Before starting with these general device workflows you will need to:
Install YP SDK and initialization within your PACS mobile app, as described in the SDK ReadMe (YP SDK or uSDK documentation)
Have the PACS mobile app register the mobile device with YP platform. This is a one-time activity that needs to be performed on first use after the mobile app is installed on a phone. It is recommended to deregister before uninstalling the mobile application from the phone. Refer to SDK ReadMe “Intermediary Device Registration“ section on how to register a mobile device.
