11.6 Separation distances for RF devices and Centurion
Recommended separation distances between portable and mobile RF communications equipment
and the Centurion 1500
+
.
The Centurion 1500
+
is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. AmeriWater or your Healthcare Provider will help prevent electromagnetic
interference by calculating and maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Centurion unit as recommended below, according to
the maximum output power of the communication equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation
distance
d
in meters (m) can be estimated using 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.
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.
