  • Users are solely responsible to manage the back up of their acquired images or any digital data
    • TEMs images are temporally stored on the second computer PC, next to each our TEM machine
    • at the end of the TEM session, is user responsibility to copy the data to the sucure location for later use and back up
    • data older than 1 year can be deleted by PFMU without notice in order to free hard drive free space
