Warnings, Cautions And Important Notes
Important Notes About System Performance
The following items describe situations that could lead to inaccurate or unreliable continuous glucose
results.
Cautions:
Movement of the sensor support mount or excessive perspiration at the sensor insertion site due to •
activities like vigorous exercise or bumping against objects may lead to poor adhesion of the support
mount to the skin and cause the sensor to dislodge. If the sensor dislodges due to the sensor support
adhesive failing to adhere to the skin, you may get unreliable results or no results. The system may not
provide a warning in such circumstances. Choose the proper sensor insertion site when inserting the
sensor and prepare the site by following the instructions for site preparation.
If your results from the Continuous Monitoring mode seem erroneous, check and make sure that the
•
sensor has not dislodged. If you notice the sensor is dislodged from the skin, or if you see that the adhesive
on your overbandage or the sensor support mount is coming loose, discard the old sensor and insert a
new sensor.
The FreeStyle Navigator system includes built-in self-checks to detect conditions that may cause
•
the sensor to not function properly. On rare occasions the system may not be able to detect all such
conditions (for example if the adhesive peels up from your skin), and you may get inaccurate results in
the Continuous Monitoring mode. If you believe your results are not reliable, or are inconsistent with how
you feel, perform a Blood Glucose mode test to measure your glucose. If the problem continues, discard
the old sensor and insert a new sensor.
You should never reset your user settings when you are wearing a sensor. This will reset parameters that
•
may affect your system performance.
If you accept an incorrect transmitter ID when linking your Transmitter and Receiver, your glucose
•
readings will be incorrect.
Do
• NOT use the sensor delivery unit if the sterile package is open or damaged.
Important:
Once the code has been entered and you have hit the Set button, you will not be able to change the sensor •
code number. If you have entered the code incorrectly, you will have to replace the sensor and enter the
right sensor code. If you choose the wrong sensor code, you may get erroneous results from the sensor. The
code numbers MUST match to ensure accurate test results.
Do
• NOT remove or replace the transmitter from the sensor support mount while wearing a sensor. If
you notice that the transmitter is not properly attached, replace the sensor with a new sensor and then
reattach the transmitter.
Important Things to Remember About System Calibration
Caution: Always calibrate the system using only a finger-stick blood sample. Do NOT use alternate site
blood glucose measurements to calibrate the system. The receiver contains a built-in FreeStyle® Blood
Glucose Meter for performing calibration tests.
Important: Your blood glucose level must be between 60 and 300 mg/dL (3.3 and 16.7 mmol/L) to be able
to perform calibration tests. If your blood glucose level is changing rapidly, you may not be able to calibrate
the system. For example, during a meal or exercise, your glucose levels may vary rapidly. Try to time your
sensor insertion so that your calibration times do not coincide with your regular meal or exercise activities.
