Key tips
- ·Never defeat or bypass a return-electrode monitoring (REM) alarm to finish a case - it's a direct burn risk.
- ·Verify OR table battery backup - a table that loses power mid-procedure is a real, documented incident type.
- ·Track surgical light lamp-hours rather than waiting for failure - a sudden failure mid-case is avoidable.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Electrosurgical electrode wear
MediumSymptoms: Poor cut/coag, sparking, low power.
Root cause: Burned/eroded blade or pencil.
Return electrode / pad fault
HighSymptoms: Pad alarm, no activation.
Root cause: Poor contact or expired pad.
Reprocessing / sterilization failure
MediumSymptoms: Residue, bioburden, discoloration.
Root cause: Inadequate cleaning cycle or damaged tray.
Foot switch failure
MediumSymptoms: Unintended or no activation.
Root cause: Fluid ingress / worn switch.

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.
- ·Pre-case functional check
- ·Electrosurgical return-electrode cable inspection
- ·Table hydraulic / mechanical inspection
- ·Annual electrical safety test and full PM
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Electrosurgical electrode wear
- Confirm the presentation - typically poor cut/coag, sparking, low power - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: burned/eroded blade or pencil.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the electrosurgical pencil & electrode per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
Symptom: Return electrode / pad fault
- Confirm the presentation - typically pad alarm, no activation - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: poor contact or expired pad.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the return electrode (patient plate) per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
