Guidance and manufacturer's declaration – electromagnetic immunity
The device is intended for use in the electromagnetic environments listed below, and should
only be used in such environments:
Immunity test
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
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) F ield 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 pre-
dicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmit-
ters, an electromagnetic site survey should be considered. If the measured field strength in the location
in which the device is used exceeds the applicable RF compliance level above, the device should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the device.
b) O ver the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

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 = 1.2 √P
d = 1.2 √P 80 MHz to 800 MHz
d = 2.3 √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 deter-
mined 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
