What is inside the box

  1. 1 Cap
  2. 1 Left Cable Set (Blue)
  3. 1 Right Cable Set (Red)
  4. Both Cable Sets Attached to White Connector
  5. 1 USB Infrared Dongle
  6. FlexGEL ONLY : Easycap Gel Kit + Ear Clips

STEP 1

Configuring your sensor placement

There are 32 Sensors that you can configure depending on your purposes. We recommend using the universal 10-20 System for EEG placement. In total, there are 72 placement positions in the cap. Decide on your configuration before attaching the Sensors to the cap.

Flex Saline (felt) Sensors

The A-Q labels are written next to the sensor itself where the cable is attached.

Flex Gel Sensors

The A-Q labels are written along the cable with a white wrap-around label.

STEP 1

When your sensors are positioned, use the configuration option in EmotivPRO software package to allocate the correct labels to each sensor. Your headset must be connected to access the configuration page. Configurations may be saved for future use. The configuration will be retained until a change is made.

Note: The cables labeled A-H are 32 cm long. J-Q are 16 cm and they are designed to be placed closer to the control box (towards the back of the head). Keep this in mind while fitting the sensors to the cap.

Cables A-Q as well as the DRL reference (right) and CMS reference (left) are labelled on the cables themselves and they will match the designated positions on the control box when you insert the connectors after fitting the sensors to the cap.

STEP 2A (FLEX GEL)

Inserting the Sensors into the cap

Hold the underside of the cap, stretch the material in all directions around the hole you intend to fit, then wedge the sensor into the hole. Push upwards first and then let the material move to fix the bottom half. Adjust the material until the sensor is fully fixed. Repeat this step for all the Sensors in your desired configuration.

STEP 2B (FLEX SALINE)

Inserting the Sensors into the cap

Since the Saline Sensors are a little larger than the Gel Sensors, it is easier to stretch the material of the cap around the Sensors than forcing the Sensor into the cap.

With the saline felt pad facing inwards, place it over the Sensor hole into which you wish to fit it. Flipping the Cap inside out, stretch the hole over the Sensor, let the material pop into place into the plastic groove. The majority of the Sensor should be on the outer side, while the felt should protrude towards the inside, where it will be resting against the scalp when the cap is in place. Repeat this step for all Sensors.

STEP 2C (FLEX SALINE)

Adding the rubber skirts (Optional)

If you are taking long recordings, we have supplied some rubber skirts to reduce evaporation of saline solution over time. These skirts should be fitted on the underside of the cap – easiest option is to do this once the main Sensor is already fitted.

STEP 3

Placing the control box in position

Place the control box in either the rear head position or the top position. The top position is recommended for those who research on people where headrests are required in a chair (in wheelchairs, for example), or in studies where people are lying down (sleep studies).

With the EMOTIV logo facing outwards, stretch the fabric into the groove around the circular part of the control box securing the box in place.

The EMOTIV logo should be right way up, with the switch and cable ports along the lower edge. In the top position, the switch and cable ports should be along the rear edge.

STEP 4

Plug the cables into the control box

Plug the white connector (attached to all your red cables) into the right hand side of the control box. The connector only fits in one way, so if it fits in, then you have successfully connected your control box! Repeat the process for the left side (blue cables).

Double check all your cables are in the right place – you are almost ready for recording!

STEP 5

Tidying Up your wires

If you need to tidy up your wires, use the black cable ties and the needle provided to lock your cables down and prevent any unwanted movement. This is like “sewing” the cables into the material.

Threading

Thread the “T” Section of your cable tie through the threader in the needle as shown above.

Sticking the Needle

Through the bottom section of where you wish to tie the cables, stick the needle through 2 points of material

Pushing the Needle

Push the needle ALL the way thorough.

STEP 5 CONTINUED

Tidying Up your wires

On the other side of the cables if you want to tie down:

Rethreading

Re-thread other “T” in the black cable into the tip of the needle

Repeating the Process

Repeat the process as before, push the needle all the way through 2 layers of material:

Pulling the Needle

Slowly, pull the needle back and out, the black “T” should begin to slide out of the needle, keep pulling the needle out until the cable is attached on both sides of the wires.

Adjusting the Needle

Adjust the needle to fit.

6A (GEL)

When your recording is ready, get your gel sensors ready

On the participant, clean the skin of the forehead, the ears and behind the ears with a degreasing agent such as alcohol (dip the cotton end of a wooden swab in alcohol and degrease the skin by rotating on the spot).

    1. With a cotton wool bud, clean the skin of the forehead, the ears and behind the ears with the abrasive Gel in your kit. Work in firm, circular motions to abrade the area. Wipe the areas down with a clean cotton wool bud to remove any residue.
    2. Place the Cap on the participant’s head, aligning Cz according to the 10-20 System (half way between the Nasion and Inion)
    3. With the cotton swab, dip in abrasive gel, abrade the skin by rotating the swab in the hole of the ring-shaped electrodes.
    4. Using the syringe, apply a generous amount of electrolyte gel through the hole, onto the scalp that you just prepared.
    5. Repeat for all sensors, check your signal quality in EmotivPRO when you are finished.

Note: As most electrolyte gels permeate the skin, fill all electrodes before checking the signal quality. Most problems result from insufficient contact between skin and gel or gel and Sensor.

Important: Signal quality will not be visible until both CMS and DRL reference Sensors are fitted and at least one other Sensor. You may need to improve the both the references and the first Sensor until at least one GREEN indicator is shown. Subsequently, you should only need to improve the Sensor that you are working.

6B (SALINE)

When ready to record, hydrate your Sensors

Saline Sensors should be hydrated when you are ready for recording. It is recommended your first hydration should be done directly from the underside of the cap, directly onto the felt pads.

Alternatively, you can remove all of the felt pads, soak them in bulk saline solution, squeeze them gently to remove excess fluid and then fit them into each sensor location.

If the Sensors dry out or you have a particularly long recording, you can re-hydrate the sensors through the hole in the top of the sensor.

Note: The Flex Saline system includes skirts which may be fitted inside of each Sensor. These skirts reduce evaporative loss and reduce the tendency of the fluid to spread out if excess fluid is applied.
