Guidance and manufacturer´s declaration
Electromagnetic Immunity concerning Conducted RF and Radiated RF
The Medical Bed is intended for use in the electromagnetic environment specified below.
The customer or the user of the Medical Bed should ensure that it is used in such an environment.
Immunity Test IEC 60601
Test Level
Conducted RF 3 Vrms
IEC 61000-4-6 150kHz - 80 MHz
Radiated RF 3 V/m
IEC 61000-4-3 80 MHz - 2.5 GHz
d is the recommended separation distance in metres (m).
P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
a) Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey, a should be less than the compliance
level in each frequency range. b a Field strengths from fixed transmitters, such as base stations for radio, (cellular/cordless)
telephones, land mobile radios, amateur radio, AM and FM radio broadcast, and TV broadcast cannot be predicted theoretically
with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured field strength in the location in which the Medical Bed is used exceeds the applicable RF compliance
level above, the Medical Bed should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the Medical Bed.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
NOTE 1 Interference may occur in the vicinity of equipment marked with the following symbol:
NOTE 2 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 3 These guidelines may not apply in all situations.
Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
Compliance Electromagnetic, Environment
Level Guidance
3 V Portable and mobile RF communications equipment should be
used no closer to any part of the Medical Bed, including cables,
3 V/m
than the recommended separation distance calculated from the
equation applicable to the frequency of the transmitter.
Recommended separation distance
80 MHz to 800 MHz
800 MHz to 2.5 GHz
