Headset Control Unit (HCU)

Headset Control Unit (HCU)
 
The Headset control Unit or HCU is the brain behind the COGNISION™ Headset System.  This handheld, battery-powered device is held by the test subject while the EEG/ERP test is being performed.
 
The HCU performs three primary functions:
  • initiates the EEG/ERP test
  • displays status and test information
  • captures subject responses using the action buttons
 
NOTE:  The HCU contains a 3.7V rechargeable LiPoly battery.  This battery is not field replaceable.  If the device has difficulty charging, or maintaining a charge, contact customer service to request product servicing.
