System Location
This wireless input unit measures very small electrical potential changes (5 to 200
µV). Ideally the instrument should be installed in a shielded room which provides
constant environmental conditions. Select the examination locations as follows and
also refer to “GENERAL HANDLING PRECAUTIONS”.
DANGER
• Never use the system in a flammable atmosphere (i.e. areas with
flammable anesthetics, concentrated oxygen, hyperbaric oxygen) or
in an environment in which an electrical arc could ignite an
explosion. Otherwise, the system will explode or catch fire.
• Never use the system in a high-pressure oxygen medical care tank.
Otherwise, the system will explode or catch fire.
WARNING
• Do not install the EEG System Program into a personal computer
which is not specified by Nihon Kohden and connect it to the system.
- If the personal computer does not satisfy the performance
specifications and safety standards which are required by Nihon
Kohden, the patient and operator may get electrical shock.
- Nihon Kohden does not warrant if hardware and/or software
becomes defective after installation.
• Only use the provided power cords. If another power cord is used, it
may cause electrical shock or other injury.
• For electrical safety, equipotential grounding is required. Consult a
qualified biomedical engineer.
• Connect only the specified instruments to the connectors or socket
marked with , by following the specified procedure. Otherwise,
electrical leakage current may harm the patient and operator.
Connecting to a Local Area Network
• When connecting the access point and electroencephalograph with a
local area network, connect the access point and
electroencephalograph so that the access point and
electroencephalograph are electrically separated from the local area
network according to the IEC 60601-1-1 “Medical electrical equipment
- Part 1-1: General requirements for safety - Collateral standard:
Safety requirements for medical electrical systems”. Failure to
follow this warning may cause electrical shock to the patient and
operator.
• Check that there is no damage on the surface of the network cable. If
it is damaged, it may cause electrical shock to the patient and
operator.
