The GoBed ® II MedSurg Bed, Model FL28C is suited for use in the electromagnetic environment specified below .
The customer or the user of the GoBed ® II MedSurg Bed, Model FL28C should assure that it is used in such an
environment .
Immunity Test IEC 60601 Test Level Compliance Level Electromagnetic Environment - Guidance

800 MHz to 2 .5 GHz
where P is the maximum output power rating
of the transmitter in watts (W) according to
the transmitter manufacturer and
d is the
recommended separation distance in meters
(m) .
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
a
should be less than the compliance level in
each frequency range .
b
Interference may occur in the vicinity of
equipment marked with the following symbol:
Note 1
At 80 MHz and 800 MHz, 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 GoBed
® II MedSurg Bed, Model FL28C is used
exceeds the applicable RF compliance level above, the GoBed ® II MedSurg Bed, Model FL28C should be observed
to verify normal operation . If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the GoBed
® II MedSurg Bed, Model FL28C .
b
Over the frequency range 150 kHz to 80 MHz, field strengths are less than 3 V/m .
