Storage
During a sensor's shelf life, store it between 36° F-77° F. While you don't need to keep your
sensor in a refrigerator, you can as long as the refrigerator is between 36° F-77° F.
Never store sensors and/or sensor packages in a freezer.
Storing the sensor incorrectly might cause the sensor glucose readings to be incorrect,
resulting in you missing a severe low or high glucose event.
Precautions
Expiration Date
Don't use expired sensors. Before inserting, always check the package label for the
expiration date using the YYYY-MM-DD format.
If past the expiration date, don't use because the sensor glucose readings might not be
accurate, resulting in you missing a severe low or high glucose event.
Sensor Package
Don't use sensor if its sterile package has been damaged or opened. Using a non-sterile
sensor might cause infection.
Clean and Dry Before Using
Before opening the sensor package, wash your hands with soap and water, then dry. If your
hands are dirty while inserting the sensor, you may contaminate the insertion site and get
an infection.
Before sensor insertion, clean the skin with alcohol wipes to prevent infections. Don't insert
the sensor until the cleaned insertion site is dry, and free from any lotions or perfumes.
If your insertion site is not clean and completely dry, you run the risk of infection or the
sensor pod not sticking and falling off.
Sensor Placement
Change the site where you place the sensor with each new insertion. Using the same site too
often might not allow the skin to heal, causing scarring or skin irritation.
Sensor placement is important. Make sure the area you place your sensor won't:
• Be bumped, pushed, or squeezed
• Have scars, tattoos, or irritation
Insertion in these areas might affect sensor performance, resulting in you missing a severe
low or high glucose event.
