the app prompts that the current signals are weak or the image transmission signal is lost, adjust the antenna angle of the remote controller in line with the drone. Ensure that no obstacles exist between the remote controller and the drone. Otherwise, the signal is prone to being lost.
2. If the image transmission signal is lost but the drone is still under control, adjust the antenna angle of the remote controller in line with the drone. In the lower-left corner of the app, tap the map to view the current location and real-time flight path of the drone. Then, control the drone to fly back based on the flight path in the flight map. Pay attention to the height of the surrounding buildings to avoid collisions. If the connection cannot be resumed, immediately press and hold the Smart RTH button on the remote controller and release the button when the remote controller makes a beeping sound. Go to the Home Point recorded on the app and wait for the drone to return.
Note that if the Home Point was refreshed during use, go to the new Home Point to wait for the drone to return.
3. Operate the drone in a cool place and try to avoid direct sunlight on the mobile device or remote controller. If the temperature of the mobile device or remote controller is too high, the mobile device or remote controller may automatically shut down.
What to Do When Drone Flies Away
To avoid losing your drone, the best thing to do would be to search for their drone in that last known location. Be sure to be careful and remain calm.
Please take care of your personal safety during your search for the aircraft in the event of an accident (hanging high or falling into the water, etc.).
