Huntleigh Sonicaid FM800
Huntleigh · Model Sonicaid FM800
Antepartum CTG analysis- Provides and objective, numerical and consistent assessment of the CTG. Clinicians can rely on the worlds largest database of collective experience to support their own visual assessment. Intrapartum trend- Measures changes over time in the FHR. For use during the 1st stage of labor, clinicians are quickly alerted to changes in short term variability, baseline rate and deceleration size.
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 FHR signal or high % signal loss
HighSymptoms: No fetal heart rate displayed, frequent dropouts, poor trace.
Root cause: Ultrasound transducer crystal degraded or cracked, insufficient gel / poor placement, or a damaged transducer cable.
Toco not tracking contractions
MediumSymptoms: Uterine activity flat or noisy, will not zero.
Root cause: Toco transducer strain gauge, belt tension, or zero-reference fault.
No trace printed
MediumSymptoms: Monitor runs but no paper output.
Root cause: Out of paper, paper tray not fully pushed in, or a thermal print-head fault.
"FM800 failure" system error
HighSymptoms: Error message, monitoring stops.
Root cause: Internal fault - the manual directs the user to stop, note the message and return the unit to Huntleigh.
Oximetry no signal
LowSymptoms: MSpO2 shows no value when the sensor is connected.
Root cause: Oximetry module not connected to the FM800, or a sensor fault.

Error Codes
Extracted directly from this unit's own service manual.
FM800 failureStop monitoring. Remove transducers from mother. If there is an error message, make an exact note of what it says. Return FM800 to Huntleigh Healthcare Ltd or their local representative.
Poor print qualityMake sure you have the right paper loaded. FM800 uses Sonicaid paper (part number 8400-8003). Make sure the paper tray is fully pushed in. Try printing again. If there is no improvement, clean the print head. See Section 14.4.
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: No FHR / high signal loss
- Confirm the FM800 is on and the FHR transducer is connected.
- Re-apply gel and check transducer placement.
- Swap in a known-good ultrasound transducer.
- Consider switching from ultrasound to FECG if appropriate.
- Replace the transducer if a good one fixes it.
Symptom: No trace printed
- Confirm the Print button was pressed.
- Check there is paper in the tray and the tray is fully pushed in.
- Clear any paper jam.
- Clean or replace the thermal print head.
- Print a test trace to confirm.
