Hill-Rom® P500 Therapy Surface User Manual (158251 REV 3)
Guidance and Manufacturer's Declaration - Electromagnetic Immunity
The P500 is intended for use in the electromagnetic environment specified below. The cus-
tomer or the user of the P500 should make sure it is used in such an environment.

Portable and mobile RF communications
equipment should be used no closer to any
part of the P500, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency
of the transmitter.
Recommended separation distance:
Where
P
is the maximum output power rating
of the transmitter in watts (W) according to
the transmitter manufacturer and
d
is the rec-
ommended separation in metres (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site sur-
vey
a
, should be less than the compliance level
in each frequency range

.
Interference may occur in the vicinity of
equipment marked with the following sym-
bol.
a. F
ield 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 P500 is used exceeds
the applicable RF compliance level above, the P500 should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such
as reorienting or relocating the P500.
b. Over the frequency range of 150 kHz to 80 MHz, field strength should be less than
3
V/m.
Note 1: At 80 MHZ and 800 MHz, the higher the 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.
