Upon downloading the app, the initial launch will initiate the download of audio data. It is recommended to download this data using a Wi-Fi connection due to the significant time it may take in a 3G environment. Even in a Wi-Fi environment with good signal strength, the download process may take approximately 10 minutes.

If the download is interrupted due to network disconnection or device sleep mode, the installation may fail. In such cases, please adjust the settings, such as extending the sleep time, and reinstall the app.

While the audio data can be saved on the SD card, please ensure that you have sufficient free space (around 200MB) before initiating the download.
