Questions researchers usually ask

How complex is the initial setup and calibration?

The system is designed for research environments where setup time directly impacts study feasibility. Standard EEG cap placement and impedance checking typically requires 15-20 minutes with trained personnel. Our application specialists provide hands-on training at your facility, and most research groups achieve independent operation within the first week. The software guides you through calibration procedures with clear feedback at each stage.

Can the system scale as our research program grows?
