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
Interference immu-
nity tests
IEC 60601-1-2 test level Compliance 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 finished with ceramic til-
ing. If floors are covered with syn-
thetic material, the relative humidity
should be at least 30%.
Electrical fast tran-
sient/burst
according to IEC
61000-4-4
± 1kV for input and output
lines
± 2kV for power cables
± 1kV for input and output
lines
± 2kV for power cables
The quality of the line power supply
should be that of a typical commercial
or hospital environment.
Surge voltages
according to IEC
61000-4-5
± 1kV differential mode
± 2kV common mode
± 1kV differential mode
± 2kV common mode
The quality of the line power supply
should be that of a typical commercial
or hospital environment.

The quality of the line power supply
should be that of a typical commercial
or hospital environment.
If the user of the UNIT requires it to
continue functioning following inter-
ruptions of the power supply, it is rec-
ommended to have the UNIT
powered by an uninterrupted power
supply or a battery.
Magnetic field of
power frequencies
(50/60 Hz)
according to IEC
61000-4-8
3 A/m 3 A/m Power frequency magnetic fields
should be at levels characteristic of a
typical location in a typical commer-
cial or hospital environment.
