The UNIT is intended for operation in the electromagnetic
environment specified below.
The customer or user of the UNIT should make sure that it
is used in such an environment.
3.3 Immunity to interference
Immunity interfer-
ence tests
IEC 60601-1-2 test
level
Conformance level Electromagnetic environment guidelines
Electrostatic dis-
charge (ESD) accord-
ing to IEC 61000-4-2
± 6kV contact discharge
± 8 kV air discharge
± 6kV contact discharge
± 8kV air discharge
Floors should be made of wood or concrete
or covered with ceramic tiling. If the floor
surface consists of synethetic material, the
relative humidity must be at least 30%.
Electrical fast tran-
sient/burst according
to IEC 61000-4-4
± 1kV for input and out-
put lines

The quality of the supply voltage should cor-
respond to the typical business or hospital
environment.
If the user of the UNIT requires it to con-
tinue functioning following interruptions of
the power supply, it is recommended to
have the UNIT powered by an uninterrupt-
ible power supply or a battery.
Magnetic field of

(50/60 Hz) according
to IEC 61000-4-8
3 A/m 3 A/m The power frequency magnetic fields
should correspond to the typical values
found in the relevant business and hospital
environment.
