Each time you turn on the OneTouch

Meter either by inserting a test strip or
pressing the button, all segments of the
display will appear briefly. This tells you that
the system is performing several self-checks to
confirm that the meter is working properly.
To check that all display segments are working, with the meter off, press the
button and immediately hold the button down.
CAUTION: Matching the code on the meter and the code on the test
strip vial is essential to obtain accurate results. Each time you test,
check to make sure the code numbers match.
