GE Corometrics FCB 400 Safelinc FSE (Fetal Spiral Electrode) A leg plate fastens to an expectant mother’s skin and interconnects electrodes at the fetal scale with an external heart rate monitor. The leg plate also senses voltage at the maternal skin to enable elimination of the maternal heartbeat from the output data.
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.
Image dropout / dead element lines (or weak FHR / toco signal)
HighSymptoms: Weak or intermittent fetal heart-rate signal, high % signal loss, or toco not tracking.
Root cause: Failed piezoelectric elements or (fetal) a degraded crystal.
Intermittent signal with cable flex
HighSymptoms: Image / signal drops or is noisy when the cable or strain relief is moved.
Root cause: Broken conductors in the transducer cable or at the connector.
Acoustic lens / membrane / housing damage
MediumSymptoms: Haze, artefacts, reduced penetration, a visible cut or bubble, cracked housing.
Root cause: Lens delamination or a puncture; drop damage.
Connector pin damage / not recognised
MediumSymptoms: System does not detect the probe or shows the wrong probe; bent or corroded pins.
Root cause: Damaged connector pins or a wet / dirty connector.

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: Dropout / dead lines / weak signal
- Re-apply gel and check placement; confirm the belt tension.
- Wipe off all gel, clean the face and re-gel.
- Try the probe on a second compatible system, and a known-good probe on this system.
- Inspect the face / lens for cuts or delamination.
- If the probe is confirmed faulty, return it for repair - do not open the housing.
Symptom: Signal drops when the cable is moved
- Flex the cable along its length and at both ends.
- Inspect the connector pins and the cable jacket.
- Confirm the connector is dry and fully latched.
- Return the probe for repair if the fault tracks the cable.
- Electrical-safety-test after any repair.
