The meter was unable to pair with a
mobile device.
Retry the pairing.
The batteries are almost out of power.
Change the batteries now. If the symbol
reappears after the batteries have been
replaced, remove the batteries again,
press and hold either meter button for
at least 2 seconds, then reinsert the
batteries.
(The error code and Err will
alternate on the display.)
The test strip may be damaged, not
properly inserted, or was previously
used.
Remove and reinsert the test strip, or
replace it if damaged or previously
used.
(The error code and Err will
alternate on the display.)
A meter or test strip error has
occurred.
This error message could appear if the
cap on the test strip container was not
closed tightly. The test strips may have
been damaged due to improper
storage or handling.
Never make therapy decisions
based on an error message.
Repeat the blood glucose test. If a
second E‑3 error message appears,
perform a control test with the control
solution and a new test strip. See the
Performing a Control Test section in the
chapter Control Tests. If you continue
to receive an E‑3 error message, use
an alternate method for testing your
blood glucose, such as a back‑up
meter and test strip. If the alternate
method gives an extremely high blood
glucose result, or if an alternate
method is not available, contact your
healthcare professional
immediately.
In rare cases, an E‑3 error message
may indicate that your blood glucose is
extremely high and above the system’s
measuring range. See the Unusual
Blood Glucose Results section in the
chapter Blood Glucose Tests for
other possible causes of the error
message.
