Description
The Quick-32r is a wireless, battery-
operated EEG headset utilizing dry
sensor technology. Channel positions
are arranged in an enhanced 10-20
montage with 10 additional fixed EEG
channels on the head, plus 2 variable-
placement ExG channels.
The headset provides an integrated
approach to the wireless acquisition
of recorded of EEG signals. Wireless
technology allows the subject to move
about while real-time data is collected
and displayed.
The headset obtains high-quality
EEG with minimal scalp preparation.
Patented mechanisms and replaceable
dry sensors align to various head
shapes and sizes, maintaining sensor
positions in a standard montage.
EEG channels are sampled at a time
resolution of 500Hz and converted to
digital data at 24 bits of resolution.
The Quick-32r provides research-
grade signal quality and is ideally
suited for general-purpose EEG and
ERP research in laboratory and field
environments.

ThisDeviceIsIntendedForResearchOnly.
ItIsNotIntendedForTheFollowingUses:
• monitoring of patients in a clinical
environment
• use in medical diagnosis
• on subjects undergoing surgery
• use in sterile environments
• use with sleeping subjects
DoNotUseThisProductInThese
Situations:
• near high-frequency surgical equipment
• if exposed to ionizing radiation
• in oxygen-rich environments (concentration
> 25% at 1 atm)
• in wet environments
• in the presence of ammable anesthetics
or gases
PrecautionsForThePractitioner
• Do not drop, sit on, step on, fold, push,
pull or stretch the product.
• Check if your subject has a sensitive
dermatological condition causing sensor
intolerance.
• To avoid cross-subject contamination, do
not use with subjects having open wounds
or scalp infections.
• The Quick-32r headset is not a diagnostic
tool. Any medical diagnosis related to
the EEG should be derived by a certied
physician.
SubjectConsiderations
• This device is intended for human use only.
• Subject should have a healthy scalp.
• This device ts teens and adults with a
head circumference from 52 to 62 cm.
• Do not use with infants or neonates.
• Test subjects may or may not have hair.
• All sensors must be able to contact the
subject’s scalp.
• The entire headset may come into contact
with the subject’s skin.
FollowTheseAdvisoriesToKeepYour
Quick-32rInGoodWorkingOrder
• Do not immerse the headset in liquid.
• Do not expose the headset to direct
sunlight or heat source, moisture, vibration,
mechanical shock, excessive dust, or
humidity.
• Do not open, modify or disassemble the
headset — this will void the warranty.
• Do not use if the headset is damaged.
• Do not use when wet — if moisture
penetrates the headset, remove the
batteries and let it thoroughly dry prior to
use.
• Do not use caustic or abrasive cleaners on
the headset or sensors.
• Avoid sharply bending the legs.
DisposableSensorsMayBeA
Biohazard
• Store clean sensors in the provided jars.
• Clean sensors after each session following
instructions on Page 13.
• Replace sensors at or before their stated
lifecycle limits (Specications, Page 26), or
if they appear worn.
AlwaysUseSuppliedAccessories
Using accessories other than those supplied
with your Quick-32r system may result in
damage or diminished ecacy of the system.
The Quick-32r uses two AA Alkaline or
NiMH batteries. Follow care and handling
instructions provided by the battery
manufacturer.
AvoidCross-SubjectContamination
Clean the device and clean or replace
sensors after use following the cleaning
instructions on Page 13 to avoid cross-
subject contamination.

DeviceOverview
Quick-32rOverview
EEG is the measurement — through the use of sensors and
ampliers — of scalp surface electrical potentials arising
from activity in the cortex.
The Quick-32r follows an enhanced international 10-20
system standardizing 30 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, specically, 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-32r is sized to t most adult head sizes. See
sizing chart on Page 27.
The Quick-32r meets the
mechanical, electrical, and
sensor needs required to
make an eective 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 buer lling in
gaps between the sensor and
skin.
No conductive gel is used in a
dry system. The benets are
obvious: faster set-up, and no
after-use clean-up required.
Yet, dry systems are subject
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-32r — balances
sensors, mechanics and
electronics achieving virtually
the same signal quality as a
traditional wet cap for most
EEG applications.
