dji AIR 3S - Network Requirements; Post-Flight Checklist

Due to certain restrictions on Android/iOS systems, if you receive a call, the DJI Fly app
may be restricted from using the 4G network in the background, which can lead to
unavailability of Enhanced Transmission. If the OcuSync link is disconnected at this time, it
will lead to failsafe RTH.
4G Network Requirements
The 4G network transmission speed is determined by the 4G signal strength of the
aircraft and the remote controller at the current position and the network congestion
level of the corresponding base station. The actual transmission experience is closely
related to the local 4G network signal conditions. The 4G network signal conditions
include both sides of the aircraft and the remote controller with various speeds. If the
network signal of either the aircraft or remote controller is weak, has no signal, or is busy,
the experience of 4G transmission may drop and lead to the video transmission freezing,
a delayed response of the controls, loss of video transmission, or loss of controls.
Therefore, when using Enhanced Transmission:
1. Make sure to use the remote controller and aircraft in locations where the 4G signal is
close to full for a better transmission experience.
2. If the OcuSync signal is disconnected, the video transmission may lag and stutter
when the aircraft relies fully on a 4G signal. Fly with caution.
3. When the OcuSync signal is poor or disconnected, make sure to maintain an
appropriate altitude during the ight. In open areas, try to keep the ight altitude
below 120 meters for a better 4G signal.
4. For ight in the city with tall buildings, make sure to set a suitable RTH altitude (higher
than the tallest building).
5. When the app prompts that the 4G signal is weak, y with caution.
7.6 Post-Flight Checklist
• Make sure to perform a visual inspection so that the aircraft, remote controller,
gimbal camera, Intelligent Flight Batteries, and propellers are in good condition.
Contact DJI support if any damage is noticed.
• Make sure that the camera lens and vision system sensors are clean.
• Make sure to store aircraft correctly before transporting it.
