IEC 60601-1-2, Table 204
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.

Tests
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4
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 ab-
sorption and reflection from structures, objects and people.
a Field strengths from fixed RF 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 pre-
dicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmit-
ters, an electromagnetic site survey should be considered. If the measured field strength in the location in
which Thopaz is used exceeds the applicable RF compliance level above, Thopaz should be observed in
order to verify normal operation. If abnormal operation is observed, additional measures may be neces-
sary, such as reorienting or relocating Thopaz.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

environment – guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of Thopaz, including cables, than the
recommended separation distance calcu-
lated 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 rat-
ing of the transmitter in watts (W) accord-
ing 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.
