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.
No or poor signal on a channel
HighSymptoms: Flat or noisy airflow, effort, SpO2, ECG or EEG channel during a sleep study.
Root cause: Sensor / belt fault, a lead-wire or headbox connection fault, or the input amplifier.
Recording / data-card fault
MediumSymptoms: Study not saved, card not recognised, incomplete recording.
Root cause: Failing or incompatible data card, or the card slot.
Battery / power fault
MediumSymptoms: Study ends early on batteries, will not power on.
Root cause: Depleted / aged batteries or a contact fault.
Bluetooth / download fault
LowSymptoms: Data will not transfer to the Sleepware software.
Root cause: Bluetooth pairing, cable, or driver.

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: Poor signal on a channel
- Fit fresh sensors / belts and confirm placement.
- Reseat the lead wires at the headbox / device.
- Swap in a known-good sensor / cable for that channel.
- Run the device's signal / impedance check.
- Refer the headbox if a channel is still dead with good sensors.
Symptom: Recording / card fault
- Try a different, compatible data card.
- Reformat the card in the device.
- Inspect the card slot.
- Record a short test study and download it.
- Replace the card.
