When there are multi-device in your system and required to set the same configurations, you could save or download the current configuration parameters to your device, then upload to other devices. After the device is restarted, the preset saved parameters will take effect.

"Preset configuration" – "Save current configuration", you can choose to save the required parameters and download, and the configuration name is customized.

When there are other devices on site or the parameters of your device are restored to the factory, you want to use the parameters previously set. You can upload the saved configuration file in "manage or load preset configuration", restart the device after loading, and the parameter configuration will take effect.
