Key tips
- ·Never bypass a radiation interlock to "just get the image" - this is one of the few true zero-tolerance rules in BMET work.
- ·Trend image-quality phantom results over time - drift shows up before an outright failure does.
- ·Portable/mobile units take real physical abuse from transport - check wheel locks and cable strain reliefs more often than fixed units.
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.
Poor or lost FHR trace
HighSymptoms: Fetal heart rate drops out, doubles / halves, or is noisy; hard to keep a trace.
Root cause: Worn ultrasound (Doppler) transducer, low gel, or a transducer-cable fault.
Toco / contraction channel fault
MediumSymptoms: Contraction trace flat, drifting, or will not zero.
Root cause: Worn toco transducer or its cable.
Printer / recorder fault
MediumSymptoms: No trace on paper, faint print, paper jam, wrong speed.
Root cause: Thermal print head, paper handling, or the paper-speed setting.
NIBP / SpO2 (maternal) fault
LowSymptoms: Maternal NIBP or SpO2 drops or is implausible.
Root cause: Cuff / hose or sensor, or the parameter module.
Display / central-link fault
LowSymptoms: Blank display, not shown on the OB surveillance system.
Root cause: Display or the network / surveillance link.

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.
- ·Daily QC per modality: image-quality phantom test
- ·Tube and detector inspection
- ·Annual state-required radiation safety survey
- ·Vendor-scheduled preventive maintenance
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: Losing the fetal heart rate trace
- Apply fresh gel and reposition the ultrasound transducer for the strongest tone.
- Swap in a known-good ultrasound transducer.
- Flex the transducer cable while watching for dropout.
- Confirm the FHR against a handheld Doppler.
- Replace the transducer if a good one holds the trace.
Symptom: No or poor paper trace
- Confirm the correct paper is loaded the right way up.
- Clean the thermal print head.
- Check the paper-speed setting (1 vs 3 cm/min).
- Print a test pattern.
- Replace the print head if output stays faint.
