Compliance with regulations
The scanner uses point-to-point Wi-Fi and Bluetooth to operate. You will need an Internet connection initially to download the Clarius App to your Android or iOS smart device and if you want to save images to the Clarius Cloud or transmit images via DICOM (available mid-2017). To use the scanner outside an existing wireless network, select "Wi-Fi Direct" in the scanner selection page (this is the default option), and once booted, the App will prompt you to connect to the Wi-Fi Direct network of the scanner.
