Regulate anesthetic drug use. Decreases the incidence of post-operative side effects such as nausea and vomiting. Reduce length of stay in the PACU (recovery room). Prevents intraoperative awareness. Greater awareness of patient-specific reaction to anesthesia and sedation. BISx power link works with a range of sensors.
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.
EEG / depth-of-anaesthesia signal poor
HighSymptoms: High SQI / EMG, noisy or flat EEG, BIS / index value unreliable or absent.
Root cause: Sensor contact / expiry, the patient interface cable (PIC), or a DSC / module fault.
Module not recognised by the host
MediumSymptoms: Host monitor does not display the module.
Root cause: Docking / rack connector or cable fault.
Cable / sensor wear
MediumSymptoms: Intermittent signal with cable movement.
Root cause: Worn patient / sensor cable.

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: Poor EEG / index signal
- Check the sensor is within date and fully adhered.
- Swap in a known-good cable / sensor.
- Reseat the module at the host / rack.
- Dock the module on a different host to isolate module vs host.
- Replace the cable or refer the module if the fault stays with it.
Symptom: Module not recognised
- Reseat the module at the host or rack.
- Inspect the docking connector for bent pins.
- Try it in another host or slot.
- Try a known-good module in this slot.
- Refer the module or host slot as isolated.
