GDU-Tech S400 4G Professional Drone Camera Instruction Manual

GDU-Tech S400 4G Professional Drone Camera

Please follow the steps below to install the kit in the aircraft：

1. Insert the Nano-SIM card into the 4G module’s SIM card slot. Cover the card slot’s protective rubber plug.
2. Fix the 4G module to the installation position at the bottom of the aircraft. Tighten the thumbscrews.
3. Connect the 4G module’s connection cable to the aircraft.

Ensure that the 4G module’s connection cable is connected to the aircraft firmly. The LTE backup link is prone to be affected by the operator’s real- time network environment. It is recommended to use a non-IOT network card. Use with caution and pay attention to signal quality

Disclaimer

Thank you for using this GDU product. To ensure a positive operating experience and to protect your legal rights, please carefully read this
Manual before use: Please strictly follow the content of this Manual. GDU takes no responsibility for any loss caused by improper usage (including but not limited to altering the product’s structure or disassembling the product without authorization).

Use

1. Ensure that the remote controller is properly inserted with an SIM card or connected to Wi-Fi, and the network can be accessed normally.
2. Turn on the remote controller and the aircraft.
3. Launch the GDU Flight II App and enter the video transmission settings interface to set the HD and LTE links. There are the following modes:
   • Automatic mode: This mode HD is a master video transmission link HD. When there is interference with the video transmission signal, it will automatically switch to LTE video transmission.
   • When the video transmission signal is restored, the mode will be automatically switched back to the video transmission link.
   • Video transmission link mode: This mode only supports the video transmission link and does not support the LTE video transmission.
   • TE link mode: This mode is LTE link mode, and the LTE link is a master video transmission link. It will be switched to the video transmission link only when the LTE link fails. If it is not set again, it will not return to the LTE link.
   • The LTE link must be used with the A4G-S400 4G module. This function is not available if the A4G-S400 4G module (an optional accessory) is not installed.
   • Before takeoff, ensure that the A4G-S400 4G module and the wireless dongle have been fixed onto the aircraft to avoid them falling off due to heavy wind or aircraft vibration during the flight process.
   • The LTE backup link cannot be used with dual remote controllers.
   • Due to the LTE signal coverage issues, it is likely to encounter a signal dead zone, resulting in the aircraft going out of control. Before takeoff, be sure to set the aircraft behaviour (such as return altitude and HOME point) when the signal is weak based on the flight environment. If the signal is weak or lost due to the communication operator, GDU is not liable for any product damage and other issues caused by this.
   • The LTE backup video transmission function is supported only in areas with strong LTE base station signals. Due to legal restrictions, the recommended flight altitude should be ≤ 120 m (≤200 m for areas applied with an airspace).
   • The operating temperature of the A4G-S400 4G module is -20 to 55°C. Please do not use it in high-temperature environments.
   • For the LTE backup link, the remote controller can use Wi-Fi or a wireless dongle for access. If the wireless dongle is used to achieve connection, it is recommended to disable Wi-Fi
