Guidance and
manufacturer’s
declaration -
electromagnetic
immunity
The system is suitable for use in the specified electromagnetic
environment. The customer and/or the user of the system should
assure that it is used in an electromagnetic environment as described
below.

Mains power quality should be that of a
typical commercial and/or hospital
environment. If the user of the system
requires continued operation during
power mains interruptions, it is
recommended that the system be
powered from an uninterruptible power
supply or a battery.
Power frequency (50/
60 Hz) magnetic field
IEC 61000-4-8 3 3 A/m 3 A/m If display distortion or other abnormalities
occur, it may be necessary to position
the Anesthetic System further from
sources of power frequency magnetic
fields or to install magnetic shielding. The
power frequency magnetic field should
be immersed in the intended installation
location to assure that it is sufficiently
low.
Note: U
