13. Electromagnetic Compatibility
This device is a medical electrical instrument. The medical electrical instrument requires special care concerning electromagnetic compatibility
(EMC). This section describes its suitability in terms of electromagnetic compatibility of this instrument. When installing or using this instrument,
please read carefully and observe what is described here. (This instrument was tested on electromagnetic compatibility (EMC) based on
IEC60601-1-2: 2001.)
1. Carefully handle portable- or mobile-type radio frequency communication unit (RF communications equipment) since it may have an
adverse effect on this instrument resulting in malfunctioning.
2. Do not directly touch the pins of the connectors specified by the right figure. Also, take preventive measures before connecting cables
to these connectors.
Examples of preventive measures are as follows;
•
Pay attention to the humidity of the room (do not keep the humidity too low).
•
Place the instrument where conductive floor is used.
•
Wear non-polyester clothes.
•
Discharge your body by touching a large metal or the metal part of the instrument chassis.
•
Use a wrist strap against static electricity.
Also, provide guidance and training, in which warnings and precautions described above must be learned by all personnel who may use this
device.
The subjects shown below may be used when providing such guidance and training.
[About Static Electricity]
All materials hold positive (+) and negative (-) electrical charges. Normally, the number of positive (+) charges is equal to the
number of negative (-) charges. This is called “neutral” state.
However, when electrons are attracted by friction, contact or abruption, the material holds more negative charges or more positive
charges (this is called “electrically charged”).
The electricity which is generated here is called “static electricity”. Static electricity is generated anytime. However, electric charges
where humidity is high leak quickly as water which is a conductor is attached to the surface of the material and the electricity
passes through the water film.
By contraries, the material where humidity is low holds a few thousands of volts as it tends to remain electrically charged.
Static electricity which is built up is discharged through the earth via other conductors. This is called “electrostatic discharge”.
When an operator with static electricity touches electronic devices or parts, they discharge static electricity, which may cause
malfunction or damage.
Therefore, be very careful with electrostatic discharge when touching electronic devices or parts. Specific measures are as follows;
•
Pay attention to the humidity of the room (do not keep the humidity two low).
•
Place the instrument where conductive floor is used.
•
Wear non-polyester clothes.
•
Discharge your body by touching a large metal or the metal part of the instrument chassis.
•
Use a wrist strap against static electricity.
These are preventive measures to avoid discharging static electricity through electronic devices or parts.
3. Do not use other than recommended options or accessories, since they may affect this device or other devices resulting in their
malfunctioning.
4. This instrument is not designed such that it can be used adjacent to other instrument or placing one on top of another. Therefore, do not
apply such use. Nevertheless, if such use is inevitable, it is necessary to constantly monitor if the instrument is functioning normally
after such use has been adopted.
