None CO2 is warming up The mainstream sensor is
going through the warm-up
cycle.
– Wait for the mainstream
sensor to warm up. During
the warm-up, the accuracy is
reduced.
– If the message persists
longer than 15 min after the
sensor has warmed up, and
the ambient temperature is
above 10
o
C, contact Dräger

– The M540 has detected
that the used
mainstream sensor is
not compatible with the
selected sensor type
setting
(reusable/disposable)
– Secretions in the
adaptor
– The sensor has a zero

concentration
– Use the airway adaptor type
the system is configured for
or adjust the airway adapter
setting (see page 295).
– If the message persists,
clean or replace the airway
adaptor.
– If the message persists even
though the correct airway
adaptor type is selected and
the airway adaptor is clean,
zero the sensor.
– If the message still persists,
the inspiratory CO
2 value
might not be accurate. Check
the patient and ventilation.
Priority Message Problem Solution
NOTE
You cannot zero the sensor
when this message is
displayed and the ambient
temperature is above 10
o
C
(50
o
F).
When the ambient
temperature is below 10
o
C
(50
o
F), the message can
persist longer than 15
minutes. In this case, it is
possible to zero the sensor
after the message has been
displayed for at least 10
minutes.
