Do not accept incoming calls, do not switch to other applications, and do not turn off your mobile device during the flight. This will cause the flight to stop and the drone will need to be re-run along the route from the beginning.
During the flight, the operator needs to direct the remote control antennas towards the drone to ensure better radio communication quality. Avoid any obstacles between the remote control and the drone, such as power lines, buildings, terrain and landscape elements). This can lead to a sharp decrease in the quality of radio communication and stop the flight of the drone on a flight mission. During the flight, the operator must carefully monitor the number of visible satellites, battery charge, radio quality and camera image quality. It is recommended to land the drone after completing the route on the palm of your hand to avoid damaging the propellers. At the end of each flight, be sure to check the initialization status of the TOPODRONE DJI Air 2S PPK receiver. If the LED indication does not match the correct operation, check the connection of the GNSS antenna to the receiver and the operability of the TOPODRONE DJI Air 2S PPK memory card. If necessary, perform this route again. [](https://knowledge.topodrone.com/uploads/images/gallery/2024-12/RNtimage.png)
