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.
Gas / SpO2 readings drift or need calibration
HighSymptoms: Agent, CO2, N2O, O2 or SpO2 values off vs a reference, calibration prompts.
Root cause: Sensor aging, a missed calibration, or the wrong calibration gas.
Module / pod not recognised by the host
MediumSymptoms: Host monitor does not display the module or pod.
Root cause: Docking / pod connector or cable fault.
Water trap full / sample-line occlusion
MediumSymptoms: Occlusion or water-trap alarm, no or low sample flow, flat waveforms.
Root cause: Full or expired water trap, or a blocked / kinked sample line.
Cable / connector wear
LowSymptoms: Intermittent signal with cable movement.
Root cause: Worn patient cable.

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: Readings drift
- Fit a fresh water trap and sample line.
- Run the module's calibration with the correct calibration gas.
- Calibrate or replace the O2 sensor.
- Let the module warm up fully.
- Verify against a reference gas mix.
Symptom: Module / pod not recognised
- Reseat the module / pod at the host or rack.
- Inspect the docking connector for bent pins.
- Try it in another host or slot.
- Try a known-good module in this slot.
- Refer the module or the host slot as isolated.
