Messages and Troubleshooting
The following three tables list the common (occur for both mainstream and sidestream), mainstream, and sidestream
messages that may appear on the M Series unit, possible causes, and the action(s) to take if the message indicates a
problem. You should become thoroughly familiar with this information before monitoring patients.
COMMON MESSAGES
Message/Symptom Possible Cause(s) Recommended Action(s)
----- (dashed lines in EtCO
2
field) After a defibrillation discharge, the numeric
value displays as “----” for approximately
10 seconds.
When the respiration rate is zero, the
numeric CO
2
value will display “---”. When
the respiration rate is greater than zero, the
actual CO
2
numeric value will be displayed.
None, normal operation.
----- (dashed lines at top of
capnogram waveform) Scale value setting incorrect. Measured
CO
2
higher than scale limits.
Adjust to higher scale setting using the
Zoom key.
CO2 COMM ERROR No communication from the EtCO
2
module
or sensor.
Turn M Series unit off, then on again to
reset.
If problem persists, return for service.
CO2 DEVICE NOT READY The zero operation cannot be initiated
because:
•
The sensor or module is still warming
up.
• No sensor or module is attached to the
unit.
Wait for sensor or module to warm up.
Attach sensor or module to the unit.
CO2 OUT OF RANGE (dashed
lines for CO
2
)
Calculated CO
2
value is greater than
100 mmHg.
If error persists, perform an adapter or
module zero
CO2 UNIT ERROR Defective EtCO

module or sensor. Turn M Series unit off, then on again to
reset.
If problem persists, contact Technical
Support.
INVALID CO2 DEVICE CAPNOSTAT 3 sensor or LoFlo Module is
not responding to the M Series unit. Turn M Series unit off, then on again to
reset.
Try another sensor/module.
If problem persists, contact Technical
Support.
WARM UP Mainstream sensor or LoFlo sidestream
module is warming up. This may take up to
5 minutes. Wait for sensor or module to warm up (max
5 minutes).
If message persists more than 5 minutes,
replace the sensor, or module.
ZERO DONE The mainstream sensor or adapter zero, or
the LoFlo module zero, is finished. No action required.
ZERO FAILED The zero operation did not complete
successfully. Clear occlusion, remove source of CO
2
, and
try zeroing again. If problem persists,
contact Technical Support.
