Select biofeedback or polygraph first, then match your sensor, operating system and connection. Windows and Mac desktop installers require compatible real hardware. Supported mobile/Quest versions may offer clearly labeled Demo Signals. Downloading an app does not guarantee that every sensor works with it.
Charge or power the device. Install the official application, use the credentials provided, and grant only permissions required for your chosen function. Connect by the documented USB, OTG or Bluetooth route. Check signal quality and changing live values before starting. Never share passwords or patient records in a sales inquiry.
Choose a suitable training screen, follow its instructions and check the connection indicator. The full software guide explains orientation, setup, recording and review. If installation, login or sensor connection fails, record the application version and error message and contact sales@biosignals.co.il without sensitive records.
