Important Things to Know About Getting Reliable Results

Warning: 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 then 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.
Caution: 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 over-bandage or the sensor support mount is coming loose, discard the old sensor and
insert a new sensor.
Now that you are ready to insert a sensor, here are a few helpful tips.
• Reconnect your transmitter and receiver BEFORE inserting a new sensor.
• BEFORE inserting a new sensor, programme into the receiver that the old sensor has been removed.
• Make sure there are no messages or icons related to low battery conditions on the receiver BEFORE
inserting a sensor.
• When attaching the transmitter, you may not always hear a click. Place the transmitter about halfway
over the sensor support mount and slide the transmitter back and forth to make sure it moves freely
before you attach it. You will feel a click as you slide it into place.
• After attaching the transmitter to a new sensor, allow the system a few minutes to recognise a new
sensor. Reconnect the receiver and transmitter to make sure they are communicating.
• When responding to messages about sensor insertion and sensor removal, choose the appropriate
answer ('Yes' or 'No').
• Do NOT use the Link/Unlink feature unless you have received a new transmitter or receiver from the
manufacturer. To establish communication between them, ALWAYS use the 'Reconnect' feature.
{Note: Link is NOT the same as Reconnect}
• Avoid errors and messages related to calibration by following a few simple guidelines:
• Do NOT calibrate if your blood glucose is higher than 400 mg/dL (22.2 mmol/L) or lower
than 60 mg/dL (3.3 mmol/L).
• If you have just exercised, eaten or taken insulin, your glucose levels may be changing rapidly. Allow
about an hour for the glucose levels to reach a relatively steady state before calibrating.
• The system automatically detects conditions that may not be suitable for calibration. It may delay
calibration requests in such instances. Wait for the system to prompt you and LOOK for the
icon on the screen.
• It is normal during typical usage to get multiple messages about calibrations (e.g. "Cal Failed"). The
system automatically evaluates conditions for calibration and displays appropriate messages if those
conditions are not met or if the calibrations fail. This helps maintain system accuracy. When you get
these messages, simply follow the prompts on the screen or guidelines in the User Guide. If you get too
many messages, please call Customer Care.
• Do NOT change batteries during a sensor wear. Changing the batteries resets the system and will force
you to remove the sensor.
If you need assistance, please call Customer Care.
