CHAPTER 1
About the Manual
Congratulations on the purchase of your new Cognionics Quick Series Dry EEG
Headset. This manual is organized as a detailed step-by-step guide on setting up
and using the device. Please read through the entire manual first to familiarize
yourself with the operation of your headset before proceeding with your first
recording.
1.1 The Quick-20 and the Quick-30
This documentation is written for both the Quick-20 and the Quick-30, as they
share many characteristics. Both have the same fundamental 10/20 channel
layout, though the Quick-30 has 10 additional channels in addition to the
standard 10/20 channels. The Quick-20 contains two grounds in the outer
sensors of the two dual-pods in the front, while the Quick-30 contains one
ground, which is located in the center of the triple pod in the front. The
Quick-30 also has two dual pods in the back of the headset. Regardless of
which headset you’ve received, this documentation serves as a guide to help
you set up and use your headset. In addition, our wiki contains resources to
help you get started with your Quick-20 or Quick-30 headset. It is located at
http://www.cognionics.com/wiki/.
Note: The Quick-20 and Quick-30 are for investigational use only. They
are not FDA-approved medical devices.

About the Quick Headsets
3.1 Parts of the Headset
The Cognionics Quick-20 and Quick-30 integrate the EEG amplifier and wireless
transmitter into an easy-to-use, self-contained headset. The main components
include:
1. Power Button - Push button to turn the headset on and o↵.Thepower
button is also used as a reset switch to bring the amplifier’s settings to
their default values. To reset the device, turn the headset o↵. Then press
and hold the power button until the main power LED flashes blue.
2. Battery Compartment - The Quick-20 and Quick-30 contain two battery
compartments. The Lithium-ion rechargeable batteries can be hot swapped
during use.
3. Power LED - Indicator of power and battery status. See picture for
description of LED color codes.
4. Trigger LED - Indicator of trigger link status. See picture for description
of LED color codes.
5. flexible Leg - The headset uses an array of flexible legs to conform to
di↵erent head sizes and shapes.

3. About the Quick Headsets
6. Sensor Pod - Each sensor pod is capable of swiveling to match the
contours of the head. The pod also houses an active amplifier to bu↵er
the EEG signal and a conductive outer layer, forming a faraday cage, to
shield the electrode from external electrical interference.
7. Sensor Connector - Sensors are attached via a miniature snap connector.
8. Accessory Connector - The Quick headsets have a port for attaching
an Auxiliary Input Module for external sensors. The port can also be used
with the wired data dongle.
Do not connect your headset to a standard USB port.
9. microSD Card Slot - The Quick-20 and Quick-30 accept microSD cards
for recording to flash memory.
10. Ear Band - flexible band supporting the ear pads.
11. Ear Pad - Cushioned pad to cup around the subject’s ear.
12. Ear Clip Connector - Jack for attaching the two ear clip wires for the
A1 and A2 positions.

3.2. Sensor Layout
3.2 Sensor Layout
The standard Quick-20 follows the international 10-20 layout with a total of 23
electrode positions (20-channels plus reference plus 2 grounds). The standard
Quick-30 incorporates all of these positions as well as 10 extra channels. The
common reference is located at A1 via the ear clip. On the Quick-20, Two
grounds for redundancy are located adjacent to the Fp1 and Fp2 positions. On
the Quick-30, the ground is between Fp1 and Fp2. Note: some headsets have
custom layouts. If so, refer to your order for specifics.
Always ensure that reference and ground are physically touching the skin.
The impedance check and all of the channels rely on the reference and ground
electrodes having contact with the subject’s skin.

CHAPTER 4
Preparing the Headset
4.1 Inserting the Battery
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.
Both the Quick-30 and Quick-20 feature dual hot-swappable batteries on each
earpad. The devices 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.

4. Preparing the Headset
a b
(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.
18

4.2. Installing the Sensors
4.2 Installing the Sensors
a b
Flex sensors should be used on areas with hair. On most subjects, this is all
positions except for Fp1, Fp2, F7 and F8. Positions where the subject has
no hair should be equipped with drypad sensors. (a) Grasp the sensor and
(b) push down on the center of the sensor into the receptacle.
When inserting sensors, always push at the center of the sensor. For flex
sensors, do not apply pressure or bend the sensor tips to avoid damage. When
removing sensors, always pry between the sensor and the connector. Do not pull
on the tips of the flex sensors to avoid damage.

4. Preparing the Headset
a b
(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.
ba
(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. You should feel a
’click’ when the connector is fully seated.
