Guidelines and manufacturer’s declaration – Electromagnetic immunity
The Suprasorb
®
CNP P3 therapy unit is intended for operation in an electromagnetic environment
as described below.
The customer or user of the Suprasorb
®
CNP P3 therapy unit must ensure that it is operated
insuch an environment.

Portable and mobile wireless devices should
not be kept closer to the Suprasorb

CNP P3
therapy units, including all cables, than the
recommended protective distance calculated
using the applicable equation for the transmission
frequency.
Recommended protective distance:
80MHz to 800MHz
800MHz to 2.5GHz
where P is the maximum nominal capacity of
the transmitter in watts (W) in accordance with
the transmitter manufacturer’s specifications
and d is the recommended protective distance
in metres (m). The field strength of stationary
transmitters should be less than the conformity
level at all frequencies according to anon-site
a
study.
b
Interference is possible in the vicinity of
devices bearing the following symbol.
NOTE 1: The higher frequency range applies at 80MHz and 800MHz.
NOTE 2: These guidelines may not be applicable in all cases. The transmission of electromagnetic parameters is influenced
bythe extent to which they are absorbed and reflected by buildings, objects and people.
a In theory, it is not possible to determine the field strength of stationary transmitters, such as base stations of radio phones
and land mobile radio services, CB radio stations, AM and FM radio and TV stations in advance with accuracy. A site study
of the prevalent electromagnetic phenomena should be taken into consideration for the determination of theelectromagnetic
environment with regard to stationary transmitters. If the field strength measured at the location at which the Suprasorb
®
CNP P3
therapy unit is used exceeds the above conformity levels, the device should be monitored to verify that it functions as intended.
If unusual performance characteristics are observed, additional measures such as amodified alignment or adifferent location
for the device may prove necessary.
b The field strength should be less than 3V/m over the frequency range from 150kHz to 80MHz.
