Electromagnetic compatibility
Immunity test IEC 60601 test level Compliance level Electromagnetic environment – guidance
Portable and mobile RF communications
equipment should not be used 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.
Recommended separation distance
Conducted RF
IEC 61000-4-6 3 Vrms
150 KHz to 80 MHz
3 V rms
d = 1.2
d = 1.2 80 MHz to 800 MHz
d = 2.3 800 MHz to 2.5 GHz
Radiated RF
IEC 61000-4-3 3 V/m
80 MHz to 2.5 GHz
3 V/m
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).

.
Interference may occur in the vicinity of equipment
marked with the following symbol:
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 reflection from structures, objects, and
people.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile 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 MHz, field strengths should be less than 3 V/m.
