If this is displayed then turn the unit off, remove the mouthpiece
adapter, and expose to ambient air for 2 minutes before repeating
the test.
Note: If this warning appears again after following the above
procedure then turn off and leave the sensor exposed to ambient
air for a further 3 minutes. If the same message appears again then
this indicates possible contamination of the sensor with a solvent.
In this case remove all sources of solvent from the vicinity of the sensor
and expose to ambient air for 24 hours before switching on again.
