A Letter To LifeScan Customers:

 -- URGENT PRODUCT NOTIFICATION ABOUT ONE TOUCH(r) PROFILE(r) METERS --
If you use a ONE TOUCH(r) Profile(r) Blood Glucose Meter (intended for
use with ONE TOUCH(r) Brand Test Strips) to test your blood glucose,
recommend it to your patients, or distribute and sell it to customers,
please take a few moments to read this  important announcement.

Some ONE TOUCH Profile Meters May Develop Display Problems  The ONE
TOUCH Profile Meter has a display that presents test results and other
important information.

   The display is made up of a series of "segments" that
   are turned on and off in various combinations to form

    letters and numbers.

 Any meter's display, as it ages, may begin to show signs of failure.
This can cause certain letters or numbers to appear as incomplete. If
the meter's display begins to fail, there is a possibility that it will
present a test result or a calibration codethat could be misinterpreted
or is unrecognizable. It is therefore extremely important that you check
your display each time  you test your blood.
