Guidelines and manufacturer declaration – Electromagnetic immunity
CardiAid is intended for operation in the electromagnetic environment specified below.
The customer or user of CardiAid should make sure that it is operated in such an environment.
Immunity tests
Conducted HF noise in
acc. with IEC 61000-4-6
Radiated HF noise in acc.
with IEC 61000-4-3
REMARK 1:
At 80 MHz and 800 MHz, the higher frequency range applies.
REMARK 2: These guidelines might not be applicable in all cases. The propagation of electromagnetic
parameters is influenced by the absorption and reflection of buildings, objects and human beings.
a. Field strengths of fixed transmitters, such as base stations for mobile/portable communication devices, cannot be
theoretically predicted with absolute certainty. In order to evaluate the electromagnetic environment based on fixed
HF transmitters, an electromagnetic investigation on-site should be considered. If the measured field strength should
exceed the HF compliance level specified above in the intended operating environment of the product, the product
should be monitored to verify that it functions normally. If abnormal function should be observed, additional measures
might be necessary, such as re-orienting or re-positioning the product.
b. Field strengths should lie under 3 V/m over the frequency range 150 kHz to 80 MHz.

12. Technical Information
Electromagnetic environment
Portable and mobile wireless devices should
not be used at distance from CardiAid
(including its power-line cables) smaller
than the recommended safety distance. This
is calculated according to the equation for
the relevant transmission frequency.
Recommended safety distance:
d = (1.17 m/V) * √ P
for 150 kHz - 80 MHz
d = (1.17 m/V) * √ P
for 80 MHz - 800 MHz
d = (2.33 m/V) * √ P
for 800 MHz – 2.5 GHz
P being the power rating of the
transmitter expressed in W according
to the specifications of the transmitter
manufacturer, and d the recommended
safety distance in m.
The field strength of stationary wireless
transmitters should be less than the
compliance level for all frequencies
according to an on-site investigation.
