Your sensor has a 12 hour grace period at the end of the session. You'll get alerts letting you know your sensor session or grace period will end. The grace period gives you more time to replace your sensor so you can do it when it's convenient for you. You can either end your sensor early or wait until it automatically ends.

To end your session early, go to Menu and select:

Replace Sensor: If you want to start a new sensor immediately
or
Stop Sensor Session: If you want to stop this sensor without starting a new one

The other option is to wait until your sensor automatically ends, at this point the receiver will tell you it is time to start a new sensor.
