2
Rotate your sensor placement sites, and do not use the
same site for two sensor sessions in a row. Using the same
site 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
to measure glucose. Insertion in those areas might affect
sensor accuracy and could result in you missing severe
hypoglycemia (low blood glucose) or hyperglycemia (high
blood glucose) events.
• Avoid injecting insulin or placing an insulin pump infusion
set within 3 inches of the sensor. The insulin might affect
sensor accuracy and could result in you missing severe
hypoglycemia (low blood glucose) or hyperglycemia (high
blood glucose) events.
• Do not use the sensor if its sterile package has been
damaged or opened. Using an unsterile sensor might
cause infection.
• To calibrate the system, do enter the exact blood
glucose value that your blood glucose meter displays
within 5 minutes of a carefully performed blood glucose
measurement. Do not enter sensor glucose readings for
calibration. Entering incorrect blood glucose values, blood
glucose values obtained more than 5 minutes before entry,
or sensor glucose readings might affect sensor accuracy
and could result in you missing severe hypoglycemia
(low blood glucose) or hyperglycemia (high blood
glucose) events.
• Do not calibrate if your blood glucose is changing at a
signicantrate,typicallymorethan2mg/dLperminute.
Do not calibrate when your receiver screen is showing
