Guidelines and manufacturer’s declaration – electromagnetic immunity
The blood pressure measuring device Mobil-O-Graph
®
is intended for use in the environment specified
below. The customer or user of the blood pressure measuring device Mobil-O-Graph
®
should ensure that it is
used in such an environment.

a
The field intensity of stationary transmitters, such as, for example, base stations of mobile telephones and
land mobile services, amateur radio stations, AM and FM radio and television transmitters, cannot,
theoretically, be accurately predetermined. In order to determine the electromagnetic environment as a
result of stationary transmitters, a study of the site’s electromagnetic phenomena should be considered. If
the measured field strength in the location in which the Mobil-O-Graph
®
is used exceeds the radio
compliance level specified above, the Mobil-O-Graph
®
should be monitored to verify normal function. If
abnormal performance characteristics are observed, additional measures may be necessary, such as, for
example, realigning or transposing the Mobil-O-Graph
®
.
b.
Within the frequency range of 150 kHz to 80 MHz, field intensity is less than 3 V/m
