Guidance and manufacturer's declaration - electromagnetic immunity
The equipment is intended for use in the electromagnetic environment specified below. The customer or the user of the
equipment should ensure that it is used in such an environment.
Immunity test IEC 60601 test level Compliance level Electromagnetic
environment - guidance
Portable and mobile HF
communications equipment
should be used no closer to
any part of the equipment,
including cables, than the
recommended separation
distance. The separation
distance is calculated from
various equations depending
on the frequency of the
portable and mobile HF
communications equipment:
Recommended separation

P is the maximum output
power rating of the
transmitter in watts (W)
according to the transmitter
manufacturer. d is the
recommended separation
distance in metres (m). Field
strengths from fixed
transmitters, as determined by
an electromagnetic site
surveya) should be less than
the compliance level in each
frequency rangeb).
