Device Overview
Quick-20m Overview
EEG is the measurement — through the use of sensors and
ampliers — of scalp surface electrical potentials arising
from activity in the cortex.
The Quick-20m follows the international 10-20 system
standardizing electrode placements across the scalp. The
10-20 system derives its name from measurements of 10%
and 20% of the distance between landmarks on the head,
specically, the depression above the bridge of the nose
(nasion), the bump at the back of the head (inion), and the
depressions in front of each ear (preauricular points).
Sensors are labeled with a combination of letters and
numbers indicating their respective locations, with even
numbers on the right and odd numbers on the left side of
the head. Midline locations are marked with a “z” for “zero.”
For instance, Fz sits on the frontal midline, while F3 sits left
of and F4 sits right of Fz.
The Quick-20m is sized to t heads with a circumference
between 52 and 62 cm as measured about the thickest
part of the skull.
The Quick-20m meets the
mechanical, electrical, and
sensor needs required to
make an eective dry EEG
system.
Conventional wet systems
rely on electrolytic gels
to penetrate hair, contact
the skin, and provide a
conductive path. The gel
serves as a buer lling in
gaps between the sensor and
skin.
No conductive gel is used in a
dry system. The benets are
obvious: faster set-up, and no
after-use clean-up required.
Yet, dry systems are prone
to several challenges. First,
the sensor must be designed
to directly touch the scalp or
skin, even through thick hair.
Second, the sensor must
remain securely in place to
minimize artifacts and noise.
Finally, the electronics must
tolerate impedances up to
200 times higher than wet
systems — while rejecting
noise and interference. A
high-end dry solution — like
the Quick-20m — balances
sensors, mechanics and
electronics achieving virtually
the same signal quality as a
traditional wet cap for most
EEG applications.

9. Optimize Sensor Contact
After properly positioning the headset on the patient, obtain
direct contact on all sensors before recording.
The range of impedances with dry sensors may be higher
than what you are accustomed to when working with
conventional wet sensor ampliers. CGX devices utilize
a combination of advanced electronics, shielding, and
mechanics to obtain EEG signals even when contact is
poor, and can tolerate sensor impedance up to 5,000 kΩ.
10. Start Third-Party EEG Analysis Software
Start third-party software. Connect Quick-20m to
software according to third-party EEG Analysis software
manufacturer’s directions.
11. Adjust Pods, If Required, To Improve
Impedance Measurements
Start the impedance check function on third-party software.
Check for acceptable impedance measurements on each
channel.
A1 Reference and Ground earclip must be applied for
impedance check to operate.
To ensure good impedance measurements:
• Gently pull down on the handles until the Cz position
reports adequate contact.
It is important the headset is seated properly in the
correct position and all legs and pods are aligned with
the patient’s head before pulling down. Failure to do
so may result in poor contact at the Cz position.
• Lift the pod slightly to move hair aside.
• Lower the pod back in place, keeping the sensor aligned
to the patient’s head.
• Gently twist the sensor adjustment back and forth to help
move the sensor through the patient’s hair.
• Lightly press down on the pod, holding for 5 seconds,
then gently release the pod.

17
The most important aspect of EEG recording is that
output data is only as good as the recording input. While
algorithms exist to remove artifacts, poorly recorded data
cannot be xed in post processing.
Recording good EEG data requires preparation of the
participant for optimal sensor contact:
1. Participants should have their hair recently washed
and fully dried before recording. Wet hair, hair gel,
conditioners, and hair spray may cause interference and
degrade signal quality.
2. Clean the head directly below the intended sensor
location with a 70% isopropyl-based alcohol wipe.
3. In the event of diculty establishing good contact, apply
a small amount of water between the sensor and scalp
to create an electrical bridge.
4. It is important for patients to reduce tension in the head,
neck, and shoulders during readings.
Obtaining Clean EEG Data
Quick-20m sensor locations
lie within 1.0 centimeter on
the vast majority of hand-
measured 10-20 placements
on heads sized from 52-62
centimeters.
Quick-20m EEG data should
only be read and interpreted
by a qualied physician.
Preventative Care To Maintain Safety And Effectiveness
