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.

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

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.
