Precautions for Input Jack Use

NOTE

Do not perform EEG measurement without the Z, C3, C4, A1 and A2 electrodes.

Use of input jack Z

Connect the lead from the electrode (Z electrode) attached on the patient’s nasion to the input jack Z on the electrode

junction box. The purpose of this input jack is to eliminate AC interference positively.

NOTE

The input jack Z is also used for checking electrode impedance.

Use of input jacks C3 and C4

Connect the leads from the electrodes attached on the positions C3 and C4 to the input jacks C3 and C4 respectively.

NOTE

• The C3 and C4 electrodes are the system reference electrodes for EEG measurement.

• The input jacks C3 and C4 must be attached for EEG measurement even when the C3 and C4 are not

programmed in any montage.

Use of input jacks A1 and A2 (or FP1 and FP2), C3 and C4 during skin-electrode impedance check

When checking each electrode impedance, connect the leads from the electrode attached on the positions A1, A2, C3 and C4

to the input jacks A1, A2, C3 and C4 respectively.

NOTE

• The A1 and A2 (or FP1 and FP2) electrodes are the reference electrodes for skin-electrode impedance

check.

• The input jacks A1 and A2 (or FP1 and FP2) in addition to the Z, C3 and C4 must be attached for the

electrode impedance check.

Checking original electrode potentials for all active electrodes

Check the original electrode potential for all active electrodes by programming a montage with the system reference (Select

the 0 V button for reference electrode on the Montage dialog box). Refer to “Programming Patterns” in Section 4.

The digital EEG displays the EEG waveform in each channel by subtracting two electrode potentials selected to a montage.

The subtracted result will be incorrect, if the electrode attachment is not correct, the original electrode potential is flat or

unstable, or artifact is superimposed on the original electrode potential. Omit the measurement result if the displayed EEG

waveform is incorrect.

inside it could come out. If the solvent or toxic substance touches

your skin or gets into your eye or mouth, immediately wash it with a

lot of water and see a physician.

CAUTIONS

Liquid ingress

The system is not waterproof, so do not install the system where water

or liquid can get into or fall on the system. If liquid accidentally gets

into the system or the system accidentally drops into liquid,

disassemble the system, clean it with clean water and dry it

completely. After reassembling, verify that there is nothing wrong

with the patient safety checks and function/performance checks. If

there is something wrong with the system, contact your Nihon Kohden

representative to repair.

Environmental Safeguards

Depending on the local laws in your community, it may be illegal to

dispose of the lithium battery in the regular waste collection. Check

with your local officials for proper disposal procedures.

Disinfection and cleaning

To disinfect the outside surface of the system, wipe it with a non-

abrasive cloth moistened with any of the disinfectants listed below.

Do not use any other disinfectants or ultraviolet rays to disinfect the

system.

- Chlorohexidine gluconate solution: 0.5%

- Benzethonium chloride solution: 0.2%

Caution - continued

Transport

• Use the specified shipment container and packing material to

transport the system. If necessary, double pack the system. Also, put

the system into the shipment container after packing so that the buffer

material does not get into the inside of the system.

• When transporting a board or unit of the system, be sure to use a

conductive bag. Never use an aluminum bag when transporting a

board or unit which a lithium battery is mounted. Also, never use a

styrene foam or plastic bag which generates static electricity to wrap

the board or unit of the system.

Handling the system

• Because the outside surface of the system is made of resin, the

outside surface of the system is easily damaged. So when handling

the system, remove clutter from around the system and be careful to

not damage the system or get it dirty.

• Because most of the boards in the system are multilayer boards with

surface mounted electrical devices (SMD), when removing and

soldering the electrical devices, a special tool is required. To avoid

damaging other electrical components, do not remove and solder

SMD components yourself.

Measuring and Test Equipment

Maintain the accuracy of the measuring and test equipment by

checking and calibrating it according to the check and calibration

procedures.

Service Policy, Service Parts and Patient Safety Checks

Service Policy Our technical service policy for this instrument is to replace the faulty unit, board

or part or damaged mechanical part with a new one. Do not perform electrical

device or component level repair of the multilayer board or unit. We do not support

component level repair outside the factory for the following reasons:

• Most of the boards are multilayer boards with surface mounted electrical

devices, so the mounting density of the board is too high.

• A special tool or high degree of repair skill is required to repair the multilayer

boards with surface mounted electrical devices.

Disassemble the instrument or replace a board or unit in an environment where the

instrument is protected against static electricity.

As background knowledge for repair, pay special attention to the following:

• You can reduce the repair time by considering the problem before starting repair.

• You can clarify the source of most of the troubles using the information from the

troubleshooting tables. Refer to “Troubleshooting“ of this manual.
