Helpful Information

You

•

MUST successfully complete 4 calibration tests. You will calibrate at approximately 10, 12, 24 and

72 hours after 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. The 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.
The receiver will beep (or vibrate) to prompt you to do a calibration. The receiver will display a blood

and the message “Do BG Test.” The system will prompt you with alarm messages when

your calibrations are unsuccessful.
You will not have continuous monitoring until you have successfully completed the first calibration (at

•

least for the first ten hours after 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 off 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 off 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 after sensor insertion.
For example:

Insertion at night

If you insert the sensor at 9:00 pm on Day 1,
the first 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

specific window of time.

1st calibration: Must be performed at approximately 10 hours after a new sensor has been inserted.

•

The first calibration can be performed after 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 after the 1st calibration or continuous

•

glucose will not be reported. The 2nd calibration can be performed after 4 hours; continuous glucose

reporting will resume after completing the 2nd calibration successfully.
3rd calibration: Must be performed between 12 and 20 hours after the 2nd calibration or continuous

•

glucose will not be reported. The 3rd calibration can be performed after 20 hours; continuous glucose

reporting will resume after completing the 3rd calibration successfully.
4th calibration: Must be performed between 48 and 56 hours after the third calibration or continuous

•

glucose will not be reported. The fourth calibration can be performed after 56 hours; continuous

glucose reporting will resume after completing the 4th calibration successfully.

What happens in the example if the first calibration does

not occur until 9 am on Day 2?

The 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.
