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

NOTE 1: The higher frequency range applies at 80 MHz and 800 MHz.
NOTE 2: These guidelines may not be applicable in all cases. The transmission of electromagnetic parameters is influenced by
the 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 the
electromagnetic 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 a modified alignment
or a different location for the device may prove necessary.
b The field strength should be less than 3 V/m over the frequency range from 150 kHz to 80 MHz.

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
