Key tips
- ·When no category-specific guidance fits, default to the manufacturer's own service manual and the general troubleshooting method in the Engineer's Guide.
- ·Run an incoming and annual electrical safety test regardless of how niche the device is.
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.
Frequent false apnea / bradycardia alarms
HighSymptoms: Alarms with the infant breathing normally, noisy respiration trace.
Root cause: Loose or poorly placed respiration belt/electrodes, motion artefact, or a worn belt sensor.
No respiration or heart-rate signal
HighSymptoms: Flat trace, "lead off", monitor will not detect breaths.
Root cause: Belt sensor or patient-cable fault, or electrodes dried out.
Will not power on / short battery life
MediumSymptoms: Dead unit or shuts down off mains.
Root cause: Depleted or aged battery, or a charger fault.
Alarm not audible
MediumSymptoms: Visual alarm only, no or quiet audible alarm.
Root cause: Speaker or alarm-volume fault - a safety-critical failure.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Follow the manufacturer's PM schedule
- ·Perform incoming and annual electrical safety testing per facility biomedical program
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: False apnea/brady alarms
- Reposition the respiration belt snugly at the correct level and check electrode contact.
- Replace dried electrodes and inspect the belt sensor for wear.
- Reduce motion / handling during monitoring.
- Swap in a known-good belt and cable.
- Confirm a clean respiration and ECG trace before returning to use.
Symptom: No signal
- Check the belt sensor and patient cable for damage.
- Reseat all connectors.
- Substitute a known-good belt/cable.
- Run the monitor's self-test.
- Verify the audible alarm works at the set volume.
