Guidance and manufacturer’s declaration – electromagnetic immunity
The SIM™ system is intended for use in the electromagnetic environment specified below. The customer or the
user of the SIM™ system should assure that it is used in such an environment.

Electromagnetic environment - guidance
Portable and mobile RF communications equipment should
be used no closer to any part of the SIM™ system, 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 (m).
Field strengths from fixed RF transmitters, as determined by
an electromagnetic site survey

should be less than the
compliance level in each frequency range.
2
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.

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 SIM™ system is used exceeds the applicable RF
compliance level above, the SIM™ system should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orientating or relocating the SIM™ system devices.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
