Before fitting your headset please add primer fluid from the sensor pack onto each of the five sensors and both references. Turn on the headset, ensuring the white LED on the front lights and connect it via BLE or to a USB dongle prior to fitting onto the head.
Gently slide the headset onto the head. The reference sensors, which are on the black arm, should make contact with the skin behind the ear. If necessary, gently bend the reference sensor arm so that the sensors make contact with the skin. The frontal sensors should be positioned about three finger widths above the eyebrows.
