EPOC X provides coverage of the frontal and prefrontal lobes; it also provides coverage of the temporal, parietal and occipital lobes. The image above shows the sensor locations for EPOC X using the international 10-20 system.

EPOC X has two electrode arms — each containing 9 locations (7 sensors + 2 references). Two sensor locations (M1 / M2) already have comfort pads fitted as they are the alternative reference positions (P3 / P4).

Each headset is packed with a small bottle of multipurpose contact lens solution. When you have finished this bottle, we recommend that you purchase further contact lens solution from a drugstore or pharmacy. Do not use contact lens cleaning or sterilizing solutions. Multipurpose contact lens solution contains non-allergenic anti-microbial agents that help to keep the sensors clean and prevent the transfer of microbes between users.

You can also make your own saline solution using 1tsp salt to 1L of water. This will achieve between 0.7% – 4% w-w sodium chloride; approximately the saltiness of sweat. We recommend adding a small quantity (< 4% by volume) of household disinfectant — such as 70% isopropyl alcohol. To reduce the rate of evaporation, also add a couple of drops of glycerin. Both of these products are available from a drugstore or pharmacy.

Your EPOC X is charged and tested before shipping — so you can start using it straight away.

Charging the battery

To optimize the use of your headset, we recommend that you fully charge it before making recordings.

If the ON/OFF LED does not glow white when you turn your headset ON, it requires charging.

To charge the battery, plug the USB charging cable into the USB-C port located on the right-side of the headset. Then, connect the other end of the USB charging cable to a power outlet or PC/Mac.

The length of time it takes to fully recharge your headset depends on the remaining capacity of the lithium polymer battery. Charging can take up to two hours.

If the headset is unused for a long period of time, the battery will become heavily depleted of charge. If this happens, you may need to charge your headset for 24-hours.

If you have any issues charging your headset, please contact the EMOTIV Support team.

Hydrating The Sensor Felts To hydrate the sensor felts, place them in a glass then add the saline solution and soak. When the sensor felts are fully soaked, remove them from the glass and squeeze out the excess fluid. They are now ready to be inserted into the sensors.

Rehydrating the sensor felts while the headset is in use If you need to rehydrate the sensor felts while the headset is being worn, you can add saline solution to each individual sensor felt using the opening at the top of each sensor. This feature enables you to continue using the headset and not disturb your session.

• EPOC X is a consumer product; it is not intended to be used as a medical device or in hazardous environments.

• EPOC X is designed for use at room temperature; rapid changes in temperature will affect the performance of the amplifiers and increase the noise floor.

• EPOC X uses saline based sensors. Every effort has been made to stop water entering the headset and protect the electronics inside. However, the headset is not waterproof. Do not submerge your headset in water.

• WARNING: EPOC X is powered by a lithium polymer battery that is rated for operation in <50°c environments. It is not user replaceable. If you suspect that there is a fault with the battery, please contact EMOTIV Support.

To connect your EPOC X headset to your PC or Mac you can either use the provided USB receiver dongle or Bluetooth Low Energy. The USB receiver dongle provides a dedicated and stable connection to your chosen EMOTIV application. Bluetooth Low Energy connections can be shared with other devices.

The USB receiver dongle uses a proprietary 2.4 GHz protocol to stream data from your headset.

We recommend that you use the USB receiver dongle in environments with high levels of Bluetooth interference.

1. Insert the USB receiver dongle into the USB port of your PC or Mac. When the USB receiver dongle is inserted into the port, one LED will light up.

2. Press the power button on the headset. The headset will then beep and the LED next to the power button will turnwhite.

3. After the headset is turned on, a second LED on the USB receiver dongle will light up and start to flash. Your headset and USB receiver dongle are now connected.

For further information on setting up the connection with your chosen EMOTIV application, please refer to the relevant user manual.

EPOC X comes shipped with rubber comfort pads set at the mastoid sensor locations as default. Which means the default referencing in EPOCX devices is P3/P4 referencing. Please see image below as reference.

EPOC X can be operated with the rubber comfort pads in the M1/M2 sensor positions, as well as the P3/P4 positions. To switch to mastoid referencing from the default, take the rubber pads out from the M1/M2 sensors and insert them into P3/P4 sensor positions. Ensure wet felt pads on all other sensors including M1/M2 to ensure mastoid referencing. Please see image below as reference.

You can change the configuration of the reference sensors at any time between recordings, whilst they are not in use. The rubber pads can be removed by twisting them out in the same way that the felt sensors can be twisted out. Simply remove them in this fashion from their existing positions, and insert them into the desired positions.

Before fitting the headset onto your participant, you must choose if you want to have the headband at the top or the rear of their head.

To adjust the headband, hold the arm and push the headband up or down to rotate. The headband will lock into place. To readjust the headband, repeat this process.

When you rotate the headband, update the settings in your chosen EMOTIV application so that the motion data can be interpreted correctly.

For further information on adjusting the sensors, refer to your EMOTIV application guide.

Incorrect positioning of the sensors and/or dry sensors are two of the most common reasons for poor contact quality.

If you do not see green sensors on the headmap in your chosen EMOTIV application, the contact quality is not good enough to take recordings.

To achieve the best contact quality for your recordings, we recommend the following:

• If a participant has thick hair, work the sensors through their hair to create a better contact with the scalp.

• Ensure that the sensor felts are wet enough. A guide to hydrating the sensor felts can be found in this .

• If a sensor is persistently not making good contact, you can test its functionality by tapping on the sensor and then observing what appears on the EEG data stream. You can also try measuring an ECG (electrocardiogram) signal by touching both references with one hand and the sensor with the other hand (image 1). You should be able to see the QRS and T-wave in your EMOTIV chosen application (image 2).

• Check your reference locations. These can be changed if you are having issues with the signal quality — such as fitting the headset to a participant with thick hair. Try the alternative marked locations CMS2 (M2) / DRL2 (M1) — on the headset — and place them at the mastoid.

When your EPOC X is not in use, remove all the sensor felts from the headset and allow them to dry out before storing them. Do not leave the sensor felts in the sensors. Leaving wet sensor felts in the sensors will corrode the electrodes. Store used sensor felts separately to unused ones.

To keep the headset in optimum condition please rinse the sensors with sterile water after use to remove excess salt. EPOC X’s electrodes are electroplated and keeping them clean will minimise corrosion.

Store your EPOC X in the travel case provided.
