• Sensor placement and insertion is not approved for sites
other than the belly (abdomen).
• If your transmitter or receiver case is damaged/cracked, do
not use it. This could create an electrical safety hazard or
malfunction, which might cause electrical shocks.
• Store the sensor at temperatures between 36° F - 77° F
for the length of the sensor’s shelf life. You may store the
sensor in the refrigerator if it is within this temperature
range. The sensor should not be stored in a freezer. Storing
the sensor improperly might cause the sensor glucose
readings to be inaccurate, and you might miss a low or high
blood glucose value.
2.5 PRECAUTIONS
• Before opening the sensor package, wash your hands with
soap and water, and let them dry. You may contaminate the
insertion site and suffer an infection if you have dirty hands
while inserting the sensor.
• Before inserting the sensor, clean the skin with a topical
antimicrobial solution, such as isopropyl alcohol, and allow
to dry. This may help prevent infection. Do not insert the
sensor until the cleaned area is dry so the sensor adhesive
will stick better.
• Change the site where you place the sensor with each
insertion. Using the same site too often might not allow the
skin to heal, and might cause scarring or skin irritation.
• Avoid inserting the sensor in areas that are likely to be
bumped, pushed or compressed or areas of skin with
scarring, tattoos, or irritation as these are not ideal sites
