Error Messages and Troubleshooting
Error Messages and Troubleshooting
The MyStar Extra® Blood Glucose Monitoring System has been
designed to work accurately under most usual conditions. On rare
occasions, the meter will display an error message instead of a
glucose result.
The meter is able to detect speci c problems, which may allow you
to determine the cause of the error without wasting valuable test
strips. When you are presented with an error message, check for
possible problems related to each message listed in this chapter.
Messages occurring while a test strip is inserted are displayed until
the test strip is removed or the meter automatically deactivates.
Messages occurring when no test strip is inserted are displayed
until the meter deactivates or you insert a strip.
CAUTION: In certain cases, the meter may return an error code
or provide an inaccurate result if it is being used near electrical
equipment, like a power generator or a computer monitor. If this
is the case, move the meter away from the source of electrical
interference.
CAUTION: If you get repeated error messages and are experiencing
symptoms of hypo or hyperglycemia, contact your healthcare
professional immediately as this may indicate low or high glucose.
If this error code persists on retesting, consult your healthcare
professional.
