5.3 Interference immunity
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.
Interference immunity
tests
IEC 60601-1-2 test
level

Floors should be made of wood or
concrete or finished with ceramic
tiling. If the floor is covered with
synthetic material, the relative
humidity should be at least 30%.
Electrical fast transient/
burst according to
IEC 61000-4-4
± 1kV for input and
output lines
± 2 kV for power supply
lines
± 1 kV for input and
output lines
± 2 kV for power supply

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
interruptions of the power supply, it is
recommended to have the UNIT
powered by an uninterruptible 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
commercial or hospital environment.
Note: U
T
is the AC supply voltage prior to application of the test level.
Portable and mobile radio equipment
must not be used within the
recommended working clearance
from the UNIT and its cables, which
is calculated based on the equation
suitable for the relevant transmission
frequency.
