Electromagnetic immunity
The EX3242-3D has been tested at the following compliance levels according to the testing requirements for
professional healthcare facility environments defined in IEC / EN60601-1-2.
Customers and users of the EX3242-3D must ensure that the EX3242-3D is used in the following environments:
Immunity test
healthcare facility
environments
Conducted distur- 3 Vrms
bances induced by 150 kHz - 80 MHz
RF fields
IEC / EN61000-4-6
6 Vrms
ISM bands between
150 kHz and 80 MHz
Radiated RF fields 3 V/m
IEC / EN61000-4-3 80 MHz - 2.7 GHz
Note 1 U is the a.c. mains voltage prior to application of the test level.
T
Note 2 At 80 MHz and 800 MHz, the higher frequency range applies.
Note 3 Guidelines regarding conducted disturbances induced by RF fields or radiated RF fields may not apply in all situa-
tions. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
Note 4 The ISM bands between 150 kHz and 80 MHz are 6.765 MHz to 6.795 MHz, 13.553 MHz to 13.567 MHz, 26.957
MHz to 27.283 MHz, and 40.66 MHz to 40.70 MHz.
a) Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile ra-
dios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To as-
sess 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 EX3242-3D is used exceeds the applicable RF compliance level
above, the EX3242-3D should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the EX3242-3D.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Guidance
Portable and mobile RF communications equip-
ment should be used no closer to any part of the
EX3242-3D, including cables, than the recom-
mended separation distance calculated from the
equation applicable to the frequency of the trans-
mitter.
Recommended separation distance
d = 1.2√P
d = 1.2√P, 80 MHz - 800 MHz
d = 2.3√P, 800 MHz - 2.7 GHz
Where "P" is the maximum output power rating of
the transmitter in watts (W) according to the trans-
mitter 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
