Error Messages

prevent inaccurate results. If the meter detects a
malfunction, it displays the “Err” message and an
appropriate symbol.
Do not make treatment decisions based on an error
message.
The code key is faulty, or the
code key was removed while
the meter was on. Turn meter
OFF and re-insert code key. If
this error display still appears,
contact Roche Diagnostics.
