Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
CO2 reading drift / needs calibration
HighSymptoms: EtCO2 does not match a reference, slow response, baseline offset.
Root cause: CO2 sensor aging, or the user CO2 calibration not performed.
No CO2 waveform
MediumSymptoms: Flat trace, "no breath" alert with the patient breathing.
Root cause: Fouled or wet mainstream airway adapter / sidestream line, or a sensor cable fault.
Short battery run time
MediumSymptoms: Unit powers off quickly, will not hold charge.
Root cause: Aged rechargeable pack; disposable AA pack depleted.
SpO2 no signal (if fitted)
LowSymptoms: No saturation value with a good sensor site.
Root cause: SpO2 sensor or cable fault.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: CO2 value looks wrong
- Perform the user CO2 calibration.
- Verify against a known CO2 reference.
- Fit a fresh airway adapter / sample line and clear any moisture.
- Replace the CO2 sensor if it will not calibrate or hold zero.
- Re-verify before returning to use.
Symptom: No waveform
- Fit a clean, dry mainstream adapter or a fresh sidestream line and water trap.
- Check the sensor cable for damage.
- Confirm the sampling pump runs (sidestream).
- Replace the sensor if there is still no signal.
- Confirm a normal capnogram.
