3.     Troubleshooting

If you upload your Tandem pump but are missing some of your pump and/or CGM data when viewing in, we recommend you retry uploading with the “All data” option enabled in Uploader.

  • Open Uploader and log in if not already logged in.
  • Left-click the Uploadmenu (not the button) and left-click All data.

  • Now connect the pump via micro-USB and click the Upload button in the main Uploader window as seen in Step 2 of this guide.
  • This upload will take much longer as it is retrieving all the records from the pump and can take anywhere from 10-30 minutes, depending on the amount of data on the pump.
  • Once completed, log into digital Weband you should now see the previously missing data.
