EMOTIV EPOC USER MANUAL | BRAIN COMPUTER INTERFACE TECHNOLOGY
One or more sensors remain black or red for every fitting and user
Check that the sensor is properly located in the socket. It should click firmly in place, the
finger tabs should be aligned along the axis of the arm and it should not freely rotate in the
socket.
Check that the sensor is sufficiently damp for operation
Check that the sensor is applying gentle but positive pressure to your head in this location.
When pressed, it should not move inwards. You may find that slightly relocating the
neuroheadset settles the sensors into a better location
Remove the neuroheadset and gently press the felt pad into the sensor. It should protrude
by no more than 2mm. It should also feel damp and be free of obstructions.
Remove the sensor and inspect it. The sensor should have a felt pad on the front side and
a domed gold-plated metal plate which is visible from the rear side. The metal plate should
be clean and free of obstructions at least across the central third of the domed section in
order to make proper contact when inserted.
Check the socket. Make sure the gold contact plate is clean and there is nothing trapped in
the socket which could affect the contact. The gold contacts inside the socket consist of
three spring tabs which bend slightly upwards towards the sensor. Make sure they are not
bent away, damaged or dirty.
Swap a different sensor into that location from somewhere that is known to be working.
This will eliminate a faulty sensor
Please contact Customer Service if you cannot resolve this problem and the location
seems to be failing for each fitting and all users.
