Note: Test results taken prior to the time and date being set will
not have a time and date associated with them on the meter.
You can manually add these readings to the App to include them
in your statistics. Test results without a set time and date will be
displayed on your meter with "--:--" and "--/--" in place of the time
and date.
Important Pairing Information:
The Bluetooth® feature on your meter sends test results to
your supported device. Data synced from the meter cannot
be deleted from the App.
To prevent test results from other people being sent to your
supported device:
[1] Do not let another person test their blood glucose with
your meter. This meter is for single patient use only.
[2] Do not pair or sync a meter used by another person with
your supported device. If you pair with another person's meter,
the data from each meter will be combined in the App and
will cause your logbook history and statistics to be incorrect.
