Electromagnetic Interference and Your FreeStyle Navigator®

Continuous Glucose Monitoring System

Important Information about Electromagnetic Interference
e FreeStyle Navigator® Transmitter and Receiver communicate using radio frequency waves. e
FreeStyle Navigator system has been designed to be reliable and immune to common electromagnetic
interference so that it is not inuenced by such interference. However, under rare circumstances, if you
happen to be in an environment of strong electromagnetic radiation, there may be some interference.
Examples of possible sources of interference are: store doorways, store checkout counters, metal
detectors like those used in airport security systems or electronic surveillance devices, and radio
transmitting devices such as cellular phones, 2-way radio and cordless phones.
Interference may occur in the vicinity of equipment marked with symbol.
If such interference happens, it tends to be temporary. is makes it unlikely that you will experience
any noticeable dierence in the performance of the system. In the event of electromagnetic
interference, you may experience loss of communication between the receiver and transmitter, you
may see unrecognizable characters on the receiver display screen, or you may not see continuous
glucose results. e system is designed to alert you of these conditions through audio (beep or vibrate)
or visual (icons, unrecognizable characters on the screen or lack of glucose results) means.
If you observe a signicant change in your continuous glucose readings that you think is erroneous, or
if you feel the blood glucose measurement in the Blood Glucose mode is erroneous and you are close
to an electromagnetic interference source, move away from the source of interference and check to see
if the condition fades away. Always maintain a minimum separation distance from potential sources of
electromagnetic interference (see Tables 3 and 4 in this section for guidance).
Depending on your distance from the source of interference, the strength of the interfering signal,
and the relative orientation between you and the source of interference, you may or may not see or
experience these conditions. When in doubt, move away from any likely source of electromagnetic
interference. If you experience consistent interference from any source, contact the manufacturer or
dealer for that source and have a trained technician assess the situation. In addition, please report any
consistent interference issues to Abbott Diabetes Care Customer Care.
If you have a medical appointment that includes X-ray, MRI (Magnetic resonance Imaging), CT
(Computed Tomography) scan, or another type of exposure to radiation, keep your system and sensor
away from the area. Before exposure to such radiation, discard any sensor you are wearing and insert a
new sensor aer the radiation session. e eect of these types of radiation on the performance of the
system has not been evaluated.
