Electromagnetic compatibility
(EMC, IEC 60601-1-2:2014 4th Edition, Table 4)
Electromagnetic immunity
Thopaz + is intended for use in the electromagnetic environment specified below�
The customer or the user of Thopaz + should assure that Thopaz + is used in such
an environment�
Immunity
IEC 60601-1-2
Tests
test level
Conducted RF
3 Vrms
IEC 61000-4-6
150 kHz to
80 MHz
Radiated RF
3 V/m
IEC 61000-4-3
80 MHz 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�
NOTE 3 Proximity fields from RF wireless communications equipment were tested according
to Table 9 of IEC 60601-1-2:2014
Field strengths from fixed RF transmitters, such as base stations for radio (cellular / cordless)
a
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 Thopaz + are used exceeds the applicable RF compliance level
above, Thopaz + should be observed to verify normal operation� If abnormal operation is observed,
additional measures may be necessary, such as reorienting or relocating Thopaz + �
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m�
b
Compliance
Electromagnetic environment – guidance
level
Portable and mobile RF communications
equipment should be used no closer to any
part of Thopaz + , including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency
of the transmitter�
Recommended separation distance
3 Vrms
d = 1�2 √ P
d = 0�35 √ P
80 MHz to 800 MHz
d = 0�7 √ P
10 V/m
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 meters (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:
