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
adj acent t o t he Fp1 and Fp2 posit ions. Not e: some headset s have cust om
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

Care and Handl i ng
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
not e of t he following it ems:
•Avoid excessively bending the legs or earband
-TheQuick-20relies
on t he flexibilit y of t he leg mat erial t o deflect and conform across t he
many variat ions in head shapes. Do not grab and deliberat ely bend t he
legs or ear bands beyond the range necessary to apply the system on a
subj ect .
•Never connect the Quick-20 to a standard USB port
-Themi-
croUSB port on t he Quick-20 is designed t o work only wit h Cognionics
accessories, which provide elect rical isolat ion t o prot ect t he headset and
subj ect f r om el ect r i cal shock. Di r ect l y connect i ng t he Qui ck -20 t o a
PC, wit hout t he special isolat ion dongle, will not work. Connect ing t he
Quick-20 t o a USB port will not recharge t he bat t eries. Misuse of t he
USB port may result in damage t o t he headset .
•Do not immerse the headset in a liquid
-Whencleaningthesystem
wit h isopropyl or sanit izer, use just enough liquid t o moist en t he brush.
Avoid dispensing liquid into the sensor pods or any other opening in the
headset t o prevent damage t o t he headset ’s elect ronics.
•Do not compress the legs of the headset
-Usethesuppliedcarrying

5. Pr epar ing t he 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.

5.2. Installing the Sensors
5.2 Installing the Sensors
a b
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
wit h light or no hair, insert drypad sensors.
When inserting sensors, always push at the center of the sensor. For flex
sensor s, do not appl y pr essur e or b end t he sensor t i ps t o avoi d 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.
