Guidelines and manufacturer declaration - electromagnetic immunity
The MPR2 is intended for use in an electromagnetic environment as specified below. The customer or
user of the MPR2 should ensure that it is used in such an environment.

Portable and mobile RF communication
equipment should not be used closer to any
part of the device (including cabling and
sensors
) than the recommended safe
distance, which is calculated using the
relevant equation for the transmission
frequency.

P : transmitted power in W
The field strength of stationary radio
transmitters should be less than the
conformity level at all frequencies, as
demonstrated by an on-site
a
investigation.
b
Interference is possible in the area
surrounding devices carrying the following
symbol.
At 80 MHz and 800 MHz the higher frequency range applies.
These guidelines may not be applicable in all cases. The propagation of electromagnetic waves is
influenced by their absorption and reflection by buildings, objects and people.
a
The field strength of stationary emitters, such as mobile phone network base stations and mobile
agricultural broadcasting equipment, amateur radio stations, AM and FM radio and television
broadcasters cannot be accurately defined in advance. To determine the electromagnetic environment in
respect of any emitters, a study of the site should be consulted. If the measured field strength at the site
in which the MPR2 is used, exceeds the above conformity threshold, the MPR2 should be monitored, to
demonstrate that it is functionin
g correctly. If unusual characteristics are observed, additional measures
may be required, e.g. a changed alignment or another site of use of the MPR2.
b
The field strength should be less than 3 V/m in the frequency range 150 kHz to 80 MHz.
