* Measurement accuracy depends on various factors. This value is obtained under normal conditions with an unobstructed view, good satellite distribution, low ionospheric activity, and no electromagnetic interference or multipath effects.

** Base station calibration coordinate accuracy depends on various factors. For surveying, high-precision flight paths, etc., it is recommended to calibrate during periods of inactive ionosphere, in open, unobstructed environments with no electromagnetic interference or multipath effects, using four or more GNSS systems.

*** Intense vibrations and rapid rotations can affect the accuracy of the inertial measurement unit.

Measured in an unobstructed outdoor environment free of interference. The above data shows the farthest communication range for one-way, non-return flights under each standard. Always pay attention to RTH reminders in the app during your flight.

FCC

Between the aircraft and the relay station: 25 km

Between the relay station and the remote controller/DJI Dock 3: Recommended within 1 km; maximum 3 km (unobstructed, free of interference)

SRRC

Between the aircraft and the relay station: 12 km

* The relay station should be deployed only after a field survey. If there is interference or obstruction at the chosen location, and the survey result is "Not suitable for deploying dock," "Unable to use RTK positioning," or indicates other unsuitable conditions, the site is not recommended. This may affect functions such as relay station upgrade and log download. It is recommended to install the relay station on rooftops, tower tops, or other elevated, unobstructed, and interference-free locations.

** Measured in an unobstructed outdoor environment free of interference. The above data shows the farthest communication range for one-way, non-return flights under each standard. Always pay attention to RTH reminders in the app during your flight. The relay station should be placed in an elevated, unobstructed location to ensure clear communication between the remote controller and the aircraft.

Strong interference: City centers, approx. 1.5-5 km

Medium interference: Suburban areas, approx. 5-15 km

Micro interference: Remote areas/seasides, approx. 15-25 km

Data is tested under FCC standards in unobstructed environments of typical interference. Only to serve as a reference and provides no guarantee as to the actual flight distance.

Low Interference and Obstructed by Buildings: approx. 0-0.5 km

Low Interference and Obstructed by Trees: approx. 0.5-3 km

Data is tested under FCC standards in unobstructed environments of typical interference. Only to serve as a reference and provides no guarantee as to the actual flight distance.

1. In normal temperature environments, charging power will be limited if the device shell temperature exceeds 48°C (118.4°F). Full power charging will resume after cooling.

2. After storage/use in low temperatures, the device needs to be brought to a normal temperature environment and allowed to warm up until the internal battery temperature is >0°C (32°F) before charging.

3. After storage/use in high temperatures, the device needs to be brought to a normal temperature environment and allowed to cool down until the internal battery temperature is <45°C (113°F) before charging.
