Guidance and manufacturer's declaration – electromagnetic immunity.
The device is intended for use in the electromagnetic environment specified
below. The customer or the user of the device should assure that it is used
in such an environment.
IEC 60601 TEST LEVEL
3 V/m
80 MHz to 2.5 GHz
Electromagnetic environment - guidance
Portable and mobile RF communications equipment should be used no
closer to any part of the device, including cables, than the recommended
separation distance calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance:
d = 1.167 √P
d = 1.167 √P 80 MHz to 800MHz
d = 2.333 √P 800 MHz to 2.5 GHz
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 metres (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 equipment marked with the
following symbol:

±6 kV contact Floors should be wood, concrete or
ceramic tile. If floors are covered with
±8 kV air
synthetic material, the relative humidity
should be at least 30%.
3A/m Power frequency magnetic fields
should be at levels characteristic of a
typical location in a typical commercial
or hospital environment.
