4. Guidance and manufacturer’s declaration – electromagnetic immunity – for
equipment and systems that are not life-supporting
The device is intended for use in the electromagnetic environment speci ed below.
The user of the device should make sure that it is used in such an environment.

Portable and mobile RF communications equip-
ment 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
Where P is the nominal power of the transmitter in
watts [W] according to the information provided
by the manufacturer of the transmitter and d is the
recommended separation distance in meters [m].
The  eld strength of stationary transmitters at all
frequencies on site a should be, according to a
study, less than the conformity level b.
d = 1.2 P
80 MHz to < 800 MHz
d = 2.3 P
800 MHz to 2.5 GHz
Interference may occur in the vicinity of equipment
marked with the following symbol:
Note: These guidelines may not apply in all situations. The propagation of electromagnetic quantities is
a ected by absorptions and re ections of buildings, objects, and persons.
a Field strengths from  xed 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 of the stationary transmitters, a
site survey should be considered. If the measured  eld strength in the location at which the device is used
exceeds the above conformity levels, the device should be observed to verify normal operation. If unusual
performance characteristics are observed, additional measures may be necessary, such as a modi ed
orientation or a di erent location for the device.
b Over the frequency range 150 kHz to 80 MHz,  eld strengths should be less than 3 V/m.
