A maintenance message requires your
immediate attention. The meter may stop
working temporarily. Some examples:
•
The batteries are empty.
•
The test strip has expired.
•
The meter may detect a problem when
performing a self-check.
Almost always you can fix the problem by
following the instruction in the maintenance
message. You can insert new batteries or start
the test again with a new test strip. Or the
meter often fixes a problem itself when you
power it off and on again.
