Guidance and manufacture’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.
Immunity test

IEC 61000-4-6
3 Vrms
150 kHz to 80 MHz 3
V RMS outside the
ISM band, 6 V RMS

80% AM at 1kHz
Not applicable
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.

d=2.3√p
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.
Field strengths from fixed RF
transmitters, as determined by
an electromagnetic site
survey, should be less than
the compliance level in each
frequency range.
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.
