Guidance and manufacture’s declaration – electromagnetic immunity
The DEVICE is intended for use in the electromagnetic environment specified below. The
customer or the user of DEVICE should assure that it is used in such an environment.
Immunity test IEC 60601 Compliance level Electromagnetic environment

Electrostatic ±6 kV contact ±6 kV contact Floors should be wood, concrete
discharge ±8 kV air ±8 kV air or ceramic tile. If floor are covered
(ESD) with synthetic material, the
IEC 61000-4-2 relative humidity should be at
least 30%.
Electrical fast ±2 kV for power ±2kV for power Mains power quality should be
transient/burst supply lines supply lines that of a typical commercial
IEC 61000-4-4 or hospital environment.
Surge ± 1 kV line(s) to ±1 kV differential Mains power quality should be
IEC 61000-4-5 line(s) mode that of a typical commercial
or hospital environment.
