Guidance and manufacturer’s declaration — electromagnetic immunity
The bed is intended for use in the following electromagnetic environment. The customer or user of the bed must use it in
an environment specified here.
Immunity test
IEC 60601-1-2

RF Conductivity
IEC 61000-4-6
3 V
0.15 MHz to 80 MHz
6 V
ISM bandwidth between
0.15 MHz and 80 MHz
80% amplitude

3 V
0.15 MHz to 80 MHz
6 V

Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey, must be
less than the compliance level in each
frequency range.
Interference may occur in the vicinity
of equipment marked with the
following symbol:
Radioactive RF electro-

a. Field strengths from fixed transmitters, such as those of base stations for radio (cellular/cordless)
telephones, land mobile radios, amateur radios, AM and FM radio broadcasts, and TV broadcasts cannot
be predicted theoretically with accuracy. To determine the electromagnetic environment due to fixed RF
transmitters, an electromagnetic survey of the site should be considered. If the measured field strength in
the location in which bed is used exceeds the applicable RF compliance level above, bed should be
observed to verify whether or not it is operating appropriately. If an abnormal operation is seen, take
additional measures as needed, such as changing the location of use of the bed.
b. These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects, and people.
