Preparing the equipment
Follow the steps described below to select a cap, correctly insert the
sensor sockets, and achieve the desired disposition of sensors.
2
To place a socket in the cap, identify
the corresponding location hole
(small labeled holes) and slightly
enlarge it with your nger. Insert the
socket from the inside of the cap
towards the outside, introducing it
through the hole until the fabric is
correctly placed in the slit, as shown
in the picture.
1
Measure the perimeter of the user’s
head and select the adequate cap
size. If none of the sizes t, please
contact Bitbrain to acquire the
correct size cap.

To remove a socket, place your thumb
on top of it and push towards the
inside with both hands until it slides
out of the fabric.*
To place a socket in a different
position, follow the instructions for
step 2.
*Please note that the cap material will
suffer a slight deformation when the
sockets are introduced, and therefore
frequent changing of positions could
stretch the cap.
4
Before placing the cap on the head,
insert the sensors. Press rmly on
the silicone to insert each sensor into
a socket. When placing the sensors
on the cap, ensure that the cables
are organized towards the back for
easy placement on the head.
NOTE:
Please take note of the positions
of the sensors (marked on the cap)
and the number of each sensor. Data
analysis requires this association.
Preparing the equipment

5
Organize the cables as shown in the
picture (towards the back of the
head).
6
Utilize the fastening band to keep
cables in the correct position and
prevent them from shifting during
operation of the device.

Prepare the necessary sponges for
the 18 electrodes (16 channels +
GND + REF) *.
Submerge the sponge in regular tap
water until it is completely wet.
8
To use a sponge electrode, roll it into
a cylinder, as shown in the picture.
Preparing the equipment
*If you need more sponges, contact the
Bitbrain team.

9
From the inside, introduce the damp
sponges in the inner holder on each
sensor on the cap.
Repeat steps 7 to 9 with the
remaining sensors.
Preparing the equipment
IMPORTANT:
Do not wet the EEG connector itself.
This could damage the device

Preparing to record data
1
Turn on the amplier by pressing
the power button ( ) until the light
blinks. The wireless connection
LED will flash until the connection
is established with the software.
The LED will then stay on. When the
battery device is low, the battery
indicator LED will turn on.
IMPORTANT:
Do not use the device while charging.
A low battery can adversely affect
the quality of the recorded signal
and it is recommended to charge the
system before starting a recording.

Preparing to record data
2
This equipment sends data using
Bluetooth wireless technology.
The data can be saved on:
•The computer with which the
device is paired. Note that
if the device loses Bluetooth
connection with the computer,
this can lead to a loss of data.
•MicroSD Card. In this mode, the
wireless signal will continue being
sent, so data can still be seen
and recorded in real time on the
computer while simultaneously
being saved on the memory card.
Pairing
Be sure the computer has a Bluetooth
adapter version 2.1 or higher. The
rst time you use the device, you will
need to pair it. This can be done from
“Settings > Devices” on Windows.
The name of the device in the list of
Bluetooth interfaces corresponds
to the serial number (S/N), which you
can nd printed on the label on the
amplier.
Data backup with MicroSD
1. Insert the MicroSD card provided
into the slot on the display.
2. Enable the “SD card record” option
on the software to save data to the
card.
The les saved are recorded in .sdf
format. To convert them to .csv format,
use the “Import record” function on the
software.
IMPORTANT:
We recommend using a Class 10 or
above Micro SD card with capacity of
8GB. Using another type of memory
card that does not meet these
specications could cause loss of
data.
