11.5 Guidance on electromagnetic immunity for non-life supporting
equipment
Guidance and manufacturer’s declaration – electromagnetic immunity
The Centurion 1500

is intended for use in the electromagnetic environment specified below. AmeriWater
or your Healthcare Provider 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 Centurion, including
cables, than the recommended
separation distance calculated from the
equation applicable to 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 strength from fixed RF transmitters,
as determined by an electromagnetic site
survey,
a
should be less than the
compliance lever 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 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 Centurion is used exceeds the applicable RF compliance level above, the Centurion should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the Centurion unit.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
