you see this screen, it means the CGM session
has ended. Press the
this screen.
Contact your healthcare professional. You may
need to remove the sensor yourself or your healthcare professional
might help you remove it and insert a new sensor, if appropriate.
To help improve future sensor performance:
• Make sure the sensor is not expired.
• Make sure the transmitter is snapped in.
• Make sure the sensor pod is not dislodged or peeling up.
• Make sure nothing is rubbing the sensor pod (i.e. clothing, seat belts,
etc.).
• Make sure you have selected a good insertion site (see Chapter 6,
Section 6.3, Choosing an Insertion Site).
• Make sure the insertion site is clean and dry prior to sensor insertion.
