The Upload button starts and stops the upload service. The upload button with a green check signifies the upload program is running and the same button when shown with a red x signifies the upload service is stopped. If there is a poor internet connection the user can turn off the upload service. If there is a good internet connection the upload service should be running in the background to transfer images and session log files during the capture process. Please refer to the Troubleshooting section for instructions on transferring data from a WIB™ Unit that is offline.
