Safety Precautions
EPOC+ is a consumer product; it is not intended to use for in-patient healthcare or in
hazardous environments.
EPOC+ is designed to use at room temperature; rapid changes in temperature will
affect the performance of the amplifiers and increase the noise floor.
EPOC+ uses saline based sensors and every effort has been made to protect the
electronics from water ingress, however it is not waterproof. Please do not submerge
your headset.
WARNING : EPOC+ is powered by a Lithium-Polymer battery that is rated for operation in
<45C environments. It is not user replaceable, please contact support if you suspect a fault
or have any questions.
WARNING : Do not open the enclosure. Doing so will void the warranty and can damage the
headset.
WARNING : Do not charge EPOC+ while wearing the device. In the unlikely event if your PC
has a faulty power supply, you and your headset could unintentionally become the ground
path. If EPOC+ detects a USB connection when turned on, it will stop communicating. If you
would like to use it tethered, please use an EMOTIV Extender. Extender provides USB
isolation and charging protection while tethered.

Using your headset

EPOC+ Headset Details
The EPOC+ has two electrode arms each containing 9 locations (7 sensors + 2 references).
Two sensor locations (M1 / M2) already have rubber sensors fitted because they are the
alternative positions for the default references (P3 / P4).
The EPOC+ is designed to provide good coverage of the frontal and prefrontal lobes and
also provides coverage of the temporal, parietal and occipital lobes. The images shown
above are the sensor locations for the EPOC+ using the international 10-20 system.

LED Indicators
The USB port, power switch and LED indicators are part of the control board which sits in
the middle of the EPOC+ headband. The power LED is located on the top surface and the
charging LED is on the USB face.
The following table outlines their behavior:

Charging
It is recommended that your headset is fully charged prior to capture recordings. The
charge time depends on the remaining capacity in the Lithium Polymer cell and can take up
to four hours. If the power LED does not glow white when you turn it On, your EPOC+
requires charging. Please plug-in the provided USB Mini-B cable into the headset as shown
above to USB port.
Note 1: The headset will charge faster if it is connected to a dedicated USB port.
Note 2: If the headset is heavily depleted or hasn’t been used for a few months, leave it
connected for 24 hours.

Universal USB Receiver (Dongle)
The universal USB receiver (dongle) uses a proprietary 2.4 GHz protocol to stream data
from the headset. We recommend using this to connect to your headset on a PC or Laptop;
once connected it remembers the serial number of the headset pairs to allow easy
reconnection. The dongle pairing also allows multiple headsets to co-exist and provides a
reliable high speed connection over Bluetooth Low Energy (BLE).
The headset supports BLE which allows connection to mobile devices (Android/iOS) and
some computers. EmotivPRO does support the native BLE radio on MacOS devices (2015
or later). On PC's however the implementation of Bluetooth varies by manufacturer and it is
not guaranteed to work and so we recommend using the dongle.
There are two green LED's on the top surface of the dongle and plastic lies at the bottom.
The following table explains about LED's.
