Electromagnetic Compatibility
The performance of this device under electromagnetic environment complies with EN 60601-1-2: 2007.
Precautions for Safe Operation under Electromagnetic
Influence
If any sorts of electromagnetic wave, magnetic field, or static electricity exist around the device, noise
interference or malfunction of the device may occur. If any unintended malfunction or noise occurs
during monitoring, check the magnetic influence and take appropriate countermeasures.
The following are examples of the common cause and countermeasures.
WARNING Static Electricity
In a dry environment (room), static electricity is likely to occur. Take the following
countermeasures.
l Both operator and patient should remove any static electricity before entering the
room.
l Humidify the room.
WARNING Cellular Phone
l The radio wave may cause malfunction to the device.
l Cellular phones and radio sets should be turned off in the room (building) where
medical device is located.
Caution Lightning
A lightning nearby may induce excessive voltage to the equipment. If any danger is
suspected;
l Use the uninterruptible power supply system.
l Use the battery.
Caution High frequency noise interference from other device through the power outlet
l Check where the noise is originated and remove it using filtering device, etc.
l Stop using the device that is originating the noise.
l Use other power outlet.
