Electromagnetic immunity
The EX2620-3D 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 EX2620-3D must ensure that the EX2620-3D is used in the following environments:
Immunity test
Test level for professional
healthcare facility
environments
Compliance level
Electromagnetic environment - Guidance
Portable and mobile RF
communications equipment
should be used no closer to
any part of the EX2620-3D,
including cables, than the
recommended separation
distance calculated from 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 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
a)
,
should be less than the compliance level in each
frequency range
b)
.
Interference may occur in the vicinity of equip-
ment marked with the following symbol.
Note 1
U
T
is the a.c. mains voltage prior to application of the test level.
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 EX2620-3D is used exceeds the applicable RF compliance level
above, the EX2620-3D should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the EX2620-3D.
b)
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
