Flight Safety

What should I be cautious of when using the DJI Digital FPV System alone?

When using the DJI Digital FPV System alone: 
1) Do not fly in areas with heavy signal interferences, for example, areas with strong Wi-Fi signals;
2) Do not fly your aircraft too far away or at too low of an altitude;
3) Disable the Wi-Fi of the external modules mounted on the aircraft to avoid signal interference.

 

What should I be cautious of when using the DJI Digital FPV System with multiple pilots in the same area?

Signal interference may occur when multiple DJI FPV Systems are operating simultaneously. To avoid this, refer to the instructions below:
1) Maintain a safe distance of at least 3 meters between each aircraft. Power on and choose a frequency channel for each aircraft one at a time. Avoid using the same frequency channel as other pilots. If live feeds begin to blur, restart all devices;
2) Pilots should avoid using the public channel simultaneously during flight as it may result in increased signal interference, blurry live feeds, and reduced image quality; 
3) If the frequency channel you choose is close to another pilot’s channel, ensure that your aircraft is at least 3 meters away from their goggles;
4) Maintain a distance of at least 3 meters between each pair of goggles;
5) If your live feed becomes blurry due to multiple pilots flying in the same area, restart your air unit. 

 

What should I be cautious of when choosing a frequency channel that is being used by another pilot?

It is not recommended to do so. If you enter a channel that is occupied, both pilots may be temporarily switched to the public channel, causing signal interference. Additionally, both users may lose control of their aircraft and may not be able to receive live video feeds.

 

What are the precautions when using the DJI FPV System in other countries or regions?

When using the DJI FPV System in other countries or regions, you must follow local radio regulations. Connect the DJI FPV System to DJI Assistant 2 (DJI FPV Series), and the software will automatically tune system settings according to local laws.

 

What are the precautions when using the DJI FPV Goggles?

When using the goggles in a sunlit area, avoid exposing the lenses to direct sunlight, as this may cause irreversible damage to the optics.

 

What are the precautions when using the DJI FPV Air Unit?

The DJI FPV Air Unit can generate a large amount of heat, so do not touch the air unit directly without first allowing it to cool. Avoid using the air unit for extended periods in high-temperature environments with little ventilation. Otherwise, the air unit will become hot and enter Low Power mode, affecting its performance.

 

What are the precautions when handling the antenna of the DJI FPV Air Unit?

The DJI FPV Air Unit utilizes an MMCX antenna. Since the inner pin is small, when pulling out the antenna, hold the air unit with one hand, pull the antenna gently with the other hand, making sure to remove it horizontally. Installing or pulling the antenna out too forcefully may cause the inner pin and the collar to fall off or become damaged.
