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.
Will not reach or hold set cuff pressure
HighSymptoms: Pressure droops during a case, will not inflate to setpoint, leak alarm.
Root cause: Internal pump / compressor wear, a solenoid-valve fault, or a leak in the tubing / cuff / connectors.
Pressure inaccuracy / calibration drift
HighSymptoms: Displayed pressure differs from an independent gauge - patient-safety critical.
Root cause: Pressure-transducer drift or a calibration fault.
Dual-channel / bilateral fault
MediumSymptoms: One channel will not regulate independently, cross-talk between channels.
Root cause: Channel solenoid / transducer or a manifold fault.
Alarm / timer fault
MediumSymptoms: Inflation-time alarm not sounding, timer wrong.
Root cause: Alarm / timer board fault - a safety function.
Tubing / connector / cuff fault
MediumSymptoms: Leak at the connector, cuff will not hold.
Root cause: Worn tubing, connectors, or a damaged cuff.

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 or low RF output / high-impedance cut-out
- Confirm good electrode-tissue contact and an adequately wetted field.
- Inspect the handpiece / instrument and its cable for damage; substitute a known-good one.
- Check the split dispersive (return) pad is well applied over well-perfused muscle with a sound cable.
- Verify output into a resistive test load with an electrosurgical analyser.
- Replace the RF output board and recalibrate on a non-conductive surface if output is confirmed absent (anti-static handling).
Symptom: Return-electrode (REM / NESSY / CQM) contact-quality alarm
- Re-apply a fresh split dispersive pad with full skin contact.
- Check the pad cable and its connector.
- Try a known-good pad.
- Run the contact-quality-monitor calibration with a good pad fitted.
- Refer the CQM circuit if it still alarms.
Symptom: Output will not activate from the footswitch or handswitch
- Test the other activation method to isolate the pedal from the handpiece.
- Inspect the footswitch and its cable / connector for damage or moisture.
- Check the handswitch leads on the handpiece.
- Substitute a known-good footswitch.
- Refer the activation input board if both methods fail.
Symptom: Fails calibration / output drifts after a repair
- Verify cut and coag output at several settings into a test load with an analyser.
- Verify the REM / CQM circuit against its spec.
- Recalibrate per the service manual on a non-conductive bench with anti-static precautions.
- Check the cooling fan and thermal path.
- Re-verify all outputs and the REM alarm before returning to service.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Tourniquet cuff flange may become detached from the bladder. If leak occurs during the procedure, there may be risk of hemorrhage, resulting in blood loss greater than expected. Other serious risks include cerebral hypotension and cardiovascular collapse and arrest, risking stroke or death. Specific to IVRA, patient toxicity may also occur due to rapid systemic absorption of anesthetics.
- RECALL
Three complaints have been reported indicating that the product inside the package did not match the label description. The units had quick connectors instead of luer lock connectors as stated in the label description.
- RECALL
This recall is related to the Electi-cord recall. There is a risk when excessive force is applied to the plugs, a fracture can develop on the prongs inside the molded section of the plug. Over time the fracture may lead to arcing inside of the molded sction of the plug and a build up of heat which can cause charring, electric shock or fire. To this date there have been zero complaint for this fa
