General Notice

1.) Designation of Peripheral Equipment Connectable to this Product. The peripheral which conforms
to EN60601-1-2 (IEC601-1-2), can be connected up to the LOGIQ™ 180 without compromising its
EMC performance. Failure to comply with the above instruction may result in poor EMC
performance of the product.
2.) Notice against User Modification: Do not modify this product. Unilateral user modification may
cause degradation in EMC performance. Modification of the product includes:
a.) Changes in cables (length, material, wiring etc.)
b.) Changes in system installation/layout
c.) Changes in system configuration/components
d.) Changes in means of fixing system/parts (cover open/close, cover screwing)
3.) Operate the system with all covers closed. If you open any cover for some reason, be sure to shut
it before starting/ resuming operation. Operating the system with any cover open may affect EMC
performance.

Countermeasures against EMC related Issues

Generally it is very difficult to handle with issues related to EMC. It is time consuming and expensive.
General counter measures for Electromagnetic interference with other equipment
1.) Electromagnetic interference may be reduced by positioning other equipment far away from the
system.
2.) Electromagnetic interference may be reduced by changing the relative location (installation angle)
of the system and other equipment.
3.) Electromagnetic interference may be reduced by changing wiring locations of power/signal cables
of other equipment.
4.) Electromagnetic influence may be reduced by altering the path of power supply for other equipment.

Notice on Service

Ensure all screws are tight after servicing. Loose screws may cause degradation in EMC performance.
Do not use the following devices near the LOGIQ™ 180 system. Devices which intrinsically
CAUTION
transmit radio waves such as cellular phone, radio transceiver, mobile radio transmitter radio-
controlled toy, etc. Use of these devices could cause the LOGIQ™ 180 system to perform
outside the published specifications. Keep power to these devices turned OFF when near the
system.
Medical staff in charge of the LOGIQ™ 180 system is required to instruct technicians, patients and other
people who may be around the system to fully comply with the above regulation
