Guidance and manufacturer's declaration – Electromagnetic immunity
Icare HOME is intended for use in the electromagnetic environment specified below.
The customer or the user of the Icare HOME should assure that it is used in such an environment.
Immunity test IEC 60601 Compliance level
Test level
Radiated RF 3 V/m 3 V/m
IEC 6100-4-3 80MHz to 2,5 GHz
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile
radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy.
To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured field strength in the location in which the Icare HOME is used exceeds the applicable RF
compliance level above, the Icare HOME should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the Icare HOME.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distances between portable and mobile RF communications equipment and
Icare HOME
Icare HOME is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the Icare HOME can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and Icare HOME as recommended below, according to the maximum output power of the
communications equipment.
Rated maximum output power Separation distance according to frequency of transmitter

d= 1,2 √P
0,01 0.12
0,1 0.38
1 1.2
10 3.8
100 12
For transmitters rated at a maximum output power not listed above, the recommended separation distance can be
estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power
rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.

Electromagnetic environment-Guidance
Portable and mobile RF communications
equipment should be used no closer to any part
of the Icare HOME, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency of
the transmitter.
Recommended separation distance
d = 1.2 √P
d = 1.2 √P 80 MHz to 800 MHz
d = 2.3 √P 800 MHz to 2 5 GHz
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey
should be less than the compliance level in each
frequency range.
Interference may occur in the vicinity of equipment
marked with the following symbol:
80 MHz to 800 MHz 800 MHz to 2,5 GHz
