Electromagnetic Interference Immunity
The care bed is intended for use in the electromagnetic environment specified
below. The customer or user of the care bed should ensure that it is used in such an
environment.

Portable and mobile radios,
including cables, should not be
used closer to the care bed than the
recommended working clearance
that is calculated by the equation for
the appropriate frequency.
Where P is the Power of the
transmitter in Watts (W) according
to specifications of the transmitter
manufacturer and D is the
recommended working clearance in
meters.
Field strengths from fixed
RF transmitters should, at all
frequencies, accordng to a site
survey, a-Note p.5 be lower than the
level of agreement be b- Note.p.5.
In the vincinity of equipment, bearing
the following symbol, interference .
Note 1: At 80 and 800 MHz, the higher frequency range must be taken.
Note 2: These guidelines may not apply in all situations. The propagation of
electromagnetic waves is affected by absorption and reflection from structures,
objects and persons.
a) Field strengths from fixed transmitters, such as base stations of mobile telephones
and land mobile radios, amateur radio, AM,FM radio and TV broadcast can not be
predicted with accuracy. To assess the electromagnetic environment due to fixed RF
transmitters, an electromagnetic site survey is recommended. If the field strength at
the location of the care bed exceeds the specified compliance level above
