Guidance and manufacturer’s declaration – electromagnetic immunity
(Table 204)
The SMP2 is intended for use in the electromagnetic environment specified below. The customer or the user of the SMP2 should assure that it is used in such an
environment.

Portable and mobile RF communications equipment
should be used no closer to any part of the
SMP2, including cables, than the recommended separation distance calculated from the
equation applicable to the frequency of the transmitter.
Recommended separation distance
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).
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:
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
Field 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 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 SMP2 is used exceeds the applicable RF compliance level above, the SMP2 should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the SMP2.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distances between
portable and mobile RF communications equipment and the SMP2
(Table 206)
The SMP2 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user
of the SMP2 can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the SMP2 as recommended below, according to the maximum output power of the
communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance
d
in metres (m) can be estimated
using the equation applicable to the frequency of the transmitter, where
P
is the maximum output power rating of the transmitter in watts
(W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for 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.
