Power
The USB port included on the headset is strictly for charging use. Attempting to extend battery life by connecting power to the device while on will cause the device to enter standby mode. While charging, the charging LED will be RED. After the headset has fully charged the charging led will turn GREEN.
Electrodes
The EPOC electrodes are modular allowing for easy replacement for alternative or replacement sensor modules. While the device is set to initially start
