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
level
Conducted RF 3V rms
IEC 61000-4-6 150kHz to 80MHz
Radiated RF 3V/m
IEC 61000-4-3 80MHz to 2.5GHz
NOTE 1
At 80MHz and 800MHz, the higher frequency range 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
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.
b Over the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.
