Once a new sensor is inserted by your health care professional and paired with the transmitter using the Eversense® App, it will start the 24-hour warm-up phase. Once the 24-hour warm-up phase is completed, you will begin the Initialization Phase.
Initialization Phase (after 24-hour Warm-Up Phase)
During this phase, 4 finger stick blood glucose meter tests are required.
The sensor requires a 24-hour Warm-Up Phase to stabilize in your body before glucose values will be collected by the smart transmitter. During the Warm-Up Phase, you do not need to wear the smart transmitter. If you decide to wear the smart transmitter over the sensor during this time, you will receive a message on the app indicating the Warm-Up Phase is in progress. Once the Warm-Up Phase is complete, turn ON the smart transmitter and place it over the sensor with the Eversense® adhesive patch. The system will prompt you to calibrate using the app.
The Eversense® 365 CGM System provides readings within 40 – 400 mg/dL range every 5 minutes.

The Eversense® 365 Continuous Glucose Monitoring (CGM) System is indicated for continually measuring glucose levels for up to one year in people (18 years and older) with diabetes. The system is indicated for use to replace fingerstick blood glucose (BG) measurements for diabetes treatment decisions. Fingerstick BG measurements are required for calibration one time a week after day 13, and when symptoms do not match CGM information or when taking medications of the tetracycline class. The sensor insertion and removal procedures are performed by a health care provider. The Eversense 365 CGM System is a prescription device; patients should talk to their health care provider to learn more.
