is guide has many Sections arranged in a logical sequence that will be useful

for rst-time use and every use thereaer. Most Sections begin with a purpose for

that Section, when to perform the steps in that Section, materials required to perform

the steps in that Section and important cautions, warnings and helpful information.

e rst page of each Section will be very useful when you are becoming familiar

with the system. Once you are familiar with the system and the general precautions,

you may nd yourself relying less on the rst pages of the individual Sections.

e remainder of each Section describes the steps for performing the tasks. e

steps are organised in a simple manner to allow you to see what to do based on

what you experience and based on where you are in that particular Section. It is

important that you go through the steps in the order that they have been presented.

Every Section also indicates if you have reached the end of the Section. If you nd

it dicult to use the guide or if you seem lost or confused, use the table of contents,

index, glossary and appendices to help you. e Table of Contents provides a list

of the Sections that you will nd in this guide and what each Section contains. e

Appendices contain useful information to which you may need to refer. e Glossary

provides a list of terms and their meanings. e Index is a tool you can use to quickly

nd terms and items that you seek.

Warnings, Cautions And Important Notes

Important Notes About System Performance

e following items describe situations that could lead to inaccurate or unreliable continuous glucose results.

Caution: 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. e 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.

Caution: During times of rapidly changing glucose levels, continuously reported interstitial glucose levels as

measured by the FreeStyle Navigator Sensor may not accurately reect blood glucose levels. When glucose

levels are falling rapidly, continuous glucose results from the FreeStyle Navigator Sensor may be higher than

blood glucose levels. Conversely when glucose levels are rising rapidly, continuous glucose results from the

FreeStyle Navigator Sensor may be lower than blood glucose levels. Under these circumstances use the built-

in FreeStyle Blood Glucose (BG) Meter to conduct nger-stick testing to check the continuous glucose results

from the FreeStyle Navigator Sensor.

Caution: Clean previously used transmitters and receivers according to the instructions in Section 14 prior

to using the FreeStyle Navigator system yourself.

Caution: If a FreeStyle Navigator system was previously used by another person, the system log should be

cleared using the “Erase History” command and the system settings should be returned to their defaults using

the “Reset User Settings” command. ese steps are important to ensure data integrity.

Caution: If the FreeStyle Navigator Receiver was previously used by another person, it may contain data

that is not your data. Make sure to only use data in the Statistics, Line Graph and Event History reports that

correspond to your actual sensor wear time.

Important Things to Remember About System Calibration

Caution: Always calibrate the system using a nger-stick blood sample. Do NOT use alternative site blood

glucose measurements to calibrate the system. e receiver contains a built-in FreeStyle Blood Glucose

Meter for performing calibration tests.

Important: Your blood glucose level must be between 60 and 400 mg/dL (3.3 and 22.2 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.

Important Things to Remember About System Calibration (cont.)

Important: In clinical trials, we observed that the sensor signal sometimes temporarily decreases from

the true value. is typically happens at night during sleep, and recovers rapidly when the user moves

or is awakened. However, in order to avoid being aected by this phenomenon the system should not be

calibrated when the wearer is asleep.

otherwise the battery life may not be accurately monitored.

Important:

• Analarmwillsoundandabatteryiconwillappearonthescreenwhenyourreceiverbatteriesare

to replace batteries before inserting your next sensor.

• Analarmwillsoundandamessagewillappearonthescreenwhenyourtransmitterbatteryisrunning

low. You have approximately 4 days of battery power remaining when this rst happens.

• Becauseyoumustinsertanewsensoraereachbatteryreplacement,youshouldreplacethebatteries

just before you insert a new sensor. For example, if you drop your receiver and the batteries fall out,

you will have to insert a new sensor.

• Aerinstallingthetransmitterorreceiverbatteries,allowacoupleofminutesforthesystemto

recognise the new batteries. You may then access the status of the battery life from the System menu

in your receiver (see Status Information in Section 11). If the batteries are new, the status screen will

show 75-100% as the remaining battery life.

•If your receiver batteries are low and you fail to replace them, they may run out without a

warning and the receiver will neither display your glucose levels nor sound alarms.

•etransmitter’sbatterylifeisestimatedtobeupto30days.
