Guidance and manufacturer's declaration – electromagnetic immunity
The bed is intended for use in the electromagnetic environment specified below. The customer or the
user of the bed should assure that it is used in such an environment.
IEC 60601 test
Immunity test

Conducted RF 3V rms
IEC 61000-4-6 150kHz to 80MHz
Radiated RF 3V/m
IEC 61000-4-3 80MHz to 2.5GHz
At 80MHz and 800MHz, the higher frequency range applies.
NOTE 1
These guidelines may not apply in all situations. Electromagnetic propagation is affected
NOTE 2
by absorption and reflection from structures, objects and people.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
a
telephones and 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 bed is used exceeds the applicable RF compliance level
above, the bed should be observed to verify normal operation. If abnormal performance is
observed additional measures may be necessary, such as reorienting or relocating the bed.
Over the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.
