Guidelines and manufacturer declaration – electromagnetic interference immunity
The KaWe MedCenter 5000 is designed to be used in the types of electromagnetic environments listed below.
The customer or user is responsible for ensuring that this device is used in such an environment.
Interference IEC 60601-
immunity test test level
Conducted HF-interference
according to 3 V rms
IEC 61000-4-6 150 kHz to 80 MHz
HF-interference 3 V/m
according to 80 MHz to 2.5 GHz
IEC 61000-4-3
Note 1: For 80 MHz and 800 MHz, the larger of the two values applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
a: Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur
radio, AM and FM radio broadcast and TV broadcast cannot be predicted with accuracy in theory. It is recommended that in order to assess
the electromagnetic environment caused by fixed HF transmitters, an electromagnetic site survey should be conducted. If the measured field
strength at the location at which the KaWe MedCenter 5000 is used exceeds the applicable compliance level stated above, the equipment
should be checked at each of its locations of use in order to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the KaWe MedCenter 5000.
b: For frequencies ranging from 150 kHz to 80 MHz, the field strength is less than 3 V/m.
Compliance Electromagnetic environment –
level guidelines
Portable and mobile HF communications equipment should
be used no closer to the KaWe MedCenter 5000 (including
its power cords) than the recommended separation distance.
The separation distance is calculated using various equations
depending on the transmission frequency.
3 V rms Recommended separation distance:
d = 1.2 √P
3 V/m d = 1.2 √P 80 MHz to 800 MHz
d = 2.3 √P 800 MHz to 2.5 GHz
"P" is the maximum output power rating of the transmitter in
watts (W) according to the transmitter manufacturer. "d" is the
recommended separation distance in meters (m).
Field strengths from fixed transmitters, as determined by
an electromagnetic survey of the site (a) are less than the
compliance level (b) in each frequency range.
Interference may occur in the vicinity of equipment marked
with the following symbol:
