EMOTIV EPOC USER MANUAL | BRAIN COMPUTER INTERFACE TECHNOLOGY
Initial charging of headset
Make sure the small switch on the rear underside of the headset is set to the “Off”position before
starting.
Plug the mini USB cable attached to the supplied battery charger into the slot at the top of the
headset and to the USB port on your PC or the power cord into a 50 or 60 Hz 100-250 V electrical
outlet.
The Lithium battery can be recharged to 100% capacity in approximately 4 hours depending on the
initial state of charge. Charging for 30 minutes usually yields about a 10% increase in charge.
The EPOC Headset contains two status LEDs located at the rear and next to the power switch at
the back of the headband. When the power switch is set to the “on” position, the rear LED will
illuminate and appear blue if there is sufficient charge for correct operation, unless charging is in
progress. The charging LED will appear red during battery charging; when the battery is fully-
charged, the charging LED will display green.
NOTE: The Headset should not be charged when still on the head.
Software Installation
Insert the supplied EPOC CD setup disk into your computer's CD/DVD drive and follow the step-by-
step installation instructions.
After software installation, start-up the EPOC Control Panel program, loading the Headset Setup
screen.

EMOTIV EPOC USER MANUAL | BRAIN COMPUTER INTERFACE TECHNOLOGY
Hydrating the Sensors
Open the Saline Hydration Sensor Pack with the white felt inserts inside. The inserts will eventually
be mounted in the headset arms but must be properly wetted with saline solution first. Begin
wetting each of the felt inserts with the supplied saline solution. The felts should be wet to the
touch, but not soaking wet!
Note: This is standard multipurpose contact lens saline solution and is available from any local drug
store in case you run out of solution. However, the bottle supplied with the kit should be sufficient
initially. See the User Manual on the EPOC CD setup disk for recommendations.
Add a few drops of saline to saturate the large white hydrator pad attached to the top cover of the
hydrator, then close the cover and gently shake the hydrator pack. This will maintain the moisture
of the felt pads when they are not in use. Open the pack and check that each of the pads had been
wetted. If not fully wetted, then add a drop or two of saline to any pads not sufficiently wet using the
dropper bottle. Be careful not to over-wet the pads. If you have connection problems, add more
saline to each felt pad.

7
EMOTIV EPOC USER MANUAL | BRAIN COMPUTER INTERFACE TECHNOLOGY
Sensor Assembly
After the wetting process, remove the sensor units with their felt pads from the hydrator pack and
insert each one into the black plastic headset arms, turning each one clockwise one-quarter turn
until you feel a definite "click". The "click" indicates each sensor is correctly installed in a headset
arm. If you have difficulty with this step, apply a little more force until you feel the "click" but be
careful not to exert excessive force as damage might occur. Please see the Troubleshooting
section if the sensors do not click in place easily.
NOTE: When not in use, the sensor units should be removed from the headset arms and stored in
the hydrator pack for subsequent use.

EMOTIV EPOC USER MANUAL | BRAIN COMPUTER INTERFACE TECHNOLOGY
Pairing the Neuroheadset
Insert the supplied USB Transceiver Dongle into one of your computer's USB slots. Use a USB
extension cable and position the Transceiver in a prominent location away from your monitor and
PC to improve poor reception.
Then turn-on the headset using the switch at the bottom end of the headset, holding it close to the
Transceiver.
Headset Placement
You are now ready to put the EPOC headset on your head. Using both hands, slide the headset
down from the top of your head. Place the arms approximately as depicted, being careful to place
the sensors with the black rubber insert on the bone just behind each ear lobe. Correct placement
of the rubber sensor is critical for correct operation.

9
EMOTIV EPOC USER MANUAL | BRAIN COMPUTER INTERFACE TECHNOLOGY
Notice the 2 front sensors should be approximately at the hairline or about the width of 3 fingers
above your eyebrows.
After the headset is in position, press and hold the 2 reference sensors (located just above and
behind your ears) for about 5-10 seconds. Good contact of reference sensors is the key for a
good signal. Check that the lights corresponding to these 2 reference sensors turn from red to
green in the EPOC Control Panel Headset Setup screen.
Gently press and hold each remaining sensor against your scalp until all the lights corresponding to
those sensors turn to green in the EPOC Control Panel.

10
EMOTIV EPOC USER MANUAL | BRAIN COMPUTER INTERFACE TECHNOLOGY
If you are unable to get anything except 2 red sensors, add saline to the reference and other
sensors, or try the alternate reference locations –swap the reference sensors with the rubber
comfort pads located directly behind the ears, making sure the reference sensors contact directly
onto the bare skin on the bony bump.
Signal Quality Screen
Your objective is to achieve as many green lights as possible using the EPOC Control Panel and
adjusting the position of the various arms accordingly. (See full User Manual Document contained
on the CD for detailed instructions) Note that the EPOC will still function with some sensor locations
showing yellow or orange, and will even cope with a few red or black however the detections will be
less reliable in this state. Often the contact quality will gradually improve after a few minutes use, so
don’t be too discouraged if setup is not perfect at first.

