Key tips
- ·Electrode impedance drives data quality more than almost any other single factor - check it before assuming an amplifier fault.
- ·Pre-case verification of intraoperative monitoring equipment isn't optional - a mid-case failure has direct surgical-decision consequences.
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.
Excessive noise / poor signal on a channel
HighSymptoms: 50/60 Hz or broadband noise, flat or noisy trace on one or more channels, high electrode impedance.
Root cause: Electrode / lead-wire fault, a headbox / amplifier input fault, or a grounding / environment problem.
Stimulator output fault
MediumSymptoms: No or weak electrical stimulation, no patient response, stimulator-error message.
Root cause: Stimulator probe / bar-electrode fault, its cable, or the stimulator output stage.
Headbox / amplifier fault
MediumSymptoms: One or more channels dead or saturated on all inputs, calibration fails.
Root cause: Headbox / amplifier module fault.
Acquisition PC / software fault
MediumSymptoms: Acquisition hangs, studies will not save or export, license / dongle error.
Root cause: Workstation PC, software, or the license key.
Audio / stim-artefact / trigger fault
LowSymptoms: No audio monitor, trigger not registering (evoked potentials).
Root cause: Speaker / audio board or the trigger input.

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.
- ·Electrode / lead impedance check
- ·Amplifier calibration
- ·Annual electrical safety test
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: Noisy channel or poor signal
- Check electrode impedances and re-prep the skin.
- Swap the lead wires and try a different headbox input.
- Move away from mains-powered equipment and confirm the ground / reference.
- Run the amplifier calibration / impedance check.
- Replace the lead set or headbox as isolated.
Symptom: Stimulator gives no response
- Confirm the stimulator settings and that intensity ramps.
- Swap the stimulator probe and cable.
- Test on a saline / test load per the manual.
- Check the stimulator output on a second channel.
- Refer the stimulator output stage if a good probe still gives nothing.
