WARNING

Do not use the EEG cap with removable passive Ag/AgCl electrodes and accessories (hereafter - product) for other

purposes than it is intended.

Use IEC 60601-1 standard to combine the product with other devices such as encephalograph. The operator bears

the responsibility for use of any devices together with a product. Use of a product with other devices should not lead
to failure and-or increase of a risk level of the operator and the patient. Using electrodes of the same type.

Do not operate the product within powerful radio interference producing sources such as arc welders, radio thermal

treatment equipment, x-ray machines or any other equipment that produces electrical sparks. Portable RF
communications equipment (including peripherals such as antenna cables and external antennas) should be used no
closer than 30 cm (12 inches) to any part of the product, including cables specified by the manufacturer. Otherwise,
degradation of the performance of this equipment could result. If such use is necessary, this equipment and the other
equipment should be observed to verify that they are operating normally.

Do not use in magnetic resonance imaging.
Always observe the safety requirements of this manual for operation and maintenance. If any problems don’t open the

product, do not unauthorized repairs, any doubts please contact your local supplier.

Take care of the product’s components. Avoid the cables’ breaks, kinks, tension, excessive stretching of the EEG cap

and other mechanical efforts. Take care of arranging cables/wires to avoid the risk of entanglement or strangulation.

Electrode sensors are fragile and require careful and caring treatment. Always put electrodes on a soft surface, such

as a napkin or a towel.

Reapply of a product present a potential risk of cross-infection especially when are used on abraded skin, unless they

are restricted to a single patient or disinfection between patients.

Use the special EEG electroconductive gel/paste for the EEG acquisition.

Common description

EEG-caps are made of elastic material that provides the most comfortable fit of the electrodes without additional

adjustment. Numerous holes are intended for ventilation and electrode alignment to head according to modified
combinatorial electrode nomenclature

1

.

Many sizes of cap cover the head sizes from 24 cm to 66 cm head circumference. EEG-cap fixed to the head using chin

belt or chest belt.
Reusable EEG electrodes have a channel for gel and the recording surface is silver/silver chloride (Ag/AgCl). Sintered

technology of sensors guaranties minimal polarization and long-term stability. Electrode contact with the skin is provided
through EEG gel.

EEG electrodes fixed to the EEG-cap using special fixing ring or the electrode hole on the cap. EEG electrodes are
connected to an electroencephalograph through single or united connectors.

INSTRUCTIONS FOR USE

STEP 1. Measure the circumference of the patient's head.

Head size measure around the fullest part of the head just above the ears using a flexible tape
measure. Taking the measurement at the forehead. Circumference of the head should be
measured at a point approximately one inch above the eyebrows or at whatever point gives the
largest possible measurement. After the measuring choose the proper cap size.

STEP 2. Put the cap on the patient.
Beginning from the front of head, where the subject may hold the edge of cap, pulling the cap

over of the head. Next, adjust the electrode position Cz halfway between Nasion and Inion. The
frontopolar and occipital electrode positions should now be placed correctly. Otherwise choose
another cap size. When measured correctly, the frontopolar electrodes (e.g. Fp1/Fp2) should lie
directly above the eye brows.

Make sure, that Cz is right-left-centered as well, and that lateral electrode positions are
symmetrical.

Affix the cap with the chin belt. Pay attention to the correct location of its. The wide part of a belt
should fit a chin and shouldn’t slump on the neck. The belt tension should provide reliable fixing
of cap.

Don’t pull in tight chin belt. The subject should feel comfortable even during long-term research.

Attach the cap on the head is possible with use the chest belt. This type of attachment is
effective in cases where during the test pressure of the chin strap hinders the patient's actions,
for example, if the patient should talk.

The chest belt is attached directly to the patient's chest. Chest belt is arranged in V-shape or X­shape, which contributes to a secure fit of the cap. Tension is regulated by the length of the
straps.

STEP 3. Insert the electrodes in the cap accordance with the research scheme.

Point EEG electrodes insert into fixing ring until it stops.
Cup EEG electrodes insert into electrode hole.
Pay attention that electrode cables are not confused and not bended.
To avoid confusion of wires, use coupler for wires. Insert a coupler tip through the hole at

the other end, strongly tighten and then fix a tip with velcro.

STEP 4. Connect the electrodes to the skin through EEG gel.
Fill the syringe with gel. Gel should not be too fluid nor too viscous. Set supplied the nozzle-

dispenser. The nozzle-dispenser should sit tightly on the syringe and should not hang or
subside. Use only supplied the nozzle-dispenser with blunt needle. Spiky needle can
damage patient skin.

Slide the hair directly under the EEG electrodes with use the nozzle-dispenser needle. It will
help to reduce the impedance and increase the quality of researches.

STEP 5. Fast connection.
In cases where it is necessary to promptly fast disconnect or connect the electrodes

mounted on the patient, for example, when registering somnogrammy, can be used passive
adapter. It can also be used when it is necessary to increase the distance from the patient
to the amplifier.

Minimizing impedances

Recommended to use electroencephalograph in mode of impedance measurement.
Insert a syringe needle of the nozzle-dispenser into a hole of electrode and squeeze out a
few gel. Then take out a needle from hole and remove remaining gel. If it has not given
results repeat procedure. If after that the impedance remains too high, check the electrode.

Maintenance

Electrodes and cap after use should be immediately cleared of gel while it has not dried up!

Recommended a thorough cleaning after each recording. For cleaning a product make sure it is not connected to an
electroencephalograph any more. Don’t wet the connectors!

The connectors must be max far from the any liquids!

For the cap with preinstalled electrodes: Don’t take electrodes from the cap with preinstalled electrodes for cleaning
after recording. Carefully clean the cap with electrodes together.

For the cap with removable electrodes and TouchProof connectors: Carefully take the electrodes from the cap:

- for a point EEG electrode with rotational motions remove it from the fixing ring;

- for a thin (cup) EEG electrodes pull site of cap portion near the hole of the electrode with another hand and remove the
electrode from the hole. Do not pull the electrode!

Under most circumstances cleaning of caps and electrodes is carried out in a detergent. Be attentive: dish-detergents
often leave a film. A children’s shampoo will be a good choice. Improper maintenance can lead to product damage. Do

not use abrasive materials, strong disinfectant solutions, for example, on acetone basis to product clearing.

For disinfection use 70% ethanol solution. Never soak a product in the solution but wipe it with soft gauze moistened with
ethanol. Before disinfection carefully wash out a product from the gel rests. Also, gas sterilization with ethylene oxide is
acceptable.

Warning

- do not soak electrodes in saline solution or chloride because salt is generally aggressive to the electrodes’ surface and
corrosion of connections will result;

- do not use autoclave or other hot sterilization methods because the wire insulation can be damaged.

Afterwards rinse the cap with warm water and the electrodes with distilled water. Finally dry them thoroughly with a soft
cotton cloth. The rest can be dried in the air.

The electrodes and caps should be stored in a dark and dry place. When assembling a product follow the research
scheme. In case of damage contact your supplier.
