Guidelines and manufacturer's declaration - electromagnetic immunity
The Blood Pressure Device ri-medic model is intended for operation in the electromagnetic environment specified below.
The customer or the user of the Blood Pressure Device ri-medic should ensure that it is used in such an environment.

Note 1: At 80 MHz and 800 MHz, the higher value applies.
Note 2: These guidelines may not apply in all situations. The propagation of electromagnetic waves is influenced by reflection
and absorption by buildings, objects and people.
a
The field strength of stationary transmitters, such as base stations of wireless telephones and mobile field radio services,
amateur radio stations, AM and FM radio and television transmitters cannot be precisely determined theoretically in
advance. In order to determine the electromagnetic environment due to stationary HF transmitters, an investigation of the
location is advisable. If the field strength determined at the location of the Blood Pressure Device ri-medic exceeds the
compliance level indicated above, then the Blood Pressure Device ri-medic must be monitored with regard to its normal
operation at each place where it is used. If unusual performance characteristics are observed, additional measures such as
re-alignment of the Blood Pressure Device ri-medic or its removal to another place may be necessary.
b
In the frequency range of 150 kHz to 80 MHz, the field strength should be smaller than 3 V/m.

Electromagnetic environment - guidelines
Portable and mobile radio equipment should not be
used within a distance from the Blood Pressure Device
ri-medic, including cables, that is less than the
recommended safety distance as calculated by the
equation that is appropriate for the transmission
frequency.
Recommended safety distance:
d = 1.2√P
d = 1.2√P 80 MHz to 1000 MHz
d = 2.3√P 1400 MHz to 2.5 GHz
where P is the nominal power of the transmitter in
Watts (W) as specified by the manufacturer of the
transmitter, and d is the recommended safety distance
in meters (m).
The field strength of stationary radio transmitters
should be less than the compliance level b at all
frequencies as verified by an on-site test a
