Guidance and manufacturer’s declaration – electromagnetic immunity
Icare TA01i is intended for use in the electromagnetic environment specified below. The customer or the user of the Icare TA01i should assure
that it is used in such an environment.
Immunity test
IEC 60601 test level
Compliance level
Electromagnetic environment-Guidance
Portable and mobile RF communications equipment should be used
no closer to any part of the IcareTA01i, 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
where P is the maximum output power rating of the transmitter in
watts (W) according to the transmitter manufacturer and d is the
recommended separation distance in metres (m).
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:

NOT APPLICABLE
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 TA01i
is used exceeds the applicable RF compliance level above, the Icare TA01i 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 TA01i.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
Recommended separation distances between portable and mobile RF communications equipment and Icare TA01i
Icare TA01i is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the
IcareTA01i can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and Icare TA01i as recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (m) 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.
