Page 14: Sensor Layout
3.2. Sensor Layout 3.2 Sensor Layout The Quick-20 follows the international 10-20 layout with a total of 23 electrode positions (20-channels plus reference plus 2 grounds). The common reference is located at A1 via the ear clip. Two grounds, for redundancy, are located adjacent to the Fp1 and Fp2 positions. -

Page 16: Care And Handling
CHAPTER Care and Handling The Quick-20 is designed to be a robust, durable headset suitable for use in real-world environments. To keep your Quick-20 functioning optimally, take note of the following items: • Avoid excessively bending the legs or earband - The Quick-20 relies on the flexibility of the leg material to deflect and conform across the... - Page 17 4. Car e and Handl ing that apply pressure to the legs since long-term compression may cause the headset to deform. If the legs of the headset become compressed, the system may become tight and uncomfortable for the subject. • Do not pull on the ear clip wire - When removing the ear clip from the headset, grasp the base of the connector, rather than the wire.

Page 18: Preparing The Headset
Make sure the batteries are fully charged. Place the provided lithium-ion batteries into the charger and wait until the charger indicates that the battery is full. The Quick-20 features dual hot-swappable batteries on each earpad. The device will function with a battery in either, or both, compartments. If both batteries are inserted, the right hand side battery will be used to recharge the left side battery. - Page 19 5. Pr epar ing t he Headset (a) Open the battery cover. (b) Insert one lithium-ion battery. Make sure that the battery is inserted in the correct orientation. The metal contacts on the battery should be oriented towards the top of the headset.

Page 20: Installing The Sensors
5.2. Installing the Sensors 5.2 Installing the Sensors Insert flex sensors for areas that are covered by hair. On most subjects, this is all positions except for Fp1, Fp2, F7 and F8. (a) Grasp the sensor and (b) push down on the center of the sensor into the receptacle. For areas with light or no hair, insert drypad sensors. - Page 21 5. Pr epar ing t he Headset (a) Grab the two supplied ear clip wires. Pinch the ear clip to expose the snap connector and (b) insert a drypad sensor, if one is not already installed. (a) Grab the connector end of the ear clip wire. (b) Firmly insert the connector into the jacks at the base of each ear band.

Page 22: Starting The Acquisition Software
If you are using Neuroguide, please refer to the Neuroguide documentation (http:/ / www.appliedneuroscience.com/ Tutorials.htm) to con- nect to the Quick-20, perform an impedance check and start recording EEG data. (a) Retrieve the Bluetooth Dongle and (b) insert it into your computer’s USB port. - Page 23 Quick-20 under ’Discovered Devices’. If you do not, please remove and re-insert the dongle, then restart the software. Select your Quick-20 and click on the ’Connect’ button. You should see a small pop-up window asking if you wish to auto-configure. Click ’Yes’. If you do not see the pop-up, check beneath the main window of the software.

Page 24: Applying The Headset And Optimizing Sensor Contact
Sensor Contact 6.1 Placing the Headset The Quick-20 is designed to be easily self-applied. However, we recommend that you first practice on another subject to familiarize yourself with the procedure. If you are attempting to self-apply the system, please have a mirror handy to help with the process. - Page 25 6. A ppl y ing t he Headset and Opt imizing Sensor Cont act (a) Grasp each ear band and pull them gently apart to open the Quick-20 and slide the system on to the subject’s head. Adjust the position of the headset so that the ear cups fit around the subject’s ears.
- Page 26 (b) Example of pod that is tilted. Grasp and rotate the pod so that the sensor is normal to the subject’s head. (a) Push the Quick-20 fully onto the subject’s head such that the crown (Cz) is touching the subject’s head. (b) Some of the sensor pods may be rotated in the incorrect position during the application process.
- Page 27 6. A ppl y ing t he Headset and Opt imizing Sensor Cont act (a) Lift the ear cup to access the ear lobe and pinch open the ear clip. (b) Place the ear clip on the earlobe of the subject. If the subject’s earlobe is too small for the drypad, you can alternatively place the drypad of ear clip on the back of the ear.
- Page 28 Ensure that the Quick-20 is not tilted too far towards the back of the head. Check again to see that all of the legs and pods are not tilted or misaligned before proceeding to the next steps.

Page 29: Optimizing Sensor Contact
After properly positioning the headset on the subject, the next step is to obtain su# cient contact on all sensors before proceeding with the EEG recording. For this step, you will need to bring up the impedance check in the Cognionics Data Acquisition software under the Channels tab. The impedance check presents a color coded map of the sensors in the headset. - Page 30 6.2. Optimizing Sensor Contact (a) First gently push down on the headset until (b) the Cz position (circled) reports adequate contact. If necessary, adjust the length of the ear bands to keep the headset and Cz in contact with the subject’s head. It is very important that the headset is seated properly in the correct position and that all of the legs and pods are correctly aligned with the subject’s head before pushing down.
- Page 31 6. A ppl y ing t he Headset and Opt imizing Sensor Cont act For each location that does not have su# cient contact, (a) grasp and lift the pod slightly. If the subject has dense hair, move aside the hair directly underneath the sensor pod.
- Page 32 6.2. Optimizing Sensor Contact If any sensor locations are particularly di# cult, you can apply a small amount of hand sanitizing liquid to help improve contact quality. (a) Dispense enough liquid to form a thin layer on your finger. (b) Transfer the liquid only to the tips on the sensor.

Page 36: Removal, Cleaning And Storage
The Quick-20 can be rapidly removed from the subject. Disconnect the ear clips from the subject’s earlobes. Grasp sides the of the Quick-20 with two hands and lift up. On subjects with thick hair, be gentle as the hair may become entangled with the sensors. -
