The Epic II® Critical Care Bed is suited for use in the electromagnetic environment specified below. The
customer or the user of the Epic II® Critical Care Bed should assure that it is used in such an environment.

Portable and mobile RF communications
equipment should be used no closer to
any part of the Epic II® Critical Care Bed,
including cables, than the recommended
separation distance calculated from the
equation appropriate for the frequency of the
transmitter.

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 Epic II® Critical Care Bed is used
exceeds the applicable RF compliance level above, the Epic II® Critical Care Bed should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting
or relocating the Epic II® Critical Care Bed.
b
Over the frequency range 150 kHz to 80 MHz, field strengths are less than 3 V/m.
