Fault
All probes return no echo on startup
Fix
RFM423 channel rework; element-by-element calibration. Echo restored across linear, convex and 4D probes.
Service narrative
Persistent imaging anomaly across multiple probes. Bench-isolated to the RFM beamformer module. Replaced the failing front-end ICs, recalibrated the full channel map, and reverified each probe class on a live Voluson E10 chassis for 48 hours before sign-off.
