Easy-to-use software applications for spike and seizure, burst suppression, sleep, mapping, remote monitoring, remote control, central monitor and trends. Impedance checking capabilities. Glow-in-the-dark overlays. 9 auxiliary pairs (AC or DC). Integrated SpO2. High quality data. Rugged headbox design with quick disconnect. VLink/HL7 compatible. Support Connect compatible. Sleep auxiliary input box.
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.
Noisy / high-impedance channels
HighSymptoms: Mains hum, drift or flat channels, persistently high electrode impedance, poor recording quality.
Root cause: Electrode / lead-wire wear, the electrode box (headbox) inputs, or poor skin prep / environment.
Headbox / amplifier fault
MediumSymptoms: A block of channels dead or saturated regardless of electrode, calibration / bio-cal fails.
Root cause: Headbox amplifier or its cable to the acquisition unit.
Amplifier-to-PC link / acquisition fault
MediumSymptoms: Recording drops, amplifier not detected, data gaps.
Root cause: USB / fibre / network link or a driver.
Photic stimulator / video / audio fault (diagnostic EEG/PSG)
LowSymptoms: Photic strobe not firing, no synchronised video, no audio.
Root cause: Photic lamp / trigger, the video camera, or the audio path.
PSG sensor fault (airflow / effort / SpO2 / limb)
LowSymptoms: A PSG channel (thermistor, pressure, RIP belt, SpO2, PLM) flat or noisy.
Root cause: Worn PSG sensor or its cable.

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 or high-impedance channels
- Check and re-prep electrode sites; confirm impedances are balanced and low.
- Swap the affected leads and try different headbox inputs.
- Run the bio-calibration / calibration signal.
- Address mains interference (route cables, check the ground).
- Replace the lead set or headbox as isolated.
Symptom: Amplifier not detected / recording drops
- Reseat the amplifier-to-PC link at both ends.
- Restart the acquisition software and amplifier.
- Try a different port / cable.
- Update the driver / firmware if indicated.
- Replace the link cable or refer the amplifier.
