After 14 days of usage your CGM will expire. When the CGM expires you will receive the message "Your sensor has expired. Please replace with a new one," as can be seen in the screenshot below. You can also monitor how many days you have remaining with the sensor by going to Settings -> Sensor Settings.
After you see the expiration message, you should do the following:
- Peel off the CGM by pinching a small part of the adhesive that is attached to your skin. Pull the adhesive up and toward the center of your CGM. The CGM should come off easily.
- Wrap the CGM in a tissue, toilet paper or paper towel and dispose of it in the trash. Don't worry, there is no needle in the CGM, so it is safe to throw out.
- Put on the new CGM. The process can reviewed here.
- Reactive the new CGM. The process can be reviewed here.
