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.
Ultrasoustic output drops to zero or displays error during treatment
HighSymptoms: Therapy head produces no ultrasound output or intermittent output; display may show reduced power or fault indicator; patient reports no sensation.
Root cause: Piezoelectric crystal degradation or internal microfracture within the applicator; waveguide seal failure allowing moisture ingress; mainboard ultrasound driver IC failure.
Electrical stimulation channel produces no output or intermittent output
MediumSymptoms: Stimulation channel fails to deliver current; waveform selection has no effect; patient reports tingling only on one channel.
Root cause: Output relay contact wear or failure; stimulation driver transistor degradation; electrode cable shield break or connector pin corrosion.
Device fails to power on or shuts down unexpectedly
HighSymptoms: Power button unresponsive; unit displays blank screen or immediate shutdown; no LED indicators.
Root cause: Internal fuse blowout (line voltage surge); AC power inlet terminal block loose or damaged; mainboard power supply capacitor failure; battery pack (if equipped) cell degradation.
Waveform selection does not change output characteristics
MediumSymptoms: Device remains in default mode regardless of user selection; menu navigation appears functional but settings have no effect.
Root cause: Software logic fault in firmware; waveform selection switch/contact matrix failure; mainboard MCU communication error with stimulation DSP.
Thermal overload protection activates prematurely
LowSymptoms: Device shuts down ultrasound output after short duration; display shows thermal warning; applicator feels warm but not excessively hot.
Root cause: Ultrasound power sensor drift or calibration loss; airflow obstruction over cooling vents; applicator contact surface degradation affecting heat transfer.

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: No ultrasound output, device powers on normally
- Visually inspect applicator cable and connector for damage or loose seating; verify 5 cm² applicator is properly attached to therapy head.
- Connect a known-working applicator to isolate whether fault lies in handpiece cable or mainboard driver.
- If output restored with known-good applicator, replace the original applicator as consumable wear item. If no output with known-good applicator, suspect mainboard ultrasound driver IC or waveguide seal failure.
Symptom: One stimulation channel produces no output, other channel functional
- Swap stimulation electrode cables between channels at the rear panel; if fault follows cable, replace the cable assembly.
- Inspect the relay contacts on the affected channel for pitting or carbon tracking; clean with appropriate contact cleaner if accessible.
- If relay contacts are intact and fault persists, replace the stimulation output relay assembly for the non-functioning channel.
