INTRODUCTION
Precautions: Use of Medical Electrical System
Precautions for System installation
● All components of this medical electrical system may be installed within a limited patient environment (a radius of 1.5 m
around a patient) when all components are installed in accordance with the installation instructions using "Multi-tap with
Isolation Transformer", one of the system components.
● Prerequisite for installing other components (a PC, printer, video capture printer, video monitor, or other devices) which
do not comply with IEC60601-1 along with this system is that the electric power to the components is supplied from
"Multi-tap with Isolation Transformer". The electric power to these components supplied from an electric source other
than Multi-tap with Isolation Transformer (e.g., directly from wall outlets) may cause increased enclosure leakage current
or potential difference between protective grounds, resulting in the injury to the patient or operator. Please use the Multi-
tap with Isolation Transformer only for supplying the power to the components other than the system components.
● Any medical electrical equipment that is connected to this system to compose a medical system must comply with
IEC60601-1.
● Any non-medical electrical equipment that is connected to this system to compose a medical system must comply with
safety standards of IEC or ISO provisions applicable to such a non-medical electrical equipment.
● Do not use any additional multi-tap receptacle or extension power cable other than those specified to this system by
KOWA.
● Power supply to this system or "Multi-tap with Isolation Transformer" must be provided individually. (Do not route the
power supply through other multi-tap receptacle to the system or "Multi-tap with Isolation Transformer".)
● The power cable for an electrical device that compose a medical system must have durability that meets IEC60245/
IEC60227 or higher standards.
● Assure that the power supply is turned off when connecting an electrical device to the system.
● Do not turn on the power supply until all devices are completely connected.
● Do not place or install the devices and the system components on the unstable or inclined table.
Precautions for "Multi-tap with Isolation Transformer"
● Do not place "Multi-tap with Isolation Transformer" directly on the floor. Water droplets during room cleaning may enter
the multi-tap resulting in the component failure.
● The power supply cable to "Multi-tap with Isolation Transformer" must be connected to a power receptacle with a
protective ground terminal.
● When using "Multi-tap with Isolation Transformer" with a protective ground terminal, read the instruction for use attached
to the "Multi-tap" receptacle to familiarize yourself with the correct use before using it.
Daily Maintenance and Cleaning
1. System components
● Wipe the soiled outer surface with soft cloth from which water was firmly squeezed off. Do not wipe the exterior of
the system components with chemicals or solvents such as thinner and benzene. (Because LCD monitor screen
covers easily get scratched, lightly wipe with soft cloth such as gauze.)
● Refer to the instruction for use provided with each device for details of device maintenance and cleaning.
2. Power cables, connecting cables, and connectors
● Visually verify that all cables have no flaw or damage.
● Visually verify that earth leads of all components and protective ground terminals are securely connected.
● Disconnect the power cables from the power supply receptacles when you do not use the system for a long period of
time.
3. Others
● When you add a PC to the system for a filing purpose, captured images are stored in the hard disk drive of the PC.
Back up the data stored in the hard disk drive regularly since hard disk drives may have a mechanical or electrical
failure.
