Guidance and manufacturer's declaration - electromagnetic immunity
Pursuant to IEC 60601-1-2:2014 - Medical electrical equipment - Part 1-2: General requirements for
basic safety and essential performance - Collateral Standard: Electromagnetic disturbances
The equipment is intended for use in the electromagnetic environment specified below. The customer or the
user of the equipment should assure that it is used in such an environment.

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.
a
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 equipment is used exceeds the applicable RF compliance level
above, the equipment should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the
equipment.
b
Over the frequency range 150 kHz to 80 kHz, field strengths should be less than 3 V/m.

Portable and mobile RF communications
equipment should be used no closer to any
part of the equipment, including cables, than
the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.

according to the transmitter manufacturer
and d is the recommended separation dis-
tance in metres (m).
