The EPOC Flex is a 32-channel, flexible EEG system. It was built on the award winning EPOC+ technology and is designed for researchers who would like to have a more flexible sensor placement and / or greater density of sensors. The reference sensors can be placed in any location on the ear with included earclips. EmotivPRO v1.4+ is required for operation. If you have any queries beyond the scope of this document, please contact us through our online support. Safety Precautions ● EPOC Flex is a consumer product, it is not intended to use be used for in-patient health care or in hazardous environments. ● EPOC Flex is designed to be used at room temperature; rapid changes in temperature will affect the performance of the amplifiers and increase the noise floor. ● EPOC Flex can be used with gel or saline based sensors. ● 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 Flex while wearing the device. In the unlikely event your PC has a faulty power supply you and your headset could unintentionally become the ground path and so If EPOC Flex detects a USB connection when turned on it will stop communicating.

EMOTIV EPOC Flex Manual 5 of 15 EMOTIV EPOC Flex Manual 6 of 15 Controller Assembly› The EPOC Flex controller pictured above has 16 channels connected on the left + CMS input and 16 channels on the right + DRL output. These channels are connected in two rows A-H and J-Q, In software L or R is added in front to make it LA, LB, etc and RA, RB, etc. These labels allow users to easily trace signal problems from the name shown on software to the sensor. The connectors shown are JST PHD-18VS which are easily sourced from digikey if replacements are required. EMOTIV EPOC Flex Manual 7 of 15 Charging and LED Indicators The EPOC Flex has a single RGB LED to indicate power on and charging as shown in the table below. Action LED Colour Power OFF / Battery Flat OFF Powered On BLUE USB connected / Charging ORANGE Charge complete GREEN Firmware failure Fade On - Fade Off Blue USB connected / powered On WHITE It is recommended that your headset is fully charged prior to taking recordings. The charge time depends on the remaining capacity in the Lithium Polymer cell and can take up to four hours. If the EPOC Flex LED does not turn blue on power on it requires charging. Please use the provided USB Micro-B cable to recharge using any usb port. Note 1: The headset will charge faster if connected to a dedicated USB port. Note 2: If the headset it heavily depleted or hasn’t been used for a few months, leave it connected for 24hrs. EMOTIV EPOC Flex Manual 8 of 15 Electrode Assemblies Emotiv has developed the EPOC Flex to use EasyCap Multi-rode gel sensors that are pre-configured and easy to setup. The electrodes are attached to 150mm of tinsel wire and terminated with JST gold plated crimps. This length is designed to be long enough to reach any position on the cap. Electrodes are colour coded, blue for left, red for right and black for references. In addition each sensor will be individually labelled with the channel name connected. The aim of this colour coding is simple, when troubleshooting you can quickly identify the colour and channel name in the software and quickly find the electrode on the cap. There will be excess wire once the cap is fitted, we recommend that you place a cap over the top to stop these wires catching. If your research involves minimising motion artifacts keeping the excess wire secured will be required, either by tidying down the wire or feeding through adjacent empty holes. If a cap with electrode leads cut to length is required please contact us. We know that researchers can have different needs for references, so we have included earclips and adhesive pads that fit the electrodes. Example Electrode placement Below is an example image showing the electrode placement as per the initial setup in EmotivPRO. This placement gives good coverage of the entire head, with the pod fitted in the back pocket. EMOTIV EPOC Flex Manual 9 of 15 EMOTIV EPOC Flex Manual 10 of 15 EPOC Flex Cap The standard EPOC Flex cap follows the official 10-20 system and has 72 openings as shown above. The controller has two pockets it can be placed in on the cap, one is fitted about Cz and the other Iz. The caps can be ordered in our standard sizes are 54, 56 and 58 cm in a black high comfort material in a caucasian cut. Other sizes, hole positions, materials and cuts are available please contact online support for further information. EMOTIV EPOC Flex Manual 11 of 15 Specifying Cap Size Specifying the right cap size is critical for keeping for ensuring the sensors are in the right place when taking measurements. Our supplier recommends measuring the head diameter in the horizontal circumference as shown in the image below. Once you have the measurement for your test subjects you specify the closest size to the ones available for example 54.5cm → 54cm, 59cm → 58cm, etc. If you need larger or smaller sizes please contact support.