2.1 Charging the EPOC Neuroheadset Battery
The Emotiv EPOC Neuroheadset contains a built-in rechargeable lithium battery which is designed
to run for approximately 12 hours when fully charged. To charge the EPOC battery, set the power
switch to the “off” position, and plug the EPOC Neuroheadset into the Emotiv battery charger using
the mini-USB cable provided with the EPOC Neuroheadset. Using the supplied battery charger, a
fully drained battery can be recharged to 100% capacity in approximately 6 hours; charging for 30
minutes usually yields about a 10% increase in charge.
The EPOC Neuroheadset contains a status LED located next to the power switch at the back of the
headband. When the power switch is set to the “on” position, the LED will illuminate and appear
blue if there is sufficient charge for correct operation. The LED will appear red during battery
charging; when the battery is fully-charged, the LED will display green.
NOTE 1: The Neuroheadset should not be charged when still on the head.
NOTE 2: Do not expose battery or neuroheadset to prolonged temperatures above 122F (50C).
Damage to the battery or neuroheadset may occur.

EMOTIV EPOC USER MANUAL | BRAIN COMPUTER INTERFACE TECHNOLOGY
2.2 Use of Saline Hydration Sensor Pack and Felt Inserts
Open the Saline Hydration Sensor Pack with the white felt inserts inside. The inserts will be
mounted in the neuroheadset arms but must be properly wetted with saline solution first. The
saline solution is harmless but allows the felt pads to make good contact with the skull when
properly positioned on the head. This is a very important step.
Pour a small amount of saline onto each of the sensors (6 or 7 drops if completely dry). Once you
have moistened the sensors, pour a small amount of saline onto the large white hydrator pad to
evenly moisten the entire pad. Close the hydrator and allow the sensors to absorb some of the
saline. You can shake or invert the hydrator unit so that the liquid is evenly distributed and
absorbed into the felt pads. Note: For user comfort the sensor pads should be damp but not
dripping wet. If the pads do not feel slightly wet, you may also place one or two more drops of the
solution directly on the pads from the top to speed the process of absorption.
Following the initial hydration step, each of the inserts must be removed from the pack and securely
mounted in the EPOC neuroheadset arms by turning the inserts one quarter turn to the right and
listen/feel for the click. If you do not hear or feel the click, try again until you do. A very firm force
may be needed the first couple of times but be careful not to exert excessive force or you may
damage the headset arms. Practice on the sockets in the hydrator a few times if you are unsure.
Ensure that each sensor is locked in place. Note that the sensor location behind the ears is fitted
with a soft rubber comfort pad. This should remain in place unless the normal Reference sensors
do not contact properly (see below for alternative Reference Sensor location)
The fully populated neuroheadset should look like this:

19
EMOTIV EPOC USER MANUAL | BRAIN COMPUTER INTERFACE TECHNOLOGY
After first use, the pads should be rewet the next time EPOC is used by using a dropper to wet the
sensors and hydrator pad again. The sensors should be removed from arms after use and stored
in the hydrator unit to keep the sensors moist for subsequent use.
Note on saline solution: When the initially provided saline solution has been exhausted,
additional saline should be purchased from a local drug store. We recommend the use of Multi-
purpose Contact Lens Solution if possible, but do not use Contact Lens Cleaning or Sterilizing
Solutions. Multi-purpose Solution contains non-allergenic anti-microbial agents which help to keep
your sensors fresh and prevent transfer of microbes between users. Normal saline between 0.7%
and 4% w-w sodium chloride may also be used, but we recommend adding a small quantity (no
more than 4% by volume) of a household disinfectant such as 70% iso-propyl alcohol.

20
EMOTIV EPOC USER MANUAL | BRAIN COMPUTER INTERFACE TECHNOLOGY
2.3USB Transceiver Installation
Plug the provided Emotiv USB transceiver into an unused USB port on your computer. After one or
two seconds you should see a single LED flashing slowly, or a single bright LED and another dim
LED if the transceiver has already paired with a nearby neuroheadset. The transceiver should be
recognized and installed automatically by your computer as a USB Human Interface Device. Please
wait for a moment until Windows indicates that the new hardware is installed and ready to use.
Hold the Emotiv EPOC close to the USB receiver, and turn it on using the switch at the rear of the
headband. You should see a new steady LED on the receiver, which indicates that the
neuroheadset has properly paired with the USB receiver, and a more dim LED which flashes
indicating successful data transfer.
2.4 EPOC Control Panel™
This section explains how to use EPOC Control Panel to explore the Emotiv detection suites.
Launch EPOC Control Panel by selecting Windows Start →Programs →Emotiv→ EPOC Control
Panel. When the Control Panel is launched for the first time, your firewall software (if installed on
your computer) may notify you that the Control Panel is trying to accept connections from the
network. For proper operation, you must allow EPOC Control Panel to use this port by selecting
“Unblock” (or a similar option, depending on your firewall software).
