Using the E4 in recording mode allows you to record the data in its flash memory.
While the E4 is in recording mode, up to 60 hours of data can be stored in the device's flash memory.
Data remains on the device until a USB connection is made to a Mac or Windows PC running E4 Manager Software. E4 Manager transfers recorded sessions to your PC’s storage, clears the E4’s memory and syncs the clock. If an internet connection is present it also uploads session data to Empatica Connect servers for processing, visualization, and retrieval.
