Helpful Information (con’t)You • MUST successfully complete 4 calibration tests. You will calibrate at approximately 10, 12, 24 and
72 hours aer sensor insertion. If you do not complete calibration tests successfully in the allotted time
periods, your glucose readings will NOT be displayed and alarms will be inactive. e system may ask
you to perform additional calibrations between 2nd and 3rd calibrations depending on the sensor signal.
In such cases, you will be prompted with a message to do additional BG tests.
e receiver will beep (or vibrate) to prompt you to do a calibration. e receiver will display a blood •
drop icon and the message “Do BG Test.” e system will prompt you with alarm messages when
your calibrations are unsuccessful.
You will not have continuous monitoring until you have successfully completed the rst calibration (at •
least for the rst ten hours aer sensor insertion).
If you get a request for a calibration or expect additional calibration requests during a time when you do •
not want to be disturbed (e.g. sleep time), you can choose to wait to perform additional BG tests at a later
point in time. If you choose to wait and the allotted time window for calibration has expired, please note
that you will not get glucose results until you have performed a successful calibration. You can turn o the
System Alarms (or set to vibrate) if you do not want to be disturbed by frequent requests for calibration.
In order to silence the alarms that warn you when the allotted time window for a calibration has expired,
you must turn o the data loss alarms and all the four glucose alarms (Low Glucose, High Glucose,
Projected Low Glucose and Projected High Glucose).
When to calibrate the system?
You will calibrate the system at approximately 10, 12, 24 and 72 hours aer sensor insertion.
For example:
Insertion at night
If you insert the sensor at 9:00 pm on Day 1,
the rst calibration would be at 7:00 am on Day 2,
the second calibration would be at 9:00 am on Day 2,
the third calibration would be at 9:00 pm on Day 2,
the fourth calibration would be at 9:00 pm on Day 4.
Sensor removal would be at 9:00 pm on Day 6.
Although a typical calibration sequence will occur as shown, each calibration has to be performed in a
specic window of time.
1st calibration: Must be performed at approximately 10 hours aer a new sensor has been inserted. •
e rst calibration can be performed aer the 10 hours. Continuous glucose readings will NOT be
reported until the 1st calibration is performed successfully.
2nd calibration: Must be performed between 2 and 4 hours aer the 1st calibration or continuous •
glucose will not be reported. e 2nd calibration can be performed aer 4 hours; continuous glucose
reporting will resume aer completing the 2nd calibration successfully.
3rd calibration: Must be performed between 12 and 20 hours aer the 2nd calibration or continuous •
glucose will not be reported. e 3rd calibration can be performed aer 20 hours; continuous glucose
reporting will resume aer completing the 3rd calibration successfully.
4th calibration: Must be performed between 48 and 56 hours aer the third calibration or continuous •
glucose will not be reported. e fourth calibration can be performed aer 56 hours; continuous
glucose reporting will resume aer completing the 4th calibration successfully.
What happens in the example if the rst calibration does
not occur until 9 am on Day 2?
e 2 hour delay will add on to the second, third and fourth
calibration. Second calibration will now happen at 11 am on
day 2 and so on. However, sensor removal will still happen at
9 pm on Day 6.
