Dear Valued Customer,

It has come to our attention that FreeStyle Navigator transmitters could potentially exhibit a fracture on the plastic housing near the battery compartment. Should this occur, there is a possibility that moisture may enter into the transmitter.

If moisture has not entered the transmitter, the transmitter will continue to function normally even with a fracture in the plastic housing. You may continue to use your FreeStyle Navigator under normal conditions such as showering.

However, if moisture enters the transmitter, it may cause the transmitter and the receiver to lose connection, interrupting continuous glucose results. Although unlikely, moisture entering the transmitter has the potential to generate inaccurate results only with the continuous glucose readings.

This issue does not affect the built-in blood glucose meter. Results that are generated from the built-in meter are accurate.

If you observe moisture in the FreeStyle Navigator transmitter now or at any time, discontinue use of the transmitter and call Abbott Diabetes Care Customer Care at: 1-800-418-6427.

If you encounter a loss of connection or if you believe your results are not reliable or are inconsistent with how you feel, consult your User's Guide for troubleshooting guidelines. If the issue is not resolved, call Abbott Diabetes Care Customer Care at: 1-800-418-6427. Abbott Diabetes Care will replace any defective product at no cost to you.

We regret any inconvenience this issue may cause and we thank you for your continued support of Abbott Diabetes Care and the FreeStyle Navigator system.
