Error and other messages
The OneTouchSelect Plus Flex™ Meter displays messages
when there are problems with the test strip, with the
meter or when your glucose levels are above 600mg/dL
or below 20mg/dL. Improper use may cause an inaccurate
result without producing an error message.
NOTE: If the meter is on but does not operate (locks-up),
contact Customer Service. Contact LifeScan Customer
Service at: [e-mail].
What it means
You may have a very
low blood glucose level
(severe hypoglycaemia),
below 20mg/dL.
NOTE: When your glucose result is below 20mg/dL, both
the LO and the Range Indicator Arrow will flash on the
meter screen.
What to do
This may require immediate treatment. Although this
message could be due to a test error, it is safer to treat
first and then do another test. Always treat according to
your healthcare professional’s recommendations.
